HDLCpr0tocol stack source in C for AVR or others?do you have it?

I do not want to use a hdlc c0ntroller.I want to do it by software,Do you have it?

You will need to read the data sheet for one of the HDLC controllers and understand it very will. For your software implementation, you will not need to implement all the features inside the CHIP HDLC controller because there is a lot of different modes and you have to select on of this modes because the memory space in the MCU will not cover the implementation of the different modes.

Hi Are you after synchronous or asynchronous HDLC. Async HDLC is easier to implement than synchronous. For implementation details on async hdlc refer to "RFC 1549 - PPP in HDLC Framing".

Hi:

Check the AM85C30 datasheet, this chip have built in HDLC SDLC protocol capabilities, it's a good candidate to emulate, but be aware that this chip have also hardware CRC gen-check + SDLC/HDLC framing and management.

ZAnother choice may be Z80SIO with similar capabilities
