What

I have an AudioMoth board, and plan to improve its software:

• https://www.openacousticdevices.info/
• https://github.com/OpenAcousticDevices/AudioMoth-Project source code

Hardware

See https://circuithub.com/projects/OpenAcoustics/AudioMoth

• microphone is SPM0408LE5H, datasheet
• processor is EFM32WG380F256, link

Software

My fork on github: https://github.com/bertrik/AudioMoth-Project

Running the tools

Running the tools (configuration tool, flash tool, etc) requires the --no-sandbox option (at least on my system), for example

 ./AudioMothConfigurationAppSetup1.2.5.AppImage --no-sandbox

IDE for development

A brave attempt for all the steps to get the firmware compiled was written here: https://github.com/OpenAcousticDevices/AudioMoth-Project/wiki/AudioMoth

Compiling

platformio

It compiles and produces a firmware.bin file, but it's not recognized by the flashing tool as a valid file.

Use this platformio.ini file:

 [platformio]
 src_dir = src,fatfs_src
 include_dir = inc,fatfs_inc
 [env:default]
 framework = zephyr
 platform = siliconlabsefm32
 board = efm32wg_stk3800

Install platformio:

 sudo apt install python3-pip
 sudo pip3 install platformio
 sudo pip3 install -U PyYAML

Compile it:

 pio run
