Structure de base
Le code du Raspberry Pi se compose des parties suivantes :
- Importer les bibliothèques nécessaires
- Initialisation et configuration
- Boucle principale : s'exécute de manière répétée, infiniment
- Gestion des exceptions (optionnelle)
- Fin du programme
Les deux squelettes de code :
- Détourner du contenu fonctionnel ordinaire sans implication de logique, garantir l’adaptabilité, simplifier la maintenance.
# Import Required Libraries
# Initialization and Setup
# Perform one-time setup tasks here
try:
# Main Loop
while True:
# Main code logic goes here
pass # Replace with your code
except KeyboardInterrupt:
# Handle Ctrl+C interruption
print("\nExiting the program.")
# Program Exit
# Add any cleanup tasks or final actions here

finally:

Exemple de code Raspberry Pi
Voici des exemples de codes qui font clignoter une LED.
- Exemple de code pour le squelette n°1
# IMPORT REQUIRED LIBRARIES
import RPi.GPIO as GPIO
import time
# INITIALIZATION AND SETUP
# Set the GPIO mode to BCM
GPIO.setmode(GPIO.BCM)
# Define the GPIO pin for the LED
LED_PIN = 17 # Use GPIO pin 17
# Set up the LED pin as an output
GPIO.setup(LED_PIN, GPIO.OUT)
try:
# MAIN LOOP
while True:
# Main code logic goes here
# Turn on the LED
GPIO.output(LED_PIN, GPIO.HIGH)
# Wait for a second
time.sleep(1)
# Turn off the LED
GPIO.output(LED_PIN, GPIO.LOW)
# Wait for a second
time.sleep(1)
except KeyboardInterrupt:
# Handle Ctrl+C interruption
print("\nExiting the program.")
GPIO.cleanup() # Clean up the GPIO

# Cleanup GPIO on exit
