LFO

LFO for Arduino Due (and other Arduino/Teensy/exp32/etc). LFO can be free-running, or synced to a master-clock.

See as well my Youtube video on how to use this class: https://youtu.be/ch03-75Fkuw

Installation

1. Make a new folder called "lfo" in your arduino libraries folder
2. Copy lfo.cpp and lfo.h into the "lfo" folder

How to use

Please refer to the LFO_example.ino file in the examples folder. This file is written for the Arduino Due and can be run on other Arduino boards with some small modifications. I used the Due as it has a built-in DAC. For use on other boards the following changes are to be made to the LFO_example.INO file:

1. Reduce the DACSIZE to 256
2. Remove the analogWriteResolution(12) statement
3. Write to a different port in this statement: analogWrite(DAC0, lfo_class.getWave(t)); ----> for ESP32 use: dacWrite(25, lfo_class.getWave(t));

Updates

• 29.12.2020: initially _mode1_rate was setup as an INT. However, that is problematic when rates smaller than 1 are applied. This is now changed to float. I also added version numbering and a few more get functions needed for the Ableton-control SW.
• 16.07.2022: updated algorithm for Saw and Triangle to be compatible with Arduino UNO (big thanks to othmar52)

Have fun ;-)
