Re: $%@$% ROM image files!!!
You might want to try the latest POSE because it's supposed to let you transfer the ROM over USB. The instructions say to copy the USBPort.dll to the POSE install directory. There will be an option enabled after you do this to transfer over USB. Although the option was there, it didn't work for me. I have a different device (older) than yours, however. It worked fine for me with m500 that I am developing for at the moment. There is a section in palm emulator user guide called: Transferring a ROM image over a USB Connection that should tell you what to do. I am not sure about how it works with other devices as I have a serial cable for my own palm IIIxe, and hence havn't tried to download over USB for that. - Veronica -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Re: Palm OS 3.5 :SelectDay() -different events on normal rom and debug roms
And the reason they do that is because on a real device there may not have been enough memory to save the bits behind the modal form. And in that case the OS will use frmUpdate to tell the form behind the modal form to redraw itself. A form is buggy if it does not properly respond to frmUpdateEvent -- so the debug ROMs help you find that bug in your form. Refer to the Palm OS SDK for details on frmUpdateEvent. Jayanarayanan M N [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I have a form with to select a date. In the normal form, selecting date does not generate a frmUpdateEvent(and application works fine). In a debug rom- Palm OS 3.5-en-colordbg.rom- selection generates and frmUpdateEvent. Is this correct behavior? Am I making some trivial mistakes? Palm OS Bible by Lonnon R Forster. Page 169.

http://www.escribe.com/computing/pcpqa/m71474.html
That looks like it.
SrmReceive() doesn't return until at least 8 bytes are in the
buffer
in OS 5. The app I'm working on needs to respond to single byte
polls and the same exact code worked fine in the preOS 5 world,
so
I'm thinking that there must be a bug in their stuff.
as you identified, this is most likely a problem with implementation
(either be it hardware limitation or software). its not that common
people use the serial manage and send a single byte over it *g* or,
begad.. it could be a bug in your code :)
have you tried isolating the code slightly?
Yes. See below.
error = SerReceiveCheck(m_serRefNum, serNumBytes);
if(serNumBytes = 1)
{
char serNumBytesChar1 = serNumBytes + 0x30;
FrmCustomAlert(DebugAlert, serNumBytesChar1, NULL, NULL);
}
This Alert message will ALWAYS display 8 in OS 5. OS 4 displays 1.
see if SrmReceive is actually thread blocking - that is, doing
nothing
until 8 bytes of data is actually put into the buffer. are you sure
that no errors are occuring with those calls?
Yes, I check for errors on SrmReceiveCheck() and SrmReceive(). I
don't call SrmRecieve() if SrmReceiveCheck() returned an error.
looking over the code, i see some potential issues.
1. serNumBytes -- set to zero by SrmRecieveCheck
- should you reall go in and try to receive bytes if this value
is zero? your if (!error) should probably include a check that
there are bytes to recieve. i dont know what calling SrmReceive
with 0 bytes actually does - could do some funky stuff.
you might want to also set it manually to zero before that call
to be on the save side, your optimizer might be doing some funky
register tweaking which is known to make fun bugs at times as
well
I have turned all optimizations on the compiler off. I will try only
calling SrmRecieve() if SrmReceiveCheck() returns a non-zero value,
but that still doesn't explain why SrmReceiveCheck() will only return
when I have 8 bytes in the buffer.
2. SrmReceive call, are you sure you want to pass -1 as the timeout?
-1 means wait forever. maybe serNumBytes is being set to 8
magically
and, SrmReceive sits and waits forever for these 8 bytes? try
setting it to 10 or so (100ms) - at least, give it enough time
to
get X bytes.
I've tried -1, 0, 1, 2, 3, 4, 5, 6, 7, and 8 as the timeout values.
SrmReceiveCheck() will always wait until I have at least 8 bytes in
the buffer.
while this wont be part of your problem, it is a little nitpick :)
char serNumBytesChar = serNumBytes + 0x30; // convert to ASCII
FrmCustomAlert(DebugAlert, serNumBytesChar, NULL, NULL);
isn't the best way to do this :) your passing the address of a char
variable onto your CustomAlert - but, you cannot guarentee that the
byte directly following is actually a \0 character.
You are correct, you are nitpicking. This is just debug code. The
end user doen't care how many bytes are in the buffer. It's a quick
and dirty way to convert a single digit to ASCII without allocating
more memory. The alert does display some garbage after the text, but
I know what I'm looking for. For all other Custom Alerts I do
allocate more memory.
since it also works on OS4, it could potentially spell out a bug
with PACE - but, lets not count your chickens before they hatch.
it could just be programmer error *g*
Dude, I have worked for a week on this crap. I have sat down with
multiple engineers that have worked on the Palm OS and embedded
software before. We have spend well over $500 worth of time into
this problem and no one can explain what is going wrong. My company
is willing to fork over the $500. I appreciate your attempt at
helping. I'll let you know what the experts say.

are you saying it thread blocks, or, doesn't return a value until there

serNumBytes = 512;
// Grab bytes from the UART buffer
serNumBytes = SrmReceive(m_serRefNum, m_serUARTBuffer, serNumBytes, -1,

}
that will tell you if it is actually waiting for 8 bytes to come in

its old code :) but, technically should work the same way. since
you are only looking for one byte, you can have a pretty low

On Mon, 10 Mar 2003 07:36:15, ritmanik writes: SrmReceiveCheck() does not return until at least 8 bytes are in the buffer. This isn't an accurate or a complete statement of the problem. Sending only one character at a time from an external terminal to the m550 serial port seems to work just fine. So SrmReceiveCheck() *will* return after only 1 byte is in the buffer, but after a slight delay (a few milliseconds it seems). It may be that the OMAP chip itself takes some time to shift incoming serial port data down its built-in 8-byte FIFO.

floats in syslib shared library under prc-tools 2.2?
I'm trying to build a simple Hello Lib example syslib library using prc-tools 2.2.
Other than the open, close, sleep, and wake functions, the only function in the
library looks like this:
void HelloLibSquare( UInt16 refnum, float in, float* out ) {
*out = in * in;
return;
}
When I build this library, the build-prc step gives me a warning:
global data ignored. I used m68k-palmos-objdump --section-headers to view the
hellolib file and it shows nonzero-sized .data and .bss segments. Curiously, if I
comment out the first line of the body of HelloLibSquare, the warning goes away and
the .data and .bss segment sizes are zero. The same is true if I make my arguments
ints instead of floats.
I'm using the GaussLib example from prc-tools-samples as the basis for this, and that
example builds and runs fine. Any idea why I can't use float (or double--that bombs,
too) for my arguments?
thanks -
Dave

Masking images on 0S 3.5
Hi Everyone, I think this was covered previously, but I've searched the archive and can't find any topics on it anymore. I'm writing a game that uses an offscreen window to blit images to the main window using a Mask image to maintain the background image of the main window. I'm using winMask followed by winOverlay to accomplish this. Everything works perfectly on OS4.0 and OS5, but on OS3.5, I get strange results. The images appear skewed (slanted) when they're drawn to the main window. Here are the steps I am using: 1) copy background image from offscreen to main window using winPaint 2) copy Mask image (black pixel = keep) from offscreen using winMask. 3) copy bitmap image from offscreen to main using winOverlay. Once again, this method works perfectly on OS4.0 and OS5. I only get strange results on OS3.5 so I suspect there is a bug in the OS relating to wincopyRectangle and transparency issues. Any help would be greatly appreciated! Thanks! __ Do you Yahoo!? Yahoo!

Re: Palm OS Developer Membership Upgrade
I wrote in a previous post: I have found the same problem on an application that I am working on. It works fine on pre-OS5s but fails on the Tungsten. I have talk to Palm directly and indirectly and have not received any helpful information. My application is a real time app and must be able to process serial information as it enters the serial port. However I have found that serial input port is buffer incoming bytes of data over a very short time period (3-4 milliseconds). This short time period is an eternity for my application, which results in the application failing to deliver the desired results. I do not have the option of trying my application on a Sony NX series because my application uses an adapter utilizing the Palm universal connector. I hope that Palm is listening to this! Since that post i have been in touch with an engineer from Palm Source. The following message was sent to that engineer: I checked the code and looks like FCR7:2 is set 00 (to generate an interrupt every 8 bytes) and SCR7 = 0 and TLR7:4 = . Unfortunately we cannot do anything about this because it is a already shipping product. I am not sure if the future products will keep it like this or change it to 1 byte buffering. The fowwing message was his response: Unfortunately this is below the OS level and cannot be controlled by tweaking the OS. Changes have to made to underlying layer below OS, i am not sure if they can just fix it easily. Will let you know when i find more information on this. The real problem here is that the OMAP processors serial UART3 is not sending incoming bytes directly to the SrmReceive FIFO buffer when it is determined that that incoming byte is legitimate. SrmReceiveCheck check for the number of bytes in the SrmReceive FIFO Buffer. I hope this may help someone and that the next release of the OS fixes the problem for us developing real time serial applications. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

are you getting the same results on PalmSim as well?
No, the code works fine on the OS 5 Simulator. SrmReceiveCheck()
works as expected.
Another interesting thing I found is that the Simulator also supports
the old serial manager, but the Tungsten T does not.
If the code is changed to the following:
// Find out if we have bytes in the queue
serNumBytes = 0;
error = SrmReceiveCheck(m_serRefNum, serNumBytes);
if (!error)
{
char serNumBytesChar = serNumBytes + 0x30; // convert to ASCII
FrmCustomAlert(DebugAlert, serNumBytesChar, NULL,
NULL); ..
A zero is displayed in the Custom Alert. Therefore, if there
aren't
bytes in the queue, SrmReceiveCheck() will return immediately in
OS 5
as expected. But if there are bytes in the queue, SrmReceiveCheck
()
will wait until there are at least 8 before returning, which
isn't
good for my app, becuase it's too late to respond to the poll.
so, best solution is to avoid SrmReceiveCheck() :) seems that is
coded to thread block/return nothing until 8 bytes are in the
buffer.
That's what I'll have to do I guess.
i found some old code that would grab one byte at a time from
the
serial port, but, it made calls specific to XXXReceiveWait and
XXXReceive.
We haven't tried this method, but I'll try it out. Thanks for
your help!
its old code :) but, technically should work the same way. since
you are only looking for one byte, you can have a pretty low
timeout value without slowing things down too much :)
i had to dig deep in my archives for that code.. its a bit dusty.
Thanks again!

Re: Re: floats in syslib shared library under prc-tools 2.2?
I gave that a try but it didn't work. The linker complained about not being able to
resolve the reference to the function from the jump table. I tried static on both
the declaration and definition, and then on each separately, with the same result each
time.
I went back to the original GaussLib example (which I was able to build successfully)
and added the following three lines of code to the GaussLibCreate function:
float a,b;
a=2.0;
b=3.0*a;
This was enough to generate the global data ignored message from build-prc. If I
comment out the third line, the message goes away. Why would this line cause global
data to be created? Arg. Is it a compiler or linker switch set wrong?

Serial comm delays in OS 5 (m550) (was: Re: Palm OS Developer Membership Upgrade)
See message #85960. I'm not sure if this is releated, but I am not able to process any events during my serial communication since I need to respond to the byte l within 2-3ms of receiving it. Processing system events causes me to miss the poll. Maybe try keeping the serial routine in a loop that prevents system events from beeing processed and see if you get the same result. Also, I am using asyncronous (RS485) communication. Possibly the RTS/CTS signal in syncronous comm causes the UART to interrupt immediately. Since I am not using these signals, no interrupt is created. I'm not sure which you are using or if this could be an issue. Check some of the other threads (#85437 for example) on this issue and you should be able to see what you're doing differently than I am. --- In [EMAIL PROTECTED], Ron Nicholson [EMAIL PROTECTED] wrote: On Mon, 10 Mar 2003 07:36:15, ritmanik writes: SrmReceiveCheck() does not return until at least 8 bytes are in the buffer. This isn't an accurate or a complete statement of the problem. Sending only one character at a time from an external terminal to the m550 serial port seems to work just fine. So SrmReceiveCheck() *will* return after only 1 byte is in the buffer, but after a slight delay (a few milliseconds it seems). It may be that the OMAP chip itself takes some time to shift incoming serial port data down its built-in 8-byte FIFO.

Conduits on Linux
I'm finally at the point where I'm ready to start working on a conduit for my app. However, it looks like both the Bible and the O'Reilly books (at least the First editions that I have) only talk about conduits on Windows, and I'm on a Linux system. Before I start tearing into the gpilot source, can somebody point me to a good place to learn about conduits on Linux? Thanks /dwight -- Dwight N.

Re: UIColorSetTableEntry problem
There is still something that is not very clear. Yes, I want to use gray colors in versions between 3.0 and 3.5, yes I can legaly set 2- bit depth, yes I set fore and back colors with WinSetColors, yes I write directly to screen memory to do some of the operations, BUT : when I use WinSetColor and change the fore and back colors the controls I draw after that are using new colors - that's ok. The problem is that when you move the scrollbar for example it messes up. In OS 3,5 you can see in the OS code that they use UIColorSetTableEntry, every time a scroll bar is being drawn, to set its colors. If you use UIColorSetTableEntry to change the proper UI colors the scroll doesn't mess up. So in OS 3,5 draw routine uses UI color list to draw the scroll bar. The question is : what is scroll draw func using in OS prior to 3,5 (and bigger than 3,0). --- In [EMAIL PROTECTED], Aaron Ardiri [EMAIL PROTECTED] wrote: We said the same thing. :-) The OS 3.0 does not support grayscale -- no built in API support. 3.0 supports grayscale screen at the Win API level, but not for user interface UI objects or drawing.

How can I trap HotSync Signal?
Someone said using hotsync signal on OS5.(sysNotifyEventDequeuedEvent)
And then how can I use hotsync signal on OS4?
I read about SysTrap...
So I tested my sample program using i705,but it doesn't work.
What's wrong in my program?
Is it right hotsync using IRQ1 line?
ex)
static Err MyFunc()
{
EvtEnqueKey('a',0,0);
return 0;
}
Err TestFunc()
{
void *Func;
Func = SysGetTrapAddress(sysTrapHwrIRQ1Handler); // Is it right using
hotsync?
if(Func)
{
SysSetTrapAddress(sysTrapHwrIRQ1Handler,MyFunc);
}
..
}

Stopping a Sound Stream using Sound Streaming API (PalmOS 5)
Hi all I have an application which passes the mp3 data file to a mp3 library which in turn decodes the mp3 data and uses the streaming API of Sound Manager to play it simultaneausly. This mp3 library is a native code library and the mp3 application is a 68K application. I am working on Palm OS 5. The problem which I am facing is - I have a stop button in the application which when pressed should stop the playing of sound.Basically when the stop button is pressed, I am calling an API of mp3 library which stops the playing of sound through SndStreamStop().But once the mp3 song starts playing, the stop button doesn't respond.On pressing it doesn't gets pressed. It seems in my application the event of stop button being pressed is not even received by the application. Looks like the application doesn't accept any other event while the song is being played. Please advise on how I can solve this problem. Thanks in advance __ Do you Yahoo!? Yahoo!

Re: UIColorSetTableEntry problem
I'm having trouble communicating, because it seems everyone focused on the absolute technical accuracy of my original response. I was trying only to give a contextually accurate response for your specific question. Both Ben Combee and I answered your original question. You can't do it on OS 3.0 through OS 3.3 because the OS is hard coded to use black and white. The APIs for controlling the UI object colors are only available on OS 3.5 and higher. (Hopefully this time my answer is both contextually correct and 100% technically accurate ;-). Ok, I can already see a way that my answer is not technically accurate. Sure you can do it on OS 3.0 through OS 3.3 -- for example, you could create your own code to replace the OS code for the UI objects. The point is, there is no built in way to do what you want on OS 3.0 through OS 3.3. If you feel it's important to do on those OS versions, then you need to do it yourself from scratch (or find someone else's code that has already done it all from scratch -- I don't know of anyone who has done so, and it seems like quite a bit of work for very little benefit, so personally I would never bother, even if a paying customer thought it was extremely important ;-). g3BEPA [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] There is still something that is not very clear.

Re: $%@$% ROM image files!!!
From: Calamity Jane [EMAIL PROTECTED] Can someone explain to me why these files are such a closely guraded secret? They're the operating system of the device. You get a license when you buy a PalmOS device in the same way as Windows is often bundled with a PC, or MacOS with an Apple. Try downloading a free copy of Windows or MacOS and the PalmOS insistence that you buy the ROM image comes into focus.
