Hi,
I want to implement a simple, low data rate (1200-2400baud) MSK communication between 2 tiny AVR. (the carrier can be anywhere between 9KHz and 20KHz)

Can you provide some C source code for MSK software modulation/ demodulation?
I want to use only the controller without other active components or circuits.

Thanks in advance,
Best Regards,

HI

8 bit AVR will find it hard to process FSK or MSK data modulated carrier - try to use AVR32 bit or ARM cortex (M3)

Basically you will need to decode A bi-phase signal using DFT algorithm

Google DFT & Grotzel to learn more

Go to TI site and search for MSP430 there is an fine application note for modem design using FSK and code written in C language

All the best
