'Out of tree' project that modifies a value when a rotary encoder is rotated.

Uses the Seeed XIAO ESP32 S3 using the Zephyr RTOS. It should be straightforward to adapt to other ESP32S3 boards.

This assumes you've already installed & configured Zephyr.

Currently need to be

    git checkout v3.6-branch

As normal, source the environment:

    source ../zephyrproject/.venv/bin/activate
    source ../zephyrproject/zephyr/zephyr-env.sh
    source ../zephyrproject/zephyr/scripts/west_commands/completion/west-completion.bash

Espressif HAL requires binary blobs for peripherals to work. Run the command below to retrieve those files.

    west blobs fetch hal_espressif

Build application & bootloader

    west build -p always -b xiao_esp32s3/esp32s3/procpu

    west flash

west build -t guiconfig --board xiao_esp32s3/esp32s3/procpu
