if you choose to implement a software UART ("bit banging...") here is where you can get a kick start:

if you choose to implement a software UART ("bit banging...") here is where you can get a kick start as I have often said: "reference code is totally worthless unless you could write the code yourself if you had to" reference code never (I wish I could say 'rarely') works and if you do not have the ability to write whatever yourself, you will be absolutotally lost with reference code.
