Bonjour. J’ai une carte esp32 mais sans doute trop ressente. Pas moyen de la déclarer dans mon EDI arduino. Si quelqu’un a rencontré cette carte, je lui propose de partager sa galère avec moi. Le led colorée clignote ( et c’est violent ) mais c’est tout.
J’ai installé la bibliothèque esp32 par espressif sans résultat !
Merci de votre attention.
Bonjour,
Je possede l’ESP32-S3 N16R8, je l’utilise avec arduino IDE 2.3.8, j’ai selectionné ESP32S3 Dev Module, j’ai juste testé quelque script, je n’est pas testé la led rgb mais en general il faut utilisé la librairie neopixel je crois, trouvé les bons pins
peut etre ce sketch
/*
BlinkRGB
Demonstrates usage of onboard RGB LED on some ESP dev boards.
Calling digitalWrite(RGB_BUILTIN, HIGH) will use hidden RGB driver.
RGBLedWrite demonstrates controll of each channel:
void neopixelWrite(uint8_t pin, uint8_t red_val, uint8_t green_val, uint8_t blue_val)
WARNING: After using digitalWrite to drive RGB LED it will be impossible to drive the same pin
with normal HIGH/LOW level

Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

Je pense que le problème vient de l’ordinateur car il ne trouve pas le chemin TTY !
Le cordon est bien un USB-c data car avec un uno il me trouve bien le chemin: /dev/ttyUSB0 Serial Port (USB)
EDIT: Aujourd’hui ça marche. /dev/ttyACM0 Serial Port (USB). Ma LED clignote toujours, et j'ai déclaré ma carte en ESP32S3 dev module. Donc je vais pouvoir la travailler…
