+==== 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>
+==== K2000 ====
+[26/09/2014]
+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);
+  }
+}
