Hello all,
I have just written some 8051 code to play a message from theISD2560 speech chip. It is just a subroutine. I hope that some of you out there can tell me if Im on the right track. Please note that P1 is connected to the address lines and P2 pins are connected to the 3 control lines. Code is commented. The project is a maze robot car. Thanks a million.
