Is there somebody using a RTOS in his own application ?

What RTOS ?

RTOS means Real TIme Operating System. Some of ST third-parties develop some (ex: CMX, ...). You can have information on their Internet site.

I know what does RTOS mean...

I made the question because I need REAL data about the requirements of RAM and ROM.

I want to know if an RTOS like CMXTiny+ or uC/OS-II is usable in my low-cost system (384 bytes RAM, 8K Flash)...and wich of them you suggest.

I need only the multi task management feature.

Thanks,

Patrik

Have a look at embOS from Segger

http://www.segger.com

They have also given the resource and performance data for ST7 on following link

I found some minimal RTOS:

(Nilsen Elektronikk as )

- eXtreme Minimal Kernel

they aren't ported to ST7 yet and are free.

Another possibility is uC/OS-II that is available for ST7.

I have written a small multitasking engine for the Cosmic C compiler.

You can have up to 254 tasks, (well, not in reality as you are limited by RAm available).

I have implemented mutexes and basic semaphores.

I have attached it....

Good Luck !!
