1. Installing the Jetson.GPIO Library

The system installs the Jetson.GPIO library by default; this step can be skipped.

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 Manual installation may result in an outdated version.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 username


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

3. Customize the Rule File

3.1 Copying the Rule File


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

3.2 Reloading udev Rules


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

4. Setting the Motherboard Model

Currently, Jetpack 6.1 does not pre-set the motherboard model. Before each GPIO control operation, you need to set the motherboard model in the terminal:


xxxxxxxxxx
export JETSON_MODEL_NAME=JETSON_AGX_ORIN
