==== 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 <USER>'' + reboot

Suivi de l'installation proprement dite :

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

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

==== Serial Output ====

<code c>
void setup() { 
  Serial.begin(115200);
  while (!Serial) continue;
  Serial.println("Ready.");
} 
void loop() { 
}
</code>

Suite illogique des pins GPIO

GPIO-1 en OUTPUT -> conflit avec sortie serial
<code c>
#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);
  }
}
