OSA - RTOS for PIC controllers
PostPosted: Mon Jun 29, 2009 9:01 am     Reply with quote

Hello!

RTOS OSA is now ported to CCS (for PIC16s and PIC18s). This is free cooperative RTOS with all source code included. You can download it here: http://wiki.pic24.ru/doku.php/en/osa/ref/download/intro

OSA supports:
- priorities;
- timers (delays, timeouts, user timers);
- binary and counting semahores;
- messages;
- queues;
- flags.

On-line manual is here: http://wiki.pic24.ru/doku.php/en/osa/ref/intro

I hope OSA will be usefull for someone.

Best regards, Victor Timofeev

Great! Is version 3.249 able to compile it? I tried and got some errors but did not investigate why yet.

I tried only with version 4.084.

What type of errors? What does your program do? Is your project created correctly?

Bug fixed for PIC18: internal function _OS_InitDelay worked incorrectly. It is recommended to download new version 90716: http://wiki.pic24.ru/doku.php/en/osa/ref/download/intro

osa.h
PostPosted: Mon Aug 10, 2009 10:45 pm     Reply with quote

I tried to run a simple code shown below. By copying osa.h and OSAcfg.h in the compilation dir, but I cannot successfully compile it.
Code:

#include <16F877A>
...clock and misc....
#include <osa.h>
 
void main (void)
{
    OS_Init();
    OS_Run();
}

If I run this plain program it is showing an error as " # a device must be included....."

Across this in the file osa.h the error is coming
Code:

#if !defined(OS_SMSG_TYPE)
#define     OS_SMSG_TYPE    unsigned char
#endif

Could you please give me any fully functional program that works with CCS compiler version 4.084 please Cool Rolling Eyes Rolling Eyes

First: it is wrong to copy osa.h into the project directory. This file should be stayed into OSA directory.

Second: did you create your project correctly?

Look at the OSA last version:
Path "osa\test\" contains test projects (projects created in MPLab).
Path "osa\example\ccs" contains working example for LED controlling.

Error "File can't be opened" occurs because of osa.h is included with <> braces, so it is supposed that this file located in the include path, not in project path. See MPLab menu "Project\Build options\Project\Directories" list for "include path search". There should be two paths: path to your project directory and path to osa.c file.

All project settings (e.g. paths) suppose that project placed into c:\osa\examples\ccs (you placed it on the desktop). Move OSA folder into C:\ and try again.

Not now, may be in future. dsPICs and PIC24 are supported by OSA only with Microchip C30.

dear tester it is working fine in V4.023
PostPosted: Tue Aug 18, 2009 1:01 am     Reply with quote

I actually configured the compilation folder to the folder "osa" then compiled an example CCS program "LED xxx"...... it compiled with no errors.

It is working with the simulator. But it did not still work with the real PIC hardware. Today this evening I will try in my home and reply back to you tomorrow.

Can you give me a study guide to add the functions into RTOS ?
