My Due arrived today
I Wont rant too much about how rubbish I think it is that you need to push the reset button every time you want to do something..... Since I am migrating from a MEGA2560, this seems like a poor 'bodge'. On the mega, if I wanted to run a sketch a few times, opening and closing serial monitor was sufficient.....
I Digress... Ok. I looked at the schematic, and I see that as you say, 1 set of RX/TX Leds are indeed just wired to pins 72/73 :-
TXL = PA21 = Digital Pin 73
RXL = PC30 = Digital Pin 72
However, the other set of TX/RX Leds are connected to the ATMEGA16U2.
TXL = PD5 = Pin 11
RXL = PD4 = Pin 10
These are obviously supposed to do something when the programming port is in use, mine do not.
Does anyone else have this problem?
