For a custom designed keyboard I want to use a PIC to do the key scanning (8x12 matrix) and connection to an AT Type PC via the PS2 Port. Has somebody got a tip where I can get hold of some basic routines that need only minor modification and adaption? (This question might have been asked on the list, but I have not been on for some time. I do not want to re-invent the wheel.)
