Jetson-GPIO Library Update

Lately, NVIDIA has published a GPIO library based on Raspberry Pi GPIO library. This library comes pre-installed on the module. On this blog post, we will patch that library to activate DSBoard IIO pins. This blog post applicable for DSBOX-NX2 and DSBOX-N2.

First of all download updated version of this library from our GitHub repository.

• cd

• git clone https://github.com/mistelektronik/jetson-gpio

You can use this library directly but there could be a conflict between pre-installed library. To solve this copy "lib/python/Jetson/GPIO/gpio_pin_data.py" file over the pre-installed library.

• sudo mv /usr/lib/python2.7/dist-packages/Jetson/GPIO/gpio_pin_data.py /usr/lib/python2.7/dist-packages/Jetson/GPIO/gpio_pin_data_backup.py

• sudo mv /usr/lib/python3/dist-packages/Jetson/GPIO/gpio_pin_data.py /usr/lib/python3/dist-packages/Jetson/GPIO/gpio_pin_data_backup.py

• cd jetson-gpio

• sudo cp lib/python/Jetson/GPIO/gpio_pin_data.py /usr/lib/python2.7/dist-packages/Jetson/GPIO/gpio_pin_data.py

• sudo cp lib/python/Jetson/GPIO/gpio_pin_data.py /usr/lib/python3/dist-packages/Jetson/GPIO/gpio_pin_data.py

After these commands, you can use IIO pins using the library. First two commands added for backup reason; so anything goes wrong you can find original files.

On the table below you can find IIO GPIO numbers and names to use inside the library.

Thanks for reading.
