Voltage levels of 40-pin GPIO

Hi @garysims
Could you please share with this python script?
I’m trying to control the GPIO with python-periphery, but it doesn’t work. What do you call your GPIO? Pin no (7, 12…) or Linux GPIO (337, 338…).
I tried:
g7 = GPIO("/dev/gpiochip0", 7, “out”)
g7.write(False)

But as I said pin 7 does not change state.
Thank you in advance!

Edit: I solved it. My mistake was that I used the number of pins instead of the number of lines, when I checked the number of lines with gpioinfo it works ok. Do you have a list with pins - gpiochipNr & lineNr for X86J4105 or know when to check it ?

Edit 2: GPIO pins not responding in code - #2 by zerrofour4
