I asked this before but it was moved to the desolate forum, i.e Cortex-A5.  This question is a general question on all microchip MCU/MPU.

Okay, and the question is, what system calls would you like to see in an RTOS?

 

I'm looking to implement things like red/write semaphores that you don't usually have implemented.

To where it belongs!

No it isn't - what appropriate to an MPU (Cortex-A level) is highly unlikely to be applicable to a small MCU like an 8-bit AVR!

 

 

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

I'm also running it on the UC3.

Would a malloc that runs of the task stack be worth implementing?

So guys, I've had a break from programming, however I would still like feedback on API calls you would like to see integrated into a RTOS?

For example, I implemented a Semaphore PI for read/writes!
