Hello, Is there a way to pullup port 26 and 27 with an instruction like: pinMode(26,INPUT_PULLUP); pinMode(27,INPUT_PULLUP); It seems that it doesn't work. Perhaps it's not possible to pullup via software all the ports?

Thanks

Only the "change notification" pins (ones marked CNx) in the data sheet / manual have internal pullups. On the UNO32 that's pins 10, 11, 12, 13, 14, 15, 20, 21, 25, 36, 37, 39, 40, 41, 42 and 44.
