Help, multiple i2c buses esp32

[yhomer]

Hello, I want to use an i2c oled screen through the GPIO32 and GPIO33 ports of the esp32 and leave the GPIO21 and GPIO22 ports free for other i2c connections, but I can't get the screen to show an image, this is my code:

Code: Select all

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 32
#define OLED_RESET    -1
#define SCREEN_ADDRESS 0x3C
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
#define I2C_FREQ 400000
#define SDA_1 21
#define SCL_1 22
#define SDA_2 33
#define SCL_2 32
TwoWire I2C_1 = TwoWire(0);
TwoWire I2C_2 = TwoWire(1);


void setup() {

  I2C_1.begin(SDA_1, SCL_1, I2C_FREQ);
  I2C_2.begin(SDA_2, SCL_2, I2C_FREQ);

  if (!display.begin(SSD1306_SWITCHCAPVCC, SCREEN_ADDRESS)) 
  {
    Serial.println(F("SSD1306 allocation failed"));
    for (;;); // Don't proceed, loop forever
  }

}
 
void loop() {

  display.clearDisplay(); 
  display.setTextColor(WHITE);
  display.setTextSize(1);
  display.setCursor(0,0); 
  display.print("I2C Scan por Aaronfix");
  display.display(); 
}
