Re: sending the charcter by keyboard and displaying in the l
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).

Re: sending the charcter by keyboard and displaying in the l
Which compiler u use? (what do you mean dll???)
I have C code for PC keyboard, I have too much work right now so I always forgot to upload file when I came home late, sorry (hope I'll remember today).
hello sir,
i am using the keil compiller for my programming.
the dll(dynamic link lib) i mean is by which i do the simulation using the pc itself without using the real lcd for testing my codes.like wise i need a dll for the 4x4 keypad matrix.
thank u
