Raspberry Pi Smart Display Module · File : gpio-led-status-indicator.py · Language : Python · Use case : Contrôler une LED de statut via GPIO pour indiquer l'état du système d'affichage.

Python script using the RPi.GPIO library to blink an LED connected to a GPIO pin on the Compute Module 5.

This module requires the Raspberry Pi Compute Module 5 mounted on the Smart Display Module. Ensure the RPi.GPIO library is installed via 'pip install RPi.GPIO'. Connect an LED with a series resistor to GPIO pin 17 (BCM) and ground. Run the script with sudo python3 gpio-led-status-indicator.py for GPIO access permissions.
