Préambule

Installation

Install config sous Linux

Sous Debian 12, lors du 1er test, j'ai reçu ces deux messages d'erreur:

Error Msg: ''ModuleNotFoundError: No module named 'serial'''
Error msg: ''Failed uploading: no upload port provided''

On va donc, d'abord:

''# apt install python3-serial''
''# /sbin/usermod -aG dialout '' + reboot

Suivi de l'installation proprement dite :

Téléchargement :

Download Aduino IDE: [[https://www.arduino.cc/en/software]]
Unzip : ''$ unzip -d arduino arduino[...]''
Launch : ''$ cd arduino'', ''$ ./arduino-ide''

Télécharger AppImage et le chmod +x for all

Configuration pour ESP32 :

Menu File -> Preferences -> Additional boards manager URLs: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
Menu Tools -> Board -> Board Manager... -> search with ESP32, select de most recent version of ESP32 by Espressif Systems, and Install
Menu Tools -> Board -> Esp32 -> ESP32 Dev Module
Menu Tools -> Port -> /dev/ttyUSB0

Test

Menu File -> example -> ESP32 -> ChipID -> GetChipID
Upload: Menu Sketch -> Upload
Menu Tools -> Serial Monitor
Change to 115200 Baud

ESP32 Chip model = ESP32-D0WDQ6 Rev 101
This chip has 2 cores
Chip ID: 11493932

Suite illogique des pins GPIO

GPIO-1 en OUTPUT -> conflit avec sortie serial

#include <math.h>
const float pi = 3.14159;
const int ledPin[7] = {5,18,19,21,3,22,23}; 

void setup() {  
  for (int i=0; i<7; i++) {
    pinMode (ledPin[i], OUTPUT);
  } 
} 

void loop() { 
  for (float ang=-pi; ang<pi; ang=ang+(2*pi/700)) {
    int led = (1+std::sin(ang))*7/2;
    digitalWrite (ledPin[led], HIGH);
    delay(1);
    digitalWrite (ledPin[led], LOW);
  }
}
