Caractéristiques

16 niveaux de gris

il y a 2 versions

matrix OLED v1.0
96 × 96 pixels
Pilote SSD1327

matrix OLED v2.1 *utilisé pour nos tests
128 × 128 pixels
Pilote SH1107G

Les deux versions partagent la même bibliothèque qui de base était conçu pour la version 1.0

Communication

Port I2c ✅

Support

Supports both Normal and Inverse Color Display
Supports Continuous Horizontal Scrolling

Pilotes (Drivers)

OLED Display: LY120-96096
Driver I2C:
v1.0 SSD1327Z
v2.1 SH1107G

Voltage

Operating Voltage: 3.3~5V

Mise en route (Setup)

connecter au port I2c
installer la bibliotheque
github -> https://github.com/Seeed-Studio/OLED_Display_96X96

il faut aussi la bibliotheque arduino wire.h

veuillez adapter le code selon la version OLED utilisée
v1.0 -> SeeedGrayOled.init(SSD1327);
v2.1 -> SeeedGrayOled.init(SH1107G);

Code Hello World! (u8g2)

Bibliotheque u8g2 128 × 128 pixels

library of u8g2 (Monochrome graphics library supports OLEDs and LCDs)

Grove Base for XIAO
XIAO-ESP32S3
OLED Display 1.12 - Port I2c✅

mais il n'écoute pas x,y n'est pas exécuté, on demande de faire 0,24 mais il fait 0,0

#include <Arduino.h>
#include <U8g2lib.h>
#include <SPI.h>
#include <Wire.h>

U8G2_SH1107_SEEED_128X128_1_SW_I2C u8g2(U8G2_R0, /* clock=*/ SCL, /* data=*/ SDA, /* reset=*/ U8X8_PIN_NONE);

void setup(void) {
  u8g2.begin();
}

void loop(void) {
  u8g2.firstPage();
  do {
    u8g2.setFont(u8g2_font_ncenB10_tr);
    u8g2.drawStr(0,24,"Hello World!");
  } while ( u8g2.nextPage() );
}

voici une autre version avec u8x8✅
Oui ceci fonctionne, juste le texte petit, mais à l'emplacement prévu
Autrement il affiche, ensuite il efface l'écran, ainsi de suite

#include <Arduino.h>
#include <U8x8lib.h>
#include <Wire.h>

// Remplace U8G2 par U8X8
U8X8_SH1107_SEEED_128X128_SW_I2C u8x8(/* clock=*/ SCL, /* data=*/ SDA, /* reset=*/ U8X8_PIN_NONE);

void setup(void) {
  u8x8.begin();
  u8x8.setPowerSave(0); // Active l'affichage
  u8x8.setFont(u8x8_font_chroma48medium8_r); // Choisis une police compatible U8x8
}

void loop(void) {
  u8x8.clearDisplay(); // Efface l'écran
  u8x8.drawString(0, 24, "Hello World!"); // Affiche le texte à la ligne 24, colonne 0
  delay(1000); // Petite pause
}
