Anyone here has experience making a PIC based pointing device that can interface with the PC using PS/2 mouse port? Can I have a look at an example of the codes and circuitry?
I'm working on creating a prototype of a new pointing device, just as a uni project, and hoping to make it easily usable through PS/2. If not I have to resort to either making a serial port mouse, or make a VB program that reads from a serial port and draws on a picbox on form, some kind of pointing simulation. I hope not to resort to that though. I really hope to make a working pointing device that acts like a mouse, but using entirely different pointing method, one when I can demo, I can just plug into the PS/2 port of the PC and use.
I'm just looking for codes on how to send data into the PS/2 port of the PC to move the cursor. The programming part for pointing method concept, those I have in mind already how to get by. It's just the interfacing with the PC to move the cursor, detect button presses etc2.
Preferably in any C or Assembly.
Just an example to get me started. most of the stuff I googled out give no clue.
