AudioMoth-Project

A port of the original AudioMoth-Project firmware which supports USB MSD protocol interfaces.

This is a fork of the original project.This fork is set up so that it's easier to build, without having to install the Simplicity Studio IDE.

Usage

When run, this implementation will flash both LEDs and handle USB interactions to enable communication with the AudioMoth Time App.

Actions

The AudioMoth firmware has a different behaviour to the standard behaviour of the primary branch firmware.

It is designed to be permanently set the device in the USB position, and enclosed inside a sealed casing.

• Pull pin SWDIO high to force audio recording
• Pull pin SWDIO low, to stop audio recording
• To flash the AudioMoth
  • Pull pin RST low, to force the AudioMoth to reset
  • Pull pin SWCLK high, to stop the MCU clock
  • Pull pin RST high, to permit the MCU to resume

Requirements

• cmake - use Brew on OSX, or your favourite package manager for Linux.
  • cmake must be version 3.15 or greater
  • sudo apt-get install cmake will typically install an old version of the product
  • sudo apt-get purge cmake && sudo snap install cmake --classic will replace an existing cmake instance with a more recent version
• git - use Brew on OSX, or your favourite package manager for Linux.
• make - should be available by default, otherwise as above.
• arm-none-eabi-gcc - The GNU ARM Embedded Toolchain

Building

1. git clone --recurse-submodules https://github.com/victorromeo/AudioMoth-MSD.git to download this repository.
2. mkdir build-release to create the build directory.
3. cd build-release to switch to the build directory.
4. cmake -DCMAKE_BUILD_TYPE=Release .. to configure the build. Use snap run cmake -DCMAKE_BUILD_TYPE=Release .. if using a snap installed version.
5. make to execute the build.

You should get a AudioMoth-Project.bin with your custom firmware, which you can then flash to the device.

Debug

Requirement for environment variable ARM_NONE_EABI pointing to current ARM toolchain installation, i.e. in .bashrc
