NuEVI-audio Add NuEVI version with audio output (from Johan) 2019-03-04 10:21:21 +01:00

TestMPR121 Test tool for MPR121 modules. 2019-12-23 00:41:15 +01:00
uploadable hex files * Added three new settings in EXTRAS MENU – CV TUNE, CV SCALE and CV EC LFO. The first two allow for software tuning of the CV output for 1V/Oct when using NuEVI CV, NuEVI Plus or NuEVI/NuRAD with external CV box or module. Also makes more simple versions of the CV boards possible (no potentiometers for adjustment). The CV EC LFO setting controls a new CV LFO vibrato function for the extra controller (lip sensor). It can be set to OFF (no extra controller LFO vibrato) or values 1 through 8, which represent vibrato freq from 4.5Hz to 8Hz. Default value is 3 (5.5Hz). 2021-02-20 15:35:01 +01:00

NuEVI

A project by wind controller enthusiasts wanting to save the endangered Electronic Valve Instrument.

Building NuEVI

NuEVI is easiest to build using the Arduino IDE. You will also need to download and install Teensyduino to build for and upload to the Teensy.

Libraries

A few libraries need to be added that are not part of the default Arduino install. These can be added directly via the Library Manager in the Arduino IDE:

  • Adafruit MPR121
  • Adafruit GFX
  • Adafruit SSD1306 (version 1.2.9 or above)
  • NuEVI also includes on the Filters library by Jonathan Driscoll, but that is no longer an external dependency.

Compile options

Open NuEVI.ino in the Arduino IDE. Under "Tools -> Board", select "Teensy 3.2 / 3.1". Then set "Tools -> USB Type" to "MIDI".

Building and uploading

Connect the NuEVI via USB to your computer, open the Teensy application and make sure the "Auto" option is selected (the green round icon). In Arduino IDE, select "Sketch -> Verify/Compile" and once that is complete press the reset button on the Teensy chip (you have to remove the top cover on the NuEVI to access this). Upon resetting, it should upload the new firmware onto the NuEVI.

After uploading new firmware, you may need to reset the config memory of the NuEVI. To do this, press and hold the MENU and ENTER buttons while turning on the NuEVI. Note that this resets all sensor calibrations too. For new versions this should not be neccessary, as value and version checks are in place.
