What

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

Ideas:

  • general clean-up
    • fix white space, remove many of the empty lines (earlier CR/LF mistake?)
    • fix sprintf statements
    • fix complicated and non-portable casts (sensitive to endianness)
  • update tool-chain to newer version
    • update gcc
    • attempt to make it possible to compile with platformio
    • document it and upstream it when it works
  • extend functions
    • add trigger functionality, maybe a specific bat trigger (high pass filter)?
    • crest (instantaneous vs average) trigger?
    • save files in sub-directories (per day) instead of a flat filesystem?

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
