KXKM - ESP32 Audio & battery module firmware

This repo is a complete Arduino sketchbook with libraries, hardware definitions, etc.

Clone it then point Arduino IDE to it using the Preferences > Sketchbook location.

This repository contains submodules.

Git expects us to explicitly ask it to download the submodule's content. If you're cloning this repository for the first time, you can use a modified clone command to ensure you download everything, including any submodules:

git clone --recursive <url>

If you already cloned the repository you have to run

git submodule update --init --recursive

In order to update the repository submodules content, you can execute the following command regularly:

git submodule update --recursive

ESP32 installation

Execute hardware/espressif/esp32/tools/get.py

STM32 Flashing

You have to export the compiled binary file first (Arduino > Sketch menu).

Using JLink

• Keep the push button pressed to supply power while the MCU is being reprogrammed
• Slide the battery type selector to "Custom" position
• Run the following commands : cd JLinkExe -commanderscript STM32_flash.jlink
