HW: Serial TX and RX used for col driver on C2 Board #5

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

Serial lines are needed for communication with host pc.  Currently they are 
used for the 4 column driver inputs.

Need to reshuffle routing or add counter chip to circuit.

I am trying to save INT0 for MODE, this is a HW interrupt pin.

The 4 char seven segment LED display has a serial interface so it would be nice 
to have serial available to the proto area.

Break out as many (or all) as you can.
