Hi,
I wanna use the pins called 38-45 (F0-7) on this PDF:
https://www.pjrc.com/teensy/card4b.pdf
as digital output.
pinMode(38, OUTPUT);
and then a simple digitalWrite(38, ... HIGH/LOW blinker works just fine.
38, 39, 40 and 41 all good but 42, 43, 44 and 45 won't go low. They even stay HIGH when I set them as inputs.
Teensy is not connected to anything else.
Is there anything special withe these three pins?
