Fisherworks reacted to robertoj in Orange Pi Zero 3 GPIOOk. I got one output pin to work. 😀
This is how to do it in OrangePi Zero 3, pin 8 PH2:
In Bash as root:
# addgroup --system gpio
# chown root:gpio /dev/gpiochip0
# chmod 660 /dev/gpiochip0
# nano /etc/udev/rules.d/61-gpio-tools.rules
{add line SUBSYSTEM=="gpio",KERNEL=="gpiochip*", GROUP="gpio", MODE="0660"}
# usermod -a -G gpio myusername
# apt install python3-dev
# reboot
In a new folder for your Python script, as normal user:
$ python3 -m venv .venv
$ source .venv/bin/activate
$ pip install gpiod
Create script (example in https://pypi.org/project/gpiod/ with one fix):
$ nano blink_pin.py
import time import gpiod #needed in example from gpiod.line import Direction, Value #Calculating PH2 "line" number #H=8 #2=2 #line=(8-1)x32+2=226 #also shown in https://github.com/rm-hull/OPi.GPIO/issues/79 LINE = 226 with gpiod.request_lines( "/dev/gpiochip0", consumer="blink-example", config={ LINE: gpiod.LineSettings( direction=Direction.OUTPUT, output_value=Value.ACTIVE ) }, ) as request: while True: request.set_value(LINE, Value.ACTIVE) time.sleep(1) request.set_value(LINE, Value.INACTIVE) time.sleep(1)
Run script:
$ python3 blink_pin.py
When done working with your project:
$ deactivate
Pin 8 PH2 turns ON and OFF 😄
I haven't tested the other pins yet
