Hello,
I am new to PBP and PIC’s but I am trying to learn more about PIC projects. I need to build a PS2 Keyboard with only some of the keys of a standard keyboard, i.e. 24 to 28. I have a little experience with the 16F688 and if possible I would use it again for this project. I think it will communicate through the serial out of the chip.

Here are my questions; Is there any information on the interfacing of a PIC to the PS2 port on a PC. I have read and I believe I understand the scan codes, but what I do not fully understand is the communication to the PS2 port. Is it 9600 baud with 11 bits? Are there examples out there where someone has done this before too? Does the PBP serial I/O commands support this type of communication?

Communicating through the PS2 port seems very interesting and all types of things could be done, if I can get my head round the basic I/O.

Thanks for the help
