Instead of reading them out, one sets the row value and corresponding column values are returned through r1-r8. +* On my keyboard, the keypad and program key have dedicated pins. Since row 12 had no mapping in the physical matrix, there's a code override injects the keypad and program pins to the first two bits in the matrix. +* I've experimented with debouncing approaches. The current setting delivers a snappier feeling than Kinesis's factory default for me. |
