Re: Float and 64-bit alignment and endianness in ARM
At 12:55 AM 2/17/2004, you wrote: At the dev con, I was reminded that in ARM code, not only had 2-byte integers be aligned on 16-bit boundaries, but 4-byte integers also had to be aligned on 32-bit boundaries. What about 8-byte integers? On 64-bit boundaries? Does this apply to floating point data as well, eg. 4-byte floats on 32-bit boundaries and 8-byte doubles on 64-bit boundaries? The ARM4T architecture only requires 4-byte alignment. On some ARM cores with FP support, double math is faster with quantities aligned on an 8-byte boundary, but there shouldn't be any access issues. Lastly, does ARM little endianness affect floats and doubles or are these endianness-independent formats? Yes, these format are endian-reversed from 68K. (BTW, it was good to meet you last week!

On my box, I also have a Windows 98SE running inside of win4lin. When I compile in native Linux it is 19 seconds. Using win98se in win4lin it is 5 minutes. Hardly any activity noticable during the compile.. the hard disk blinks maybe once every 5 seconds. It's just painfully slow. I think it may have something to do with console programming in win32.

Re: TimGetSeconds and TimGetTicks
Michael Jones wrote: I need to do a timer in my program with precision greater than seconds. I am aware of TimGetTicks, but was unsure how predictable this is. The way the API reads makes me think that SysTicksPerSecond can return different results at different times - which, over the period of time that is being tracked, might fluctuate and distort the results if my end calculation depends on consistently timed SysTicks being produced. Consider the following pseudo-code: startTime = SysGetTicks(); ...then once timer is over doing the following: endTime = SysGetTicks(); elapsedTime = endTime - startTime; numSeconds = elapsedTime / SysTicksPerSecond runRemainder = (elapsedTime % SysTicksPerSecond) * 100 Is this reliable? Anyone have something they have used? Thanks! Mike Yes, this is what we are doing too and it's reliable as long as the device stays awake. The result given by SysTicksPerSecond() will be constant on any given platform. It may vary between platforms, but that's actually the whole point. Some platforms count milliseconds, others count centiseconds, and the Mac simulator counts Mac OS ticks == 1/60 s. Note the that SysTicksPerSecond() is an OS function while sysTicksPerSecond is a compile-time macro. Also, it seems to me that the emulator counts _emulated_ ticks, not wallclock time ticks, so if you break into the debugger the tick counter will simply freeze. Don't know if this is true when device debugging though. IIRC, I also got very similar results running benchmarks on a real M505 and on an emulated M505. --Martin -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Re: Pressing the SELECT button on T|T resets Palm
I have an application and it has an About screen. On the About screen is one button, OK. If the T|T SELECT button is pressed briefly, the Palm resets. Make sure you don't have a graphical button on the modal form. This does cause a TT to reset when Select is pressed, but if you handle the keyDownEvent for the Select button in your event handler you can prevent it (in the handler you can queue a ctlSelectEvent for the OK button). I think only the TT has this problem; it works OK on T3s and other devices AFAIK.

Standard Palm OS databases do not have fields. Instead, think of the database as an array of binary objects, where each binary object it just a memory handle pointing to a chunk of data. The interpretation of the chunk is up to the program; the OS doesn't do any interpretation for you. There actually are a couple of fields in the chunk header -- a unique ID for the record and a few bits to set a category, but other than that, it's just data. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
RE: Database creation
Hi, First of all palm database is not exactly a database. Writing to palm database is like writing a structure to a file using fwrite() function in c. Going by this logic, U will be having a structure for which u will create a instance and fill the data members. Using DmNewRecord() u will get a memory handle to the new record. U will lock the memory handle and using Dmwrite() u will assign the instance of structure to the memory handle and unlock the memory handle. After that u will use DmReleaseRecord() to release the record u have newly created. Hope this helps...

I seem to recall an old console project which gained a considerable speedup by simply making it window-based. I fear that the win32 console stuff is performance crippled in some way. One thing which can slow down Cygwin enormously on Windows is active virus scanners (the on-line variety, which monitors file opens/close/access). This is a real problem when there is a lot of subshell activation (configure, libtool and friends). Running configure in prc-tools with virus scan active took forever for me. When disabling it it ran like a charm. It is at least one order of magnitude difference in elasped time. Of course, cince Cygwin emulates the POSIX calls it will always be slower than Linux on the same hardware. Just my 5 cents ...

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/
Crash sublaunching Digitizer on T3
Greetings,
I have a function that sublaunches the Digitizer app for calibration using
this code:
{
LocalID digiLID = 0;
UInt32 result = 0;
Err err = 0;
Boolean hascursor = true;
// is the cursor blinking?
hascursor = InsPtEnabled();
// locate digitizer app
digiLID = DmFindDatabase( 0, Digitizer );
if (digiLID)
{
if (hascursor)
InsPtEnable(false); // hide cursor
// launch the digitizer applet
err = SysAppLaunch(0, digiLID, 0, sysAppLaunchCmdNormalLaunch, NULL,
result);
if (hascursor)
InsPtEnable(true); // show cursor if it was there before
}
}
This has been working successfully on all PalmOS3 and higher devices,
including various OS5.x devices, but causes a crash on the Tungsten T3 both
on the real device (which I don't have) and on the T3 Simulator. When I run
it on the sim, the calibration completes okay, but then I see this error
message on return to my calling app:
I:\Morpheus\arm\Core\Emul68K\SrcSlowEmu\Run68K.c, Line:3109, Odd aligned

Re: One day in problem (2 Month With CW)
I have a problem,
Your basic problem is a lack of C skill. Programming
Palm OS, in many ways, requires skills that left
common use fifteen years ago (it's certainly been
that long since I was paid to write C code on any
other platform). It's worth finding a good book
on C programming and reading the section on strings
carefully.
Or, perhaps better, walk away from C and use one
of the higher level languages such as AppForge,
NSBasic or Java. There are also tools targetted
at specific types of applications.
The detail that has led me to this conclusion are:
typedef struct PacienteStruc
{
Char *Nombre ;
A Char * is not a string in the same sense as
VB or Java Strings. A Char * is a pointer to a
the start of a string in the same way that an int *
is a pointer to an integer.
The structure you've defined has no space in it to
store strings. If each member was defined as
Char Nombre[NOMBRESIZE];, for instance, then it
_would_ have space to store a string.
newRecord.Nombre = Bill;
This sets your pointer to a constant stored in the
application. This doesn't copy anything anywhere
and definitely won't store that name in the database
record. You need to read about StrNCopy, StrNCat,
StrLen and the like.

Resize an offscreen window
Is there any way to resize an offscreen window. I am creating the offscreen window to draw formatted text using: WinCreateOffscreenWindow (width, height, screenFormat, err); And scrolling using WinCopyRectangle. The scrolling needs to be fast, so I need to draw the entire page up front. Because of the formatting, it is not possible to know what size screen I will need, until it renders it. When the formatted text exceeds the originally allocated window size, I would like to grow the window until I run out of heap space. Is there any way to do that and preserve the window contents? This will become much more of an issue when I convert the code to use double density when available.

Re: One day in problem (2 Month With CW)
I am not sure why you are getting a null handle for DmNewRecord, but you
have some C issues. You are saving a structure of pointers to the db which
may or may not be valid when you open the database record the next time. If
you change your structure to use char arrays, you can write it directly to
the db in one call using DmWrite. Otherwise you will have to use some
string packing mechanism - there are plenty of examples of that around.
Make sure your OpenDatabase function returns a valid DmOpenRef handle.

MemPtrNew / MemPtrFree
Hello,
Since I'm a Palm OS newbie, I need some help. I'm debugging an applicaiton
using the Emulator and found out that the application sometimes gets memory
leaks error.
Ben Combee also suggested that I should use MemPtrNew to decrease my stack
size in my previous thread.
So, I've decided I should take a serious look at using MemPtrNew and
MemPtrFree to make the application more efficient.
However, I don't know how to use them.
This is the existing code in my Pilot Main:
UInt32 PilotMain(UInt16 cmd, MemPtr cmdPBP, UInt16 launchFlags)
{
ContextType context;
UInt16 error;
context.hasGlobals = launchFlags sysAppLaunchFlagNewGlobals;
if (cmd == sysAppLaunchCmdNormalLaunch)
{ globalContext = context;
error = AppStart(context);
if (error) return error;
FrmGotoForm(ID_FORM_LIST);
EventLoop();
AppStop(context);
return 0;
}
else if (codes snipped...)
I use ContextType to store Global variables and it's huge. That's the
problem. I need to free up the resources when ContextType is not used. I
just don't quite understand how to use MemPtrNew to free the memory.
Thanks for your help in advance.

Palm Powered logo certification
My application is developed in Satellite Forms v5.2, but I would like to try to get the Palm Powered logo certification. According to the certification requirements, all debug options must be turned ON during emulator/simulator testing of our app. However, Satellite Forms requires that all debug options be turned OFF in order to run in the emulator (because of OS calls, I guess) without crashing. So... can a Satellite Forms-developed app be certified under this program?? Has anyone done this? Do you need a special exemption?? thanks, Karen Keefer -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

There are ways you can check if globals are available. I don't know what
they are so you'll have to look it up in the archives or something.
But it sounds like you may not have access to globals and you may want
to consider how to write your app w/o using them.

Re: MemPtrNew / MemPtrFree
George,
How HUGE is your global structure? You should never create nor reference
globals from within the PalmMain function. You should also keep your use of
globals to a minimum. But any globals you do use in your app can be
created/initialized in your AppStart() function.
MemPtrNew allocates non-movable memory, I believe you can do it like so:
UInt32 *myVar
myVar = (*UInt32) MemPtrNew(sizeof(UInt32));// allocates a UInt32 on the
dynamic heap
*myVar = 1;// set its value
//free the memory
MemPtrFree(myVar);
// note, because this is non moval memory, you should not keep it around
long... if you need to keep something around, try using MemHandleNew,
MemHandleLock and MemHandleFree. Its all in the palm OS reference guide.

I have a problem,
Your basic problem is a lack of C skill. Programming
Palm OS, in many ways, requires skills that left
common use fifteen years ago (it's certainly been
that long since I was paid to write C code on any
other platform). It's worth finding a good book
on C programming and reading the section on strings
carefully.
Or, perhaps better, walk away from C and use one
of the higher level languages such as AppForge,
NSBasic or Java. There are also tools targetted
at specific types of applications.
The detail that has led me to this conclusion are:
typedef struct PacienteStruc
{
Char *Nombre ;
A Char * is not a string in the same sense as
VB or Java Strings. A Char * is a pointer to a
the start of a string in the same way that an int *
is a pointer to an integer.
The structure you've defined has no space in it to
store strings. If each member was defined as
Char Nombre[NOMBRESIZE];, for instance, then it
_would_ have space to store a string.
newRecord.Nombre = Bill;
This sets your pointer to a constant stored in the
application. This doesn't copy anything anywhere
and definitely won't store that name in the database
record. You need to read about StrNCopy, StrNCat,
StrLen and the like.

(I've never used Satellite Forms, but I'd be very afraid of any application that can't run in the emulator with all debug flags turned on.) It is not that simple. The philosophy of RAD tools is to keep the programmer away from low level details, such as memory allocation, or packing strings into database records, or dealing with subtle differences between OS versions, and so on. This is usually done through a runtime library, which behaves as a layer that translates what the programmer wants into low level Palm OS calls, and/or that provides helper functions. The problem is that it is almost impossible to write an efficient runtime library for Palm OS without either calling system use only functions (such as MemChunkNew) or either poking internal OS structures on 68k devices (fortunately, OS 5 provides enough functions to make this unecessary on ARM devices). Both triggers warnings when running with all options on. Another problem is that the emulator/simulator tends to be very suspicious. For example, a RAD tool may provide some sort of exception mechanism. To implement this, you have to write assembler code that crawls the stack up until it finds a handler for the exception. Unfortunately, reading and writing values from a stack frame which is not the officially active stack frame sometimes triggers an illegal memory access if all options are turned on. And there are many other examples. IMHO, the palm powered logo should take the development tool into account, or it will dramatically restrict the number of applications that can pass this certification...

Handling a datebook press
Hi folks, what I want to do is to intercept a datebook hardbutton key press, and handle it manually. If conditions are not met I want to ignore the button press completely, and I'm not sure how to avoid the launch of Datebook, or kill it if it is underway. I've tried using the sysNotifyVirtualCharHandlingEvent and sysNotifyAppLaunchingEvent notifications to detect the press, but both seem to be too late, after the launch of Datebook is already in the queue. So, a couple of questions/comments: Is using a notification the right way to go? If so, have I chosen the wrong notifications to try? I thought that changing the priority of the notification might help, but I couldn't detect any improvement. If I've used the right notifications, what method must I use to kill the app launch event already queued up? Surely it must be possible, but I just can't find a way (I've tried emptyin queues, flushing queuse, enqueuing other events, etc., with no success). Thanks for any assistance.

I do know that you can do that from within the current app, but I'm trying to intercept the datebook press using a 3rd party app. For instance, you are in NotePad, and press the Datebook button. I want my app to intercept THAT press, so I don't have access to the Notepad eventloop where I could handle this. So I thought of using a notification in a separate small app, and it works well at detecting the press, and launching my app if conditions are correct, but if conditions are NOT met it always launches Datebook. I haven't found any return code, or queue clearing function, that will stop the Datebook launch from happening. Does that make my problem more clear, or have I misunderstood your advice.
