Can anyone help me get myself out of a sticky situation? I need to write Hisoft C code to implement an AN555 style interrupt driven UART. Project deadline was Friday (21). Web access is a bit limited just now so I can't check the Hisoft site for anything. Failing this has anyone massaged AN555 code into Hisoft asm format so I could link it to my C? Pretty please....
