How are the leds wired? #2

Closed baruch closed 9 years ago

The CC/CV signal seems to come from the bottom board, how is it then relayed to the leds? How/who lights up the active led?

The red led at the bottom is controlled by port 11 / PB5. Still need to check if that is not getting driven by the bottom board.

I suspect the two upper leds are controlled through the 74HC595 units, these have 16 bit outputs but only 12 are needed for the 7-segment 4-digit units so four extra bits are available for additional controls.

With the schematics done by flex we now know the full connectivity.
