PJON is really great library. I build my own simple protocol based on it for my smart-home solution. It works great for Arduino <-> Arduiono communication, but actually I need to connect all my Arduino devices to central Raspberry. I thought the best way to do this could be to connect every Arduino to one digital pin on Raspberry and talk to them via SoftwareBitBang.
Is there any significant problem with SBB on Raspberry? Or is only about playing with Timing.h constants?
Any other idea how to connect all my Arduino devices to central Raspberry Pi?
