Hello, I need some help. Could someone explain how to use the ports in asm? More specificly what is the port address and what would I put in for xxxx to make both lines active and both lines inactive. Do i need to load this information to a register first? ld A, xxxx ld C, port address out (C), A Or could I just use Out (port address), xxxx Any help would be appreciated. -Michael P.S. A radio link would be really cool :)
