OSA - RTOS for PIC controllers

[tester]

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.

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

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.

and i compiled the file "lights_ccs16.c" from the same folder "osa" i did not change any thing i downloaded and compiled as it is..... now i am getting this message as shown in the attachment...

actually i am new to this concept OSA.... i started reading this topic from yesterday evening. i am very much interested with this.. i tried several ways yesterday.........

please help me in successfully compiling this and running osa in my PIC...

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.

Thanks for your reply.

Do this OSA work for my version of CCS? I will try and update to you when I reach my home.

I would like to ask you to support CCS for dspic (pcd) the idea of it?

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 ?
