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...
Re: ESP-32 S3 Cannot initialize multiple spi devices (host_id not initialized) PostbySprite»Thu Nov 16, 2023 2:33 am If I read your code correctly, it's not: you're using SPI2_HOST there, not SPI3_HOST. You either need to move your devices to the same SPI host (if your dev...
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 ...

I2C pins on AI thinker board are hardwired to Camera, whereas one complete side is used by CD card, this leaves us only with GPIO0 and GPIO16, I want to use them for I2C communication while still keeping SD card functionality intact, is it possible? thanks Reply Ed Hayes May 4, 2021...
ESP32-S3 拥有 45 个可编程 GPIO 以及 SPI、I2S、I2C、PWM、RMT、ADC、DAC、UART、SD/MMC 主机控制器和 TWAITM 控制器等常用外设接口。其中的 14 个 GPIO 可被配置为 HMI 交互的电容触摸输入端。此外,ESP32-S3 搭载了超低功耗协处理器 (ULP),支持多种低功耗模式,广泛适用于各类低功耗应用场景。
I2C Manager (i2c_manager) is a component that will let code in multiple threads talk to devices on the I2C ports without getting in each other's way. These drivers use a built-in copy of I2C Manager to talk to the I2C port, but you can also use the I2C Manager component itself and...
