Befaco Midi interface

MIDI Thing v2.2

Firmware for the Befaco Eurorack MIDI module (MIDI Thing).

Requirements

You need Arduino >= 1.6.3.

Additionally you will need the following libraries installed (see the Arduino Guide on how to do this):

• MIDI
• Bounce2
• mcp4728

bug fix

• Fixed Retrigger issues
• Fixed Perc trigger note error.

Uploading the firmware

1. Get an ICSP Programmer We normally use an USBasp programmer like this one https://www.ebay.com/itm/USBASP-USB-ISP-Programmer-for-Atmel-AVR-ATMega328-ATMega32U4-Arduino-/322662323277

2. Download Arduino IDE Go to the official Arduino website https://www.arduino.cc/en/Main/Software and download the latest version of Arduino IDE for your operating system and install it.

3. Download the firmware Go to https://github.com/Befaco/midithing and press "clone or download" to download the repository to your computer. Extract the zip file and copy "firmware" folder to your sketchbook folder.

4. Install the libraries Download the libraries from Library manager (Bounceand MIDI) and install them following the instructions from this link https://www.arduino.cc/en/Guide/Libraries Keep in mind MCP library must be installed from the following link. Do not use library manager one: https://code.google.com/archive/p/neuroelec/downloads

5. Connecting the module Connect the programmer to the ICSP conector in the back of the module. Pay special attention to the pinout when you plug the module. You can check this link for more information about ICSP https://www.arduino.cc/en/Tutorial/ArduinoISP

6. Upgrading Press "Open" and search the file "firmware.ino" located on the "firmware" folder. Select "Tools > Board > Arduino/Genuino Uno". Go to "Sketch" and hit "Upload using programmer".

If everything goes well you should see a "Done uploading" message in a few seconds. If something happens during the upgrade, check your Arduino settings following the instructions of this link https://www.arduino.cc/en/Guide/Troubleshooting
