Example using embassy to asynchronously use the i2c-bus and operate 2 devices in asynchronous mode:
- Pressure sensor ms5611 is read in one task and sends the data via
- in another task, a button is evaluated. Each press increments a counter and sends it via a channel
- a task updates an ssd1306 display (128x32 pixels) by receiving the pressure sensor measurement and button counter via channels and displaying them
- Rust
- ESP-IDF
- An ESP32-C3 development board
- ms5611 with i2c interface
- ssd1306 display with i2c interface
- I2C bus wiring: SDA: GPIO 6, SCL GPIO 7
- Button: Wiring GPIO2, GND
- Clone the repository:
git clone https://github.com/your-username/esp32c3-display.git
cd esp32c3-display- Install the dependencies:
rustup target add riscv32imc-unknown-none-elf
cargo install espflash- Build the project:
cargo build- Flash the firmware to the ESP32-C3 board:
cargo run-
Connect the display to the ESP32-C3 board according to the pinout in the documentation.2. Connect the display to the ESP32-C3 board according to the pinout in the documentation.
-
Start the board and check the display.3. Start the board and check the display.
