Can you check pins 15, 14 in a similar manner.Ok, so checking pin 16, the highest voltage reading I got was 3.3v, most of the time fluttering around 2.1v or so. Not so steady hands. When grounded, it did hit zero.
So, what could be the cause of that leg not getting enough juice? Would it be the resistors? Or something else?
Pins 16, 15 ,14 are all used for the remote control board. I believe all those pins should be pulled up to 5v.
I 'think' the connection is as follows:
(Remote-41) pulled up via RA14
(Remote-40) pulled up via RA12
(Remote-39) pulled up via RA10
The resistors with the purple and gold stripe are the pull up resistors I believe. You should read ~5V on RA14, RA12, RA10 to ground.
You should also read ~5v on the MCU pins that those resistors are pulling up (MCU pin 14,15,16)
