Documentation (in the works):
Documentation on TBD usage can be found here (Google Docs) Tutorial videos in YouTube playlist
Update procedure
Easiest way to update is to use the ready made releases from github. Flash the ctag-tbd.bin and storage.bin from the TBD web ui (within the configuration menu). Alternatively you can connect a USB cable to the TBD and use the serial flasher from esp idf (see how to flash below). In order to use the sample rom, you can upload from the edit sample rom page factory sample data (sample-rom.tbd).
What it is:
- The eierlegende Wollmilchsau (German for swiss army) audio processing module.
- Offering already more than 30 high quality audio generators and effects.
- Open source Eurorack sound module based on the ESP32.
- With an easy to extend audio plugin architecture.
- What you make it.
Why it is:
- A group of audio enthusiasts enjoying coding and hardware making.
- Build a platform to learn, build and practise skills, and engage students.
- To allow anyone to understand technology by offering open access.
- To squeeze and optimize code so that it can work on a small embedded system.
- Because we can.
- To fight boredom and despair of Corona Virus!
Features:
- More than 30 high quality audio generators and effects.
- Easy DSP plugin development.
- NEW!!! Sample ROM playback and wavetable oscillator with user wavetables from sample ROM details here
-
NEW!!! Simulator for cross platform plugin development without hardware module (speeds up plugin development, better code verification).
- Check description here
- With web UI user interface by wireless browser access.
- Through a REST-API.

How to build
You need C/C++ skills. You may want to check the TBD simulator for easy plugin development without TBD hardware. Install espressif esp-idf, instructions are here. Use git to checkout esp-idf release/v4.1 (TBD may build also with newer versions, you can try), do this within the esp-idf folder:
git checkout release/v4.1
git submodule update
sudo ./install.sh
You may need to upgrade CMake to version 3.16 or higher. Then follow these steps to create the firmware image:
git clone https://github.com/ctag-fh-kiel/ctag-tbd.git
cd ctag-tbd
git submodule update --init --recursive
idf.py build
How to flash
Either use the binaries available from the releases from github to flash through the web ui or execute these commands from the command line within the ctag-tbd folder, in which case the module needs to be connected to the PC with a USB cable:
idf.py flash monitor
