Hello
I am looking advice for project based on RTOS (small projects). I have been searched on this site http://www.freertos.org/ . I have experience with microcontroller , LED , LCD Motor ..etc What Can I do with these devices to learn RTOS. If I have ARM M0 and Some LED'S on evaluation board. Is it possible to write program for LED? I just want to know what type of RTOS project we can do with this devices ?

 

Sure it's possible to write a blink led program using the RTOS multi-threaded style of programming instead of a bare metal state machine on a controller.
Why are you interested in writing applications for them?

Once you go to a multi-threaded approach, things can become more complex until you wrap your head around the issues but you won't see these problems with a blink led program.

Using a RTOS system is complete overkill for a simple one-threaded program with an LED as a simple display. If the LED is used in a complex manner like an IR transmitter task used to send data generated from another controller DAQ task then maybe a RTOS might be useful.

My #1 point of advice:
Read those downloaded books and sample programs.
