2 types de microcontrolleurs utilisés pour cet atelier: GEMMA M0 et GEMMA V2
Pour le Gemma M0
L'ensemble des infos est disponible en anglais sur https://learn.adafruit.com/adafruit-gemma-m0/overview
Logiciels à installer:
Pour Windows, télécharger et installer les drivers: https://github.com/adafruit/Adafruit_Windows_Drivers/releases/latest
Pour toutes les plateformes:
- installer Circuit Python en suivant la procédure: https://learn.adafruit.com/adafruit-gemma-m0/circuitpython
- installer MU Editor: https://codewith.mu/
Vous pouvez connecter votre microcontroleur et lancer MU Editor pour tester votre premier code:
import board
import digitalio
import time
led = digitalio.DigitalInOut(board.LED)
led.direction = digitalio.Direction.OUTPUT
while True:
led.value = True
time.sleep(0.5)
led.value = False
time.sleep(0.5)
