Interfacing the at89c2051 microcontroller
Interfacing the at89c2051 microcontroller
(OP)
I would like some help with this. My project is to interface the computer keyboard to the at89c2051 microcontroller(or any other MC) in order to capture 12 different key strokes from the user which then activates 12 separate telephone lines.
I am using chiplab to program the MC, but I would like to know how i can go about programming the MC to do read the inputs and give me an output to activate a certain line.
