Well, this is going to be fun. What I'm about to do is to figure out what combination of pins gives us what letter. Please see my other blog: How to use a PS/2 Keyboard Encoder with interrupts. The object is the connector at the bottom of the unit.
So we have two sets of 13 fingers, so we need a 13x13 table. I will say this starts at the left and goes to the right, with the first group on the left I will call columns, and the second group will be the rows. I will probe the fingers starting at c1 & r1 and see what character shows up and put it in the table. So which keys do I need? First I need all the numbers 0 through 9 they are located on the top row. I need the Enter, the Backspace, and a key to be the ALPHA key maybe the A.
Please note I was going to do this a while back, Now I need this!! So Next Update will have the MAP
