[Résolu] Probleme affichage oled 1.54" + ESP32 wroom

International Français
1

salut a tous je reviens vers vous mon projet avec l'esp 32c3 avance à son rythme.

mais j'ai reçus ce jour les composant pour un plus gros projet,

des ESP32-Wroom, un oled 1.54", et d'autres modules

et ça commence mal, le téléversement se passe bien, l'adresse i2c est bonne, mais sur l'affichage quand ça devais afficher "Bonjour", j'avais rien sur la ligne de texte et de la "neige" sur le reste des lignes. (librairie SSD1306 adafruit)

j'ai donc connecté le oled 0.96" et là j'avais le bon affichage (échange à froid sans re-télélversé)

j'ai tenté d'implémenté avec la librairie U8G2lib, mais le téléversement signale des erreurs, j'ai donc repris un exemple adafruit, cette fois j'ai un semblants d'affichage avec un texte qui (défile rapidement fond blanc texte noir)

et j'ai des lignes alterné blanc et noir. quand je remet l'oled 0.96" j'ai une belle image avec le logo adafruit

le code utilisé (trouvé sur ce forum) :

#include <Wire.h>
#include <SPI.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels

// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
#define OLED_RESET     4 // Reset pin # (or -1 if sharing Arduino reset pin)
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

void setup() {
  Serial.begin(115200);

  // SSD1306_SWITCHCAPVCC = generate display voltage from 3.3V internally
  if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) { // Address 0x3D for 128x64
    Serial.println(F("SSD1306 allocation failed"));
    while (1); // Don't proceed, loop forever
  }
  Serial.println(display.width());
  Serial.println(display.height());

  for (int i = 0; i < 128; i++)
    for (int j = 0; j < 64; j++) {
      display.writePixel(i, j, 1);  // Mettre 0 si rien ne se passe
      display.display();
      delay(50);
    }
}

void loop() {

}

auriez vous une idée du problème ?

J'ai trouvé, c'est pas un SSd1306 mais un SSD1309, avec la bonne librairie ça Fonctionne
