Tiny os for avr microcontrollers

[anoop kr]

Hai i am using ATmega32 microcontroller.In that MCU can i port any OS .I heard about RTOS.But some peoples says that it can port only in 32bit controllers.Is this true..?.If its possible for 8 bit controllers which is the best one that can use..?.I am using ATmega32 controller.Is there any RTOS that possible for ATmega..? Please help....:???:

Free RTOS is ported for avr micro's, however for 32K flash and 8 bit micro's it is usually better to make a custom simple scheduler.

Go to Pumpkin: Salvo, the RTOS that runs in tiny places - SALVO RTOS can really fit into extremely small uP. I've seen projects with Tiny25 with several tasks running. My own experince is that this is the best RTOS for small uP - extremely compact and fast, well documented and rock stable

Hmm as far as I know salvo is not free, am i right?

actually it's not true - there is SALVO Lite which is totally free. It has only some limitations like - maximum number of tasks, maximum number of events, semaphores. And of course you don't get the source code - only the library. Notice that this library is 100% functional and will never expire. One tip - if you're student you can claim for academic version which is quite cheap (~150$). You should not hesitate to use SALVO RTOS, personally for me the impact of introducing SALVO in my projects was smashing - the feeling was just like moving from assembler to C.
