Hi
I am able to control the Pin 7 using the example in getting started.
The example uses pin 7 as 337 and works fine. (echo 337 > export)
What are the values for the other gpio pins. how to use pin 18 for example? (echo ??? > export)
Thanks much Kenny

What processor is driving the 40 pin GPIO. ATSAMD21? Or Celeron processor via some electronics?

Question re: 40 pin GPIO.

When I pull the pin down is it High Impedance or Open Drain. My preference is Open Drain if possible

Thanks
