Yes, the I2C bus allows connecting multiple slave devices to single pair of SCL SDA wires. As long as slave device addresses are unique, everything will work just fine: OLED display, LM75 temperature sensor, MPU6050 gyroscope. However, one has to remember that one of the devices can be pol...
When i'm trying to initialize multiple devices, i get the error: spi_master: spi_master_init_driver(200): host_id not initialized ESP_ERROR_CHECK failed: esp_err_t 0x103 (ESP_ERR_INVALID_STATE) at 0x4037d06c file: "src/board/board_spi.cpp" line 35 ...
I2C interface: The ESP32-S3 provides multi-channel hardware I2C, currently using GPIO6 (SDA) and GPIO7 (SCL) pins for the I2C bus. The QMI8658 six-axis inertial measurement unit and LCD touch control chip are mounted on the board. For details, please refer toSchematic ...
