Pthread.h on ATmega32 micrcontroller

[Etude]

Ok This might be really stupid but I have been finding conflicting answers and getting very confused.

I am trying to program an Atmel ATmega32 using embedded C. This is my first time and I wanted to know if I can use threads in the programming.

Thanx!

IIRC, most microcontrollers don't do threading. You can simulate it using interrupts, I believe.

Quick test of avr-gcc:

me@linuxbox:~$ avr-gcc test.c
test.c:1:21: error: pthread.h: No such file or directory

Looking at atmel's documentation, it's a single cpu. If you want to do multi-threading you'll need to write or obtain a multi-threading operating system for the atmega328. The only operating system for the atmega328 I see in this wiki article is BRTOS, which is apparently free (MIT license).

It's also possible that your atmega328 came with software that included a multi-threading operating system.
