Do any of the prevailing firmwares support reading or writing a port pin? If so, which firmware and what G-Code command. I have a list of control codes that I downloaded from the reprap wiki that makes no mention of this feature but I have read elsewhere that it may exist.
I have worked with PICS (and quite a few other processors) for many years and am now learning Atmega.(can't wait until my development board arrives) In PICS you have to set a corresponding bit in a TRIS (tri-state) register before you can read or write a pin, is that the same in ATmega? The Atmega1284P looks like an awesome 8 bit controller.
Is there a place where all of the firmware derivatives and versions are compared?
Do you know of any pointers, forums or places that I might visit to learn the ins and outs of ATmega controller development.
Thanks for your help
