Hi,

Adam Chapweske provides a lot of useful information (in my opinion) on PC keyboard and mouse interfacing. The information is PIC based but the general purpose information he provides would be useful for any type of microcontroller (again, in my opinion).

interface 8051 with keyboard using serial port.

keyboard will not send ascii code. Convert the code send by keyboard to the ascii code.

Then send it to LCD

u can do it easily
