MemMove or not ?
Hi,
Based on your experience and PalmOS source code, what's the fastest in ARM :
- MemMove
- or
void my_memmove(UInt8 *dst, UInt8 *src, UInt32 size) {
while (len--)
*dst++ = *src++;
}
Thanks
Chris

T5 questions
1) Is it posible to debug on the device (with CW9.3)? I have tried, but not been successful yet. 2) What are the keys for the 5-way navigator on the T5 sim?

Re: T5 questions
Hello, Neil! There's a text file accompanying the T5 Sim, which says the keys are the arrow keys, like the ones for Treo 600 Simulator, but that's incorrect. One of the text or PDF downloads in the Pluggedin program (where the T5 Sim download is) lists the correct keys - Alt+Enter for Center, Alt+Left/Right/Up/Down for navigation. By the way, this is a bad choice of control keys on the designers part - sometimes, unexpectedly, a menu pops up for a second (when you press the Alt key).

Re: Using Records
If you are never going to do anything with the HH data on the PC then
replacing the record is a reasonable option. If you can see that one day you
may want to access and modify the data on PC via conduit and PC application
then replacing is not a good option because it can be a problem to sync HH
and PC changes. If you go the replace route make sure that you remove the
old record instead of deleting it cause DmDeleteRecord leaves the records
header entry for use by a conduit.
To modify the record as per your in-memory example closely follow the
example you posted (unless I don't understand the question).
1. get the handle to record x
2. create a OemiDBRecordType structure pointer to the record using the
handle (OemiDBRecordType* recPtr). You will have to decide the char* or
fixed array size issue for FileName as mentioned by Henk. Allocating fixed
size record storage is the no brainer solution (no record packing an
unpacking required) and it is fine if you won't have a lot of records
otherwise you go variable length record and get the record pointer via an
unpack function. The addressbook and/or the memopad sample apps have
examples using variable length records with packing and unpacking the record
data.
3. Write the data. Assuming fixed size records:
UInt8 newFreq = 50;
/* Vehicle.CH[4].EQ._30Hz = newFreq; */
OemiDBRecordType* offsetPtr = 0; // simple way to get a structure
member offset
DmWrite(recPtr, &offsetPtr->CH[4].EQ._30Hz , &newFreq,
sizeof(newFreq));
4. unlock the record pointer
5. release the record

"Tony Janke" <[EMAIL PROTECTED]> wrote in message
news:[EMAIL PROTECTED]
I am trying to store a data structure in a record and have a few questions.
There seems to be (at least) 2 ways to store data in a record. You can
either create a new record, and over write an old record with the new copy
that contains the new field values. The other way is to edit the individual
fields that were changed. I'd think it would be much more efficient to
modify only the necessary fields and that brings me to my first question.
The example documentation uses a simple struct:
typedef struct {
char FirstName[20];
char LastName[20];
char PhoneNum[20];
} DBRecord;
typedef DBRecord DBRecordType;
typedef DBRecord* DBRecordPtr;
then when a field (say Last Name) is changed, a simple:
(MemHandle) h = DmGetRecord(gDatabase, index);
if (h) { // could fail due to out of memory!
DBRecordType * p = (DBRecordType *) MemHandleLock(h);
// write only the changed fields of record instead of the whole record
Err err = DmWrite(p, OffsetOf(DBRecordType, LastName), "Knopp", 20);
MemPtrUnlock(p);
DmReleaseRecord(gDatabase, index, true);
will replace the old last name with the new one.
My structure is as follows:
typedef struct{
UInt8 _30Hz;
UInt8 _60Hz;
UInt8 _120Hz;
UInt8 _250Hz;
UInt8 _500Hz;
UInt8 _1000Hz;
UInt8 _2000Hz;
UInt8 _4000Hz;
UInt8 _8000Hz;
UInt8 _16000Hz;
} EQFreq;
typedef UInt8 FilterType;
enum FilterType{HighPass, LowPass, ByPass};
typedef UInt8 MixerType;
enum MixerType{NONE, A, AB, AC, ABC, B, BC, C};
typedef UInt8 StereoModeType;
enum StereoModeType{LEFT, RIGHT, STEREO};
typedef Char* FileName;
typedef struct{
Boolean STEREO; // Stereo Linked?
EQFreq EQ; // 10-band EQ settings
MixerType MIXER; // Mixer controls
FilterType FILTER; // Filter type (HP/LP/BP)
UInt8 VOLUMELEVEL; // Volume Level
UInt16 FILTERFREQ; // Filter Fc
UInt8 DELAY; // Delay in 100's of uS
Boolean MUTE; // Is Muted? T/F
Boolean SOLO; // Is SOLO? T/F
} ChannelAtt;
typedef struct{
Char* FileName;
ChannelAtt CH[6]; // Channel 0 used for Tune Mode
StereoModeType StereoMode; // Channel mode, Left, Right or Stereo Link
} OemiDBRecordType;
To modify the 30Hz filter value for say channel 4, I would normally do a:
OemiDBRecordType Vehicle;
UInt8 newFreq = 50;
Vehicle.CH[4].EQ._30Hz = newFreq;
Currently, I have a global variable (Vehicle) that I can access in any
function, but I wanna change that and store the data in records. How would I
change that value using the DmWrite function? my goal is to use each
record as a "file" so that the user can select between different setups by
choosing different records.
Also, while trying to troubleshoot my code, I am using the simulator to look
at my Database and record data. I can see the database and the records I
create, but I don't know how to decipher the data I see in that record.
When I assign a value to a variable and write that value to the record, I
see that some of the record values change but don't know how to interpret
those changes to verify they are correct. How do read these values and is
there a way to see a database and record during debugging?
thanks in advance!

Creating Debug version using CodeWarrior
Hi,
Creating a new CW project creates 2 targets: Debug and Release. How do I add
debugging code to the Debug target? Is there a symbol defined ("DEBUG"?) that
I use, or is it a matter of having one file (that defines "DEBUG") included in
one target and not in the other? What are my options?
I want to do something like this:
#ifdef DEBUG
x = 1;
#else
x=2;
#endif
Thanks,
Peter

Your answer really helps. Probably it's not a good idea to use PalmOS for the project because access to it is too difficult.

I'm sure of all the possible licensees, Dell is the one LEAST likely to not do it b/c of licensing fees and minimum sales contracts. Why would using AMD processors put a strain on dell's relationship with m$? I agree that much of Dell's success can be measured because of lower OS rates for windows from m$. However, the OS cost related to the hardware cost in PDAs and phones is much lower so I don't think m$ can put that much pressure on Dell. They could shave at most a few dollars off of the price. If you don't like Dell than pick gateway or HP. I dont care. I was just making a point that palmsource needs to license their OS to whoever wants to build devices around it. PalmOne clearly hasn't sworn its allegiance to palmSource given some of its statements in the past 6 months. I would bet anything at least one of those 3 companies came to palm to licenses the OS and was turned down because Palm wanted to protect its current licensees. Protectionism doesn't work. m$ primarily won the desktop OS war because it stayed out of the hardware business and licensed it's OS to anyone who wanted to build a whitebox. They are approaching the embedded/PDA market the same way. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Re: Creating Debug version using CodeWarrior
I've set up debug and release macros for my project in CodeWarrior
through precompiled headers. You create two precompiled headers, then
in the target settings, specify the precompiled header belonging to
the target. Within your precompiled headers, you can specify whatever
macros you like, and they will only apply to the relevant target. Of
course, you need to setup a file to generate these precompiled
headers, and you should set these per target so that each target only
includes the relevant one.
This will amount to the same thing as simply including a normal header
based on the target, but has the benefit of not needing to process the
header over and over.

RE: FormType and database
The problem in OS 5 is due to the shaadow structures... What you get back from FrmNewForm is not the form but rather just the shadow of the real native ARM form. Some of the form information is shadowed to increase compatiblity of apps that access those structure elements directly, but not everything. The actual native form type is not different - just native and hidden from you (old apps with old form resources still work right). So instead of using FrmNewForm, try building your own myFormType that matches the OS FormType structure element for structure element. Fill that out yourself and FrmDrawForm it by casting it to a FormType. There is an example in the kb.palmsource.com for bitmaps, but the theory should work the same. -Ezekiel * Subject: FormType and database From: "tut.by" <[EMAIL PROTECTED]> Date: Tue, 9 Nov 2004 11:10:26 +0200 X-Message-Number: 1 Hi.

How to detect if a menu is open
Hi, I am in the process of developing a little clock that draws to the screen via a buffer. No problems up to here However, when the user opens up the menu, it gets overdrawn with the data that comes in from the buffer at a nilEvent in the forms event handler. I would now like to know how it is possible to determine if the menu is open! Or is there another way to stop this distortion? I already googled a bit in my documentation that came with the SDK. I wanted to use the menuOpen and menuClose event pair, however the documentation says that the menuClose event does not work at all! So this concept wont work..

RE: How to detect if a menu is open
You need to look for winenter and winexit events to see if something else (the menu) is active on the screen. If so, you stop drawing. -- RA Moynihan Sent from my Treo -Original Message- From: Tam Hanna Date: 11/10/04 1:25 pm To: Palm Developer Forum Subj: How to detect if a menu is open Hi, I am in the process of developing a little clock that draws to the screen via a buffer.

CW 9.3 debugger does not fully scroll to breakpoint
Since I moved to CW 9.3, I noticed that most of the time (if not all), when I stop on a breakpoint while debugging, I have to scroll down the debugger window to get to see the breakpoint line. Is it just me or is this a bug (or undocumented feature)? -- Luc Le Blanc -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Hi,
Creating a new CW project creates 2 targets: Debug and Release. How do I add
debugging code to the Debug target? Is there a symbol defined ("DEBUG"?) that
I use, or is it a matter of having one file (that defines "DEBUG") included in
one target and not in the other? What are my options?
I want to do something like this:
#ifdef DEBUG
x = 1;
#else
x=2;
#endif
Thanks,

RE: CW 9.3 debugger does not fully scroll to breakpoint
Luc, I have that as well, would be nice if the window opens with the breakpoint right there. I believe that 9.2 had the same.

Treo 270 API for SMS/EMS
Hi, I have been googling the web for information about the Treo 270 APIs/SDK with no luck. I would like to know if it is possible to create a Palm OS application that requests with an SMS (Short Message Service) and receive a reply with an EMS (Enhaced Message Service). The idea is to request for some information using an SMS and receive the answer as an EMS, including a graphic. I could not find any SDK documentation, nor the SDK itself. I know the device is not the latest one, but it serves the proposal the application will provide. Any help about url's for information and (desirable) SMS/EMS sample are welcome Thanks very much!

Re: How to detect if a menu is open
An easy way to do this without using globals or flags is to check if the current window is the active form's window when you want to draw something. If they are not the same, don't draw to the screen. I found this easier and just as effective as trapping winEnter/winExit events.
