pi-Stomp Software and Firmware

We start with a 64-bit Raspberry Pi lite operating system. We then add MOD, which is an open source audio host & UI created by the awesome folk at moddevices.com

The pi-Stomp hardware requires drivers to interface with the LCD, potentiometers, encoders, footswitches, MIDI, etc.

A pi-Stomp software service, mod-ala-pi-stomp, uses the drivers to monitor all input devices, to drive the LCD and to, among other things, send commands to mod-host for reading/writing pedalboard configuration information.

This repository includes:

• the pi-Stomp hardware drivers ('pistomp' module)
• the mod-ala-pi-stomp service ('modalapistomp.py' & 'modalapi' module)
• setup scripts for downloading/installing the above along with:
  • python dependencies
  • MOD software
  • sound card drivers
  • system tweaks
  • hundreds of LV2 plugins
  • sample pedalboards

Installing

For full installation instructions including etching the initial operating system, see this guide

After first boot, establish an ssh session to the RPi (the password is the one set during OS install):

    ssh pistomp@pistomp.local

Once connected, download the pi-Stomp software:

    sudo rpi-update

    sudo apt update --fix-missing && sudo apt install -y git

    git clone https://github.com/TreeFallSound/pi-stomp.git

    cd pi-stomp

Now run the setup utility to install the software and audio plugins. It could take over a half hour. There are a few setup options based on your system hardware. Typical systems should run:

    nohup ./setup.sh > setup.log | tail -f setup.log

The IQAudio Codec Zero is the default audio card, so the above command is equivalent to adding -a iqaudio-codec (eg: ./setup.sh -a iqaudio-codec). For an audioInjector card, add: -a audioinjector-wm8731-audio For HiFiBerry add: -a hifiberry-dacplusadc For the original v1.x hardware, add -v 1.0

If all went well, the system will reboot, then finally display the default pedalboard
