Another important thing to remember is some drives like the LeCie drives
can be very touchy.  Do not use them to run programs or do much work is
the best way to prevent crashes so just use it for a back up drive.  And to
unmount the drive you might be safest shutting down the computer then
turning off the drive and rebooting your computer again instead of using
the normal unmount option.  I figured it out the hard way but your drive
may not give you the same problems I had.  And when I say I learned
the hard way I had to recover the drive which was more learning and
it does not always work recovering files.

You are correct in what you understood, that would be ideal - and I am sure 
would be valuable to many LiveCode users.  

However, I am desperate to know whether my idea will work or not, so, I can do 
some development & testing work using USBOverdrive, and then worry about how to 
package it all up neatly (and cross platform) later, if it does work.

You are welcome.  If the problem bugs you a lot maybe try
contacting the developer and explain it.  Possibly he will
fix it for you sometime or tell you a work around solution.

Thanks for the suggestion.

I downloaded this shareware, and it does the trick on Mac.  You can set it up 
so a joystick generates rawkey messages.  This won't be  a solution for 
delivering a final product, but at least I will be able to do some development 
work.

The only fly in the ointment is that even when disabled, USBOverdrive blocks 
scrolling on my Magic Mouse.  It is bad enough that I travel England stroking 
other people's mice and shouting "D,Oh!" but now I do it on my own mouse.

Re: data from USB joystick

[-=>JB<=-]

Exactly and that is why I did not mention it in my first response
because it sounded to me like he wanted to write code that is
going to allow his program to communicate with a USD device
and not depend on anything but his program.

Which brings us back to my answer that I was writing a stack
that uses the serial port commands.  I can send it to anyone
who wants it and it will open the port and allow you to send
text but after a certain amount of text is sent nothing else will
be sent which makes me think Rev is using a memory buffer
that fills up and unless you can empty this buffer you will not
be able to send more text.

I found to communicate with a USD device on a mac with Rev
which is now Livecode you need to open the serial port and
then you need a driver to communicate with the USB device.
Someone gave me a driver that might work but I never finished
the stack for a couple of reasons.  One of the reasons was the
problem of the buffer overflow or what ever is causing things
to stop.  At the time Mark Schonewille was thinking the file
might need to be sent as a binary so I coded it to be sent as
a binary and the problem was exactly the same.  It might be
possible to use the ADT commands to control the buffer if
you are using a modem but even if you can I am not sure
if they would work on everything.

So it sounds if he wants to do it he will need to rely on some
external programs like you mentioned but if anyone knows
the answer or wants the serial port stack I have created to
test please let me know.

so that it's immediately available as soon as the game is launched.
◊  The mouse settings allow you to speed up your daily tasks by assigning 
useful actions to all the extra buttons and wheels in your USB mouse. You'll 
typically want to assign a control-click to the right button for easy 
contextual menu acces, and enable document scrolling if your mouse has a 
scrolling wheel.
◊  The Control Panel includes an active help feature that explains each command 
and option as you move the cursor around.

Re: data from USB joystick

[stephen barncard]

So that simple $20 USB joystick that Richmond mentioned is not the exact
solution that the original poster wanted?
That USB Service plus is great for labs but did you see the prices of that
stuff? And it probably has to be shipped from Germany.

Re: data from USB joystick

[-=>JB<=-]

If I understood him correctly he wants to plug any standard USD game
device into his computer and control it with LiveCode.  For him to use
the USB Service Plus gadget he might get it to work but then anyone
using the game he develops would need to buy the gadget which is
not going to happen so that idea does not seem suitable.

I had mentioned I was working on a serial communications stack that
was going to allow you to also control X10 and similar home control
devices accessing a X10 USB or similar device with Livecode.  This
appears to be feasible by opening the port with livecode and then
using the right driver to access the USB device.

The problem I had was after opening the serial port I was able to
send a certain amount of text and then rev would not send anymore
which makes me think they are using a memory buffer in their code
that fills up.  So if that is what is happening even if you are able to
control the USB device it will stop after the buffer is full which means
you will need to close the port and open it again which empties the
buffer allowing you to send the same amount of text again.  That is
going to cause problems if you need to close the port and open it
again during game play.

I think the above is missing the point; presumably David has a USB 
joystick and a USB port
on his target computer; so no need to do "the down-and-dirty" with the 
soldering iron.


What he needs to do is ascertain is, for example, whether the USB 
joystick sends Unicode chars when
it is moved, rather like the chars for right-arrow and left-arrow on a 
keyboard, and whether
they are interpreted by the computer as mouseDown and mouseStillDown 
signals.


I have a Belkin Nostromo (silly gaming pad) which I use for 
RunRev/LiveCode programming:
now it comes with a set-up control panel where one can set all the keys, 
wheels and twiddly things
on it to do what one wants - having set up one's preferences 
RunRev/LiveCode can pick up

whatever I do on the Nostromo without any trouble at all.

However, I suspect that David is trying to be somewhat cleverer than me, 
insofar as he wants
to 'skip' the requirement of an intermediate, platform specific, set-up 
panel / driver-thingy.


My own inclinations would be to run round the corner and buy a crappy 
USB joystick and plug the
thing in, and then set up some silly little stack that will pick up the 
signals from the USB stick


[ they cannot be that other-worldly ]

and see whether they can be interpreted as KeyDown, rawKeyDown type 
signals . . .

Thanks Sarah,

I wrote a wee stack to look at keystrokes (not as nice as yours), but it seems 
that HID compliant devices work in a much more complex way than simply 
generating characters.  Except of course the keyboard/mouse family, which do 
nothing but generate characters.  I even bought a repro-retro amiga joystick in 
the hope that it worked the old fashioned way, but it doesn't.  I really want 
the mechanical element of pushing and pulling to be present, otherwise I would 
use a mouse or a keyboard.   

There are utilities out there which enable HID devices to be configured to 
generate keystrokes, so they can be used by folks with a disability to use 
whatever software they need to use, rather than the intended games.  However, 
that would mean running a third party utility then running my stack.  Not a 
nice option.

There are some assistive devices that seem to generate keystrokes, but they are 
shockingly expensive. Makes you realise there is a real disability tax when it 
comes to using computers. I also had expected a few Revvers to have written 
standalone games that use joysticks, but maybe that domain is restricted to the 
die-hard X-planers and shoot em ups.

Does the joystick produce keyDown/Up or rawKeyDown/Up messages? If so,
you could map out the numbers that each motion triggers and have your
app react accordingly.
There is a utility on my web site that detects keystrokes and displays
the various codes for them.

Thanks Craig, 

Fischertechnik® brings back memories of painfully standing barefoot  on bits my 
brother left lying around on the floor.  

However what I want is the other way round.  I have joysticks, and just want to 
be able to access the HID pages receiving their data. I know they are 
recognised by the OSs, and know that the data is captured if it is not directed 
somewhere specific.  I just don't understand where, or what means might be used 
to read it.  My guess it is pretty low level stuff, but who knows?  Maybe 
someone has already done something like this in Rev.

Accessing data from HID compliant USB device

[David Glasgow]

Hello folks,

This one has been churning around in my head for ages, and I finally bought a 
couple of joysticks to experiment with.  

I want to build a standalone that responds to joystick input.  Nothing 
requiring huge amounts of data or processing, just detection of joystick 
position -> onscreen response scaling or moving an image. 

I can understand the basic principles of HID, but can't get to grips with where 
the data goes in either Mac or Windows, and what would be involved in capturing 
it in Rev.  I have found some developer articles which address this, but they 
relate to other languages (VB & RB, I think).

Any advice would be most welcome.

Thanks

Awesome!! Thanks so much. Should provide an excellent stepping off point

more interesting popped up :-)


That often happens. There's too much interesting software to write! :)

Happy to help.

My introduction to the programming community was through a BBS run by my 
local Mac user group.  I posted my first question there about 
manipulating certain Mac resources, and one of the members patiently 
explained how it worked and what I needed to do to get my job done -- 
just two hours later.


That was a magic moment for me, one repeated often enough that I began 
to understand the true value of the programming community: no one has to 
solve every problem by themselves so long as they have a modem. :)


At that time I'd worked in three different industries, but from that 
moment on the programming community distinguished itself for me by being 
comprised of people who give uncommonly high value to sharing knowledge 
freely. I've just been paying it forward ever since.


Challenges like this USB thang are good examples of this dynamic at 
work:  about half a dozen people contributed to that handler, and now we 
all have something that will save us time as we move on to the next one.

Absolutely.  This has been a group effort, with valuable input from Ken 
Ray, Phil Davis, Peter Alcibiades, Matthias Rebbe, and others, so the 
least I can do is share the fruit of our collective labor.


Below is a handler that handles Mac and Win, with a placeholder for 
Linux but I don't need that yet so I'll write it in a few weeks when I 
get to it.


It examines the currently-mounted volumes and returns a list of those 
volumes which are removable, using AppleScript for the Mac side and data 
from the Win registry for Windows.


Each line of the return value has three items separated by tabs:

- Drive label/letter (I use this to display in a list)
- available space (useful for my installer)
- mount point or drive letter (needed for writing to the drive)

I have four different removable drives I've been testing with (card 
reader, U3, plain USB flash drive, and camera), and the AppleScript 
method that was suggested here was the only one which easily recognized 
my card reader along with all the other more "normal" drives; relying on 
info from system_profiler alone did not provide the mount point, needed 
to write files to the drive.


Note that U3 drives show up as two volumes, one writable and one not. 
The non-writable volume of a U3 drive has zero available space, and 
that's used to exclude them from the list without having to slow things 
down by attempting writes to each disk to test that (though also do that 
on the selected volume later on in a different handler just to make sure 
before proceeding with the install).


This is a bit sloppy in some parts since it's a small part of a larger

job done well enough for now (you may need to clean up email-imposed 
line wraps):

Re: Finding USB volumes on Win

[Matthias Rebbe]

Richard,

you could query all mounted devices from the shell

get shell("reg query  HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices")

This return all mounted devices. You then just have to look for the specific 
one.
Not that what you expected, but maybe it helps.

Re: Finding USB volumes on Win

[Richard Gaskin]

Another snag:

The key I need is named "\DosDevices\G:", at this path:

HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

So it would seem that if I escape the backslashes in the key name I'd be 
good:


 get 
queryRegistry("HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\\\DosDevices\\F:")


But no go.

I've tried many different combinations of escapes, and no escapes at 
all, and no matter what I try the result says, "bad key" and the data 
returned is empty.


Any clues?

Thank you, Richard, but I've been getting the volume IDs from the 
registry.  The challenge I have this morning is to find which volumes 
are removable.


Since I last wrote I discovered that the info at 
HKEY\Local_Machine\System\MountedDevices\ seems to have what I need.

Richard,

This has been working for me:

 put line i of the volumes into x
 put getvolumesn(X) into z
end repeat

function GetVolumeSN pDiskLetter
  local volumeSerialNumber
  -- Supports both "C", "C:" and "C:\" styles
  put char 1 of pDiskLetter & ":" into pDisk
  set the hideConsoleWindows to true
  put shell("dir " & pDisk) into tDirData
  get matchText(tDirData,"Volume Serial Number is

  if it is true then
return volumeSerialNumber
  else

This is good to know.  I have an old Sega Activator I've been trying to
figure out how to get going under OS X.

http://www.youtube.com/watch?v=ql-UZv3AS-E

It has Sega's proprietary gamepad connector, but there was an old gamepad
adapter box that allowed connection of gamepads to Mac systems.  Sadly this
used an ADB connection, so between 2 port adapters and Mac OS 7 software,
I'm not sure if this FrankenController is worth trying to resurrect, but it
was a cool device, especially when used as a trigger for music.

When I was over in England I had a sudden urge to 'steal' (admittedly
from myself) the keyboard from my G3 iMac as it is so compact. So,
thought I had better leave a keyboard behind in case I forget to take
this one back.

So:

bought a very, very cheap no-name USB keyboard ('for Windows NT, XP,
and Vista') for £10 (about as cheap as you can go in England). Of course
it wouldn't work with Mac OS X 10.3.9 . . .

So:

http://www.macupdate.com/info.php/id/8955   (USB monitor)

and everything magically sprang to life. . .

Presumably, if the OS recognises the device itself (rather than just some
dedicated program) things should be OK with Rev ??

Re: USB dance-pad with Rev?

[Phil Davis]

Yes, what Björnke (and Dave C) said is true - in USB termonology the 
device interaction requirements are defined by the class it belongs to.


   * Mass Storage class = flash drives etc. Rev lists them in "the volumes"

   * Communications class = Björnke's "serial over USB" - controller
 boards, modems etc that have a command set of their own. These
 usually have drivers that Rev lists in "the driverNames" although
 they don't always get listed. (I have a 'deviceNames()' function
 somewhere (thanks to Dar Scott and Ken Ray) that returns a more
 complete list - I'll see if I can dig it out and post it.) These
 require that you open driver / read from driver / write to driver
 / close driver. I learned a lot from Sarah Reichelt about working
 with this device type. Here is a description of her work with one
 such device:
   http://www.pdslabs.net/usb/rev-usb1.pdf

   * HID class = keyboards, mice etc.

There are about a dozen USB device classes in all, but the ones listed 
above are the ones most relevant to the current discussion.

Someone poke Phil Davis, he's the king of Rev and USB and done some very
interesting work.

Some makers do produce SDKs for use with the device, though a lot of them
are for C++ developers. If it does have such an SDK, it may be possible to
write a Revolution external.

Sorry Richmond but it should not matter about user definable keys or  
not, as the device driver should be monitoring that and then sending  
the appropriate message to the receiving applications..


In theory you can get an external to listen to the messages sent by  
the system, but as demonstrated in my recent external there are issues  
(on the Mac anyways) with the compiled application engine and  
listening for (some?) external events..

I don't think that's right. Each USB device identifies what "class" of device

Human Interface Device which covers keyboards, mice, etc. If the device is of that class, 
then you should be able to get key messages. But there are other classes (Audio, 
Communications, Vendor Specific, etc.) where key messages probably aren't sent.

Yes, you are right; I'm sorry, I was thinking only of the class of USB

Mice,

http://catalog.belkin.com/IWCatProductPage.process?Product_Id=390404 )
requires settings to be set outwith the target program before it can 
interact with that program.


I had to set up a settings file called "Revolution" using the Nostromo 
Preference Pane (Mac OS X) so that

when I pressed button 06 it would paste from the clipboard.

If you are 'just' developing your stack for your own use then you should 
have no problems, but, in the
case of authoring for other end users who may have USB devices with 
user-editable settings you will

be up a gum tree.

Apart from my 'blah' above; the thing to know is whether your target USB 
device has USER-EDITABLE settings.

I don't think that's right. Each USB device identifies what "class" of device 
it is, and the host device (computer) loads the appropriate driver. One such 
class is Human Interface Device which covers keyboards, mice, etc. If the 
device is of that class, then you should be able to get key messages. But there 
are other classes (Audio, Communications, Vendor Specific, etc.) where key 
messages probably aren't sent.

Richmond,
I agree, but how can we pass messages from system to RunRev ?

I have used a Belkin Nostromo Gamepad n52 for about 3 years as a

All USB devices will send some sort of keyDown signals and/or pointer

USB dance-pad with Rev?

[Nicolas Cueto]

I'd like to connect a USB dance-pad to my PC and then make a stack
that does game-type stuff with the signals sent in by the dance-pad.
But I don't know if Rev can read in signals other than from the mouse
or keyboard.

Anyone know if and how this can be done... or perhaps have even
actually done it?

Thanks.

You're welcome!

Here is an improved version of the original handler. It adds a "Device:" 
label to the device name and replaces the single "Volumes:" label before 
ALL volume descriptions with a "Volume:" label before EACH volume 
description (should make it easier to break out descriptions of each 
partition on a USB drive).


function macUsbDrives

   put shell("system_profiler -detailLevel full SPUSBDataType") into tData

   -- convert data to one line per USB device
   replace (colon & cr & cr) with numToChar(245) in tData -- device name
   replace (cr & cr) with numtoChar(250) in tData
   replace cr with tab in tData
   replace numtoChar(245) with (colon & tab) in tData
   replace numtoChar(250) with cr in tData

   -- remove records for all but USB drives (English data only)
   filter tData with "*Detachable Drive: Yes*"

   -- remove space-padding from items in each line
   set the itemDel to tab
   repeat for each line tLine in tData
  put empty into tNewLine
  repeat for each item tItem in tLine
 put word 1 to -1 of tItem & tab after tNewLine
  end repeat

  -- insert a device tag at beginning of device description
  delete last char of item 1 of tNewLine -- trailing colon
  put "Device: " before item 1 of tNewLine

  -- remove single 'volumes:' tag at beginning of all volume 
descriptions

  replace "Volumes:" & tab with empty in tNewLine

  -- insert a "volume: " tag at the start of each volume description
  replace (colon & tab) with cr in tNewLine -- break after each 
volume name

  repeat with x = 1 to (the number of lines in tNewLine - 1)
 put "Volume: " before last item of line x of tNewLine
  end repeat
  replace cr with tab in tNewLine

  -- append finished line to rest of data
  put cr into last char of tNewLine
  put tNewLine after tNewData

Hi Richard,

I believe this does include the volume names as they appear in the 
Finder. Look for the "Volumes:" tag in each output line.

Very helpful Phil, and I appreciate your posting it, but unfortunately 
the issue I found with using system_profiler is that it doesn't report 
the volume name as it appears to the user on the desktop.


I had hoped there would be some reasonably simple way to get a list of 
mounted volumes that looks something like this:


  

...where  is the name as it appears in the Finder, 
 is either "/" or "Volumes/", and  is 
either ATA, SCSI, CD/DVD, USB, etc.


With what I've learned in this thread it seems I may be able to use 
output from system_profiler checked against output from AppleScript 
calls to obtain such a list.


For the future, I see that Jeanne DeVoto had submitted an RQCC request 
for "the detailed volumes" which could do what I need if implemented 
as described there:

<http://quality.runrev.com/qacenter/show_bug.cgi?id=101>

In the meantime, it looks like I have some parsing to do and some 
homework to figure out the details of getting this info for Win Vista, 
Win 7, and Linux.  I'll post the result here once I get it working.

Here is an simplified 'system_profiler' output approach. It returns one 
tab-delimited line of info per detachable USB storage device, with all 
the data items known to system_profiler for each device. NOTE: It 
expects system_profiler output to be in English.



function macUsbDrives
   -- get USB device info from system profiler
   put shell("system_profiler -detailLevel full SPUSBDataType") into tData

   -- convert data to one line per USB device
   replace (colon & cr & cr) with numToChar(245) in tData -- device name
   replace (cr & cr) with numtoChar(250) in tData
   replace cr with tab in tData
   replace numtoChar(245) with (colon & tab) in tData
   replace numtoChar(250) with cr in tData

   -- remove records for all but USB drives (English data only)
   filter tData with "*Detachable Drive: Yes*"

   -- remove space-padding from items in each line
   set the itemDel to tab

If so, you could iterate through the listed volumes using a couple of
applescripts to determine whether the drive was local (false if it's a
network drive) ejectable (false if it's internal) and then if you 
get two
false results you can attempt to open a file on the volume. If that

you an error then the drive is write protected. If it passes all 
tests then

you're left (presumably) with an external USB or Firewire drive.


The "passes all tests" list can also includes mounted .dmg files.

True - but only if it's modifiable (if not, trying to open a file for
writing will give you a "can't open file" error in the result). One other
test you can throw in is to get the format of the disk. DMGs appear to
always return 'Mac OS Extended format' while USB sticks *may* be in another
format (mine all appear to be MS-DOS (FAT32), which returns 'unkown format'
from applescript).

The "passes all tests" list can also includes mounted .dmg files.

Thanks for posting this - very helpful.

The relevant applescript snippets are...

tell application "System Events" to get the local volume of disk
[volumepath]

tell application "System Events" to get the ejectable of disk [volumepath]

Would that do it?


Works a treat!  And simpler than parsing the XML data from system_profiler.

Thanks!

Re: Finding the name of a USB volume

[Peter Brigham MD]

FWIW, I was unable to find a way of getting the name of the currently- 
connected USB printer without asking the user when it is first  
encountered and storing the associated printername (as listed in the  
printer dialog under printers with available drivers). With printers  
there seems to be no way of fetching the user-chosen name of the  
device from any shell call for USB info, at least as far as I have  
been able to discover. But I am hardly knowledgeable about shell  
calls

To help make this simple for the user I'd like to present a list of

Phil Davis was kind enough to share some pointers in his libUsbDrive  
library (see <http://pdslabs.net/usb/index.html>), which has me  
exploring the use of shell calls on OS X to system_profiler, e.g.:


  get shell("system_profiler -xml SPUSBDataType")

While the info returned there contains a lot of very useful stuff,  
the one thing I'm not able to find is the name of the volume as it  
appears to the user on the desktop.


Well, sometimes, that is.

It seems that if I've named the drive in the Finder, the Volumes  
section of the data returned from that shell call is filled in, and  
includes the apparent name of the volume.


But drives which haven't been given a name on a Mac system appear on  
the desktop as "Untitled", and although the data from the  
system_profiler shows it as a removable drive there is no Volumes  
section included and hence no way to know the name of the drive as  
it appears to the user.


When there is is a Volumes section the _name key there shows the  
name as it appears in the Finder, but drives that have not  
explicitly been given a name appear as "Untitled" or "Untitled 1",  
etc., in the Finder and the corresponding _name key from  
system_profiler is something different (for example my card reader  
device has a _name value of "Generic USB2.0 card " in  
system_profiler, but on the desktop it appears as "Untitled 1").


Do any of you know a way I can use shell or AppleScript to obtain  
the apparent name of a removable drive when system_profiler fails to  
return it?


Extra bonus points:  what shell calls would I use to get this info  
on Linux?  I think I have the Windows side of things down, but I'll  
need to work out the Linux side soon.

Finding the name of a USB volume

[Richard Gaskin]

I'm making a custom installer in which I want to provide the option of a

Way cool!  Thanks for posting that.  Somehow I'd missed it, but after 
your post I dug up RR's press release:

<http://www.runrev.com/company/press-release-archive/service-usb-plus/>

This caught my eye there:

   SERVICE USB plus is a proven, robust control technology in
   professional implementations for industry, tradeshows and
   entertainment. With this release, it can be used, for example,
   to drive special effects such as flashes or fog machines at
   concerts and tradeshows, directly from within Runtime
   Revolution applications.

Hmmm...I can envision all sorts of things I'd like to do for my next Rev 
seminar presentation.  With Rev and Service USB I can now replace Steve 
Jobs' entire support staff with some really cool robots to drive lights, 
projection, lasers, and a fog machine  :)


Okay, there are a million more useful things that can be done with it, 
but I can dream can't I?


Don Rossi, is this not the thing you need to take CyberRave into the 
21st century?

Re: Addressing Hardware - particularly usb port

[Phil Davis]

P.S. - Here's how I send a command to the device after the 
"myDeviceNames" function tells me which devices are available:


global gCurrentDevice

on mouseUp
  -- locate the device driver
  put myDeviceNames() into tDevice
  filter tDevice with "usbmodem*"
  if tDevice = empty then
 answer "Can't find device."
 exit to top
  end if
 
  if the number of lines in tDevice > 1 then

 answer "Multiple device drivers!" & cr & tDevice
 exit to top
  end if
 
  put (item 3 of tDevice) into gCurrentDevice

  open driver gCurrentDevice for update
  put the result into fld "result"
  write tMyCommand & cr to driver gCurrentDevice -- be sure the CR is 
there!

  put the result into fld "result"
end mouseUp

Re: Addressing Hardware - particularly usb port

[Phil Davis]

Hi Peter,

What platform are you running?

Also, is your meter is a USB Communications Class device? In other 
words, does it have a defined command set (like a modem)? If so, you'll 
need a driver of some sort; or as others have said, the simplest 
approach would probably be to use a USB-to-Serial converter between the 
computer and the device.


Here's an article that might help some. It is based on info from Sarah 
Reichelt, who uses USB+Rev all the time:

of, do it in C or forget it?

Re: Addressing Hardware - particularly usb port

[camm29]

Yes it can, but you must have a Virtual port that appears to be a serial comm 
port.

Rev will only send/receive Commands/Data  via serial RS232 , the only problem 
then is the USB meter data requirements.

Addressing Hardware - particularly usb port

[Peter Alcibiades]

Is it possible in Rev to address a usb device directly?  I've no experience 
of this sort of thing, but have a USB meter which I need to talk to.  

If not, does anyone know if its possible from the shell?  Or is this a case 
of, do it in C or forget it?

Re: USB barcode scanner?

[Peter Alcibiades]

They are LED or Laser.  The difference is range and fragility.  The LED ones
have to be used much closer up to the code, like 6 inches, but they are very
robust.  The Laser ones can be used quite a distance away, but don't drop
them.  I prefer LED.  They will get dropped.

As others say, the 'wedge' ones act like a keyboard, and need no drivers. 
But, and it may not matter in your application, bear in mind that they send
the characters they read followed by either return or enter but not both. 
This has a couple of consequences.  If you allow keyboard entry of codes as
well, obviously you have to handle both enter and return.  Also I had some
timing problems.  I made caps D send mouseup to a Discount button. The user
wanted for the cashier to be able to either do discounts by just using the
reader, or alternatively, just using the mouse. Problem was that it sent
mouseup to the Discount button and then sometimes but not always then sent
return when the user was expected to first enter the amount of the
discount I fixed this by the brute force method of sending to an
invisible dummy button, waiting a fraction of a second, and then sending
mouseup on, so absorbing the enter. 

Sarah's little stack was very useful in decoding what exactly the reader was
sending.  If you want to handle some keypresses, this means that you know
exactly what is being sent and so you can harmonize the keyboard and the
reader.  

kbarcode, if you can run Linux apps, is a great free package for generating
bar codes and printing bar code labels.  Bear in mind that if you generate
labels in a word processor, like for a cash register laminated sheet, and
there are quite a few free bar code fonts out there that can be used for
this, you have to use start/stop characters, and these differ from Windows
to Linux, and I assume the Mac will be different as well.  Its * for Linux,
and if I recall correctly its ! in Windows. You can find yourself staring at
the thing in frustration wondering why the shop label codes work perfectly,
but the ones you have just made up do not.  This is probably why.

I found the really hard issue to be not so much this stuff, as the tradeoffs
you end up considering between convenience and security.  Very hard to
strike the balance.  You have to spend some time thinking like a thief and
craftily installing logs, and whatever you do you'll miss something.

Hi Tim:

I haven't used it extensively but I have an IntelliScanner Mini from here:
http://www.intelliscanner.com/

The biggest selling point for me on this unit is the size -- it could
literally fit on a keyring.  It works in 2 modes: batch, where you scan
codes unplugged and it stores codes in onboard memory; and tethered, where
scans are immediately sent to the front most application (or one of the
applications that ships with the unit).

It's been a while since I last used it, but I just installed the latest
dashboard software on OSX 10.4.11, and ran it with Revolution 3.  Scans are
immediately transferred to an open field, along with a return character.

FWIW.

As the others have said, any scanner that operates in keyboard wedge
mode will be fine. A lot of them come with cables sold separately, so
don't forget to specify that you want USB. I recommend a scanner with
multiple scan lines - it easier to use as the barcode doesn't have to
be positioned so exactly.

I have used scanners made by Unitech and by Datalogic, both with Macs
& Revolution applications.

Cheers,
Sarah

I wrote a stack some years ago that worked with a barcode reader, which 
I had never seen and did not have access to. I just used normal 
keydown/keyup and "on returnkey" handlers, and it all worked fine. There 
was no difference between keyboard entry and barcode entry. So what you 
say works. I warned the client they'd have to test, and it never failed 
in any way.


 I think Jacque was on the Evangelists list, or was it Mac Marines? It 
was a while ago. Over 20 years of mail-lists. The mind boggles.


It was the Evangelists list, but I only read it, I never posted. And 
yes, I can't believe where the time goes.

What Stephen said. One other thing to know is that the barcode  
scanners can have their behavior modified by scanning barcodes in the  
booklet that comes with them. For example, you can have the scanner  
send a return after it's finished reading the barcode. That can be  
handy for your input routine, so it knows when the scanner has  
finished sending.


There is no difference at all between a user typing on a keyboard, and  
the scanner sending its keystrokes, so if you have an application  
where a user is supposed to type into one field, and a scanner grabs a  
barcode without showing the text captured, your user could trigger the  
scanner while typing into the visible field, and they will see the  
barcode numbers typed in for them. That may not matter, but it could  
influence your design, you would want to make sure not to set up  
situations where the user can easily be confused.


Another setting for the scanner is the baud rate (they're really  
serial, with USB converters). Set that to as high as you can, and even  
then the apparent typing speed is not very fast.

Re: USB barcode scanner?

[Stephen Barncard]

Timothy ,
Most of the bar code devices operate like a keyboard input device out 
of the box as a straight barcode scanner (i.e. outputs a translation 
of the barcode in text), others have features like storage where the 
scanner does not have to be tethered to the computer, can dump later, 
Wifi, etc.


Most of them won't mention the Mac, even though everybody's 
conforming to standards. So don't let the PC part deter you, unless 
you need software to do more than recognize IPC symbols. It appears 
your scripts will do the rest.


 It's interesting in the peripherals world, when often many USB and 
Firewire devices built to standards, are sold with no reference to 
Macintosh at all in the ads and packaging, even though they work 
perfectly (and often install without drivers) and are a significant 
part of their sales are to mac customers. This is especially true of 
hard drives and network routers. Incredibly ignorant of the marketers 
if you ask me, and a wasted opportunity.


I used to be an annoying Mac Evangelist (remember those?) when we 
felt we had to fight every fight against the PC 'hegemony', or we'd 
be stuck with the alternative in the future. Today, Apple's strong, 
hip, visionary, and makes solid products these days that sell 
themselves, so I don't have to do that anymore.


 I think Jacque was on the Evangelists list, or was it Mac Marines? 
It was a while ago. Over 20 years of mail-lists. The mind boggles.




Hello!

Can anybody recommend a usb barcode scanner that I can get to work 
with rev?  I using rev 2.81 and a Mac.  I've got my POS app working 
nicely now and it's time for the next step...adding a scanner.


Thanks!
