Keypad Decoder Sheet

Here is the sheet for the keypad decoder and LED drivers of our keypad board, including Xref references to the MCU sheet. All that is left is the jog wheel and the three illuminated switches that we have added to our board recently, and will need to be driven directly by the microcontoller in order to avoid having to use a fourth AS1113 LED driver (no need to waste 13 LED ports).

I think I’ll make a poster out of that one…
