# HyperLink_SW

Firmware for the HyperLink board.

## Build and run

This project is built using the [ESP IDF](https://docs.espressif.com/projects/esp-idf/en/release-v5.1/esp32/index.html) toolchain.
In order to ease the build process, a custom `Dockerfile` is provided.
Any ESP IDF toolchain command can be run by replacing `idf.py` by `./idf.sh`, e.g., `./idf.sh build`,
after having built the docker image.

As the docker container has to be able to access the serial device for flashing,
some configuration may have to take place.
Make sure the `USB_GUID` and `USB_DEV` in `idf.py` have the correct values.

1. Build the docker image
    ```bash
    $ sudo docker build . --tag hyperlink
    ```

2. Compile the project
    ```bash
    $ ./idf.sh build
    ```

3. Flash the executable
    ```bash
    $ ./idf.sh flash
    ```
