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

Thanks for your reply.
I got it all is now working fine.
Some how I missed the the Linux GPIO list.
It must be my age I’m 82 years old.
Thanks again.

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
