Yes it couold be but it's not possible. I use a WiFi LoRa 32(V3) board and the OLED is hard solded and the connexion are not accessible from the outside. So i need to have a bus for the onboard OLED and another one for the external sensor ...

Thank you. So i modify the beginning of the software :

SSD1306Wire display(0x3c, SDA_OLED, SCL_OLED);
Adafruit_BMP280 bmp(&Wire1); // I2C

void setup() {
Serial.begin(115200);
Wire1.begin(SDA, SCL);
display.setFont(ArialMT_Plain_10);
display.setTextAlignment(TEXT_ALIGN_LEFT);
display ...

Hello, i'm trying to use 1306 OLED with a I2C bus and a BMP280 sensor with another one :

#include <Wire.h>
#include <SPI.h>
#include <Adafruit_BMP280.h>
#include "SSD1306Wire.h"


#define BMP_SCK (13)
#define BMP_MISO (12)
#define BMP_MOSI (11)
#define BMP_CS (10)
TwoWire I2Cone = TwoWire(0 ...

I have a circuit based on ESP32-S3 and i use arduino IDE. I would like to use BMP280 with i2c. The ESP32-S3 contain 2 i2c device. On this circuit one i2c device is used for an OLED and i would like to use the other one for BMP280. So i have to specify the pins used for I2C but i can't understand how ...
