1. Install Jetson.GPIO library

The system installs Jetson.GPIO library by default, so you can skip this step.

1.1. Automatic installation


sudo pip3 install Jetson.GPIO

1.2. Manual installation

It is recommended to use the automatic installation method. Manual installation may not be the latest version.


xxxxxxxxxx
git clone https://github.com/NVIDIA/jetson-gpio


xxxxxxxxxx
cd ~/jetson-gpio/


xxxxxxxxxx
sudo python3 setup.py install

2. Set user permissions

Allow the current system user to access and use the Jetson.GPIO library: where jetson is the system user name


xxxxxxxxxx
sudo groupadd -f -r gpio
sudo usermod -a -G gpio jetson

3. Custom rule file

3.1. Copy rule file


xxxxxxxxxx
cd ~/jetson-gpio/
sudo cp lib/python/Jetson/GPIO/99-gpio.rules /etc/udev/rules.d/

3.2, Reload udev rules


xxxxxxxxxx
sudo udevadm control --reload-rules && sudo udevadm trigger

4, Set the motherboard model

Currently Jetpack6.2 does not set the motherboard model in advance. You need to set the motherboard model in the terminal before controlling GPIO each time:


xxxxxxxxxx
export JETSON_MODEL_NAME=JETSON_ORIN_NX
