| Overview |
| ******** |
| |
| M5StickC PLUS, one of the core devices in M5Stacks product series, is an ESP32-based development board. |
| |
| M5StickC PLUS features the following integrated components: |
| |
| - ESP32-PICO-D4 chip (240MHz dual core, 600 DMIPS, 520KB SRAM, Wi-Fi) |
| - ST7789v2, LCD TFT 1.14", 135x240 px screen |
| - IMU MPU-6886 |
| - SPM-1423 microphone |
| - RTC BM8563 |
| - PMU AXP192 |
| - 120 mAh 3,7 V battery |
| |
| Some of the ESP32 I/O pins are broken out to the board's pin headers for easy access. |

| |
| Before powering up your M5StickC PLUS, please make sure that the board is in good |
| condition with no obvious signs of damage. |
| |
| System requirements |
| =================== |
| |
| Prerequisites |
| ------------- |
| |
| Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command |
| below to retrieve those files. |
| |
| .. code-block:: console |
| |
| west blobs fetch hal_espressif |
| |
| .. note:: |
| |
| It is recommended running the command above after :file:`west update`. |
| |
| Building & Flashing |
| ------------------- |
| |
| Build and flash applications as usual (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: m5stickc_plus |
| :goals: build |
| |
| The usual ``flash`` target will work with the ``m5stickc_plus`` board |
| configuration. Here is an example for the :ref:`hello_world` |
| application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: m5stickc_plus |
| :goals: flash |
| |
| The baud rate of 921600bps is set by default. If experiencing issues when flashing, |
| try using different values by using ``--esp-baud-rate <BAUD>`` option during |
| ``west flash`` (e.g. ``west flash --esp-baud-rate 115200``). |
| |
| You can also open the serial monitor using the following command: |
| |
| .. code-block:: shell |
| |
| west espressif monitor |
| |
| After the board has automatically reset and booted, you should see the following |
| message in the monitor: |
| |
| .. code-block:: console |
| |
| ***** Booting Zephyr OS vx.x.x-xxx-gxxxxxxxxxxxx ***** |
| Hello World! m5stickc_plus |
| |
| Debugging |
| --------- |
| |
| M5StickC PLUS debugging is not supported due to pinout limitations. |
