    The PMOD interface is just wiring to the dac chip. I did not make any effort to support the dac as an audio interface for the Teensy Audio Library. But now that I think about it, that would be fun. I still have the...

    This is part of a larger project using Teensy 4 and LC to control analog synthesizer circuits. The PAIA drum tone board provides the basic percussion sounds, and I am using the Teensy Audio Library to generate white...

    LC documentation says, TPM0 - Controls PWM pins 6, 9, 10, 20, 22, 23. Used by AltSoftSerial library and PulsePosition library. TPM1 - Controls PWM pins 16, 17. TPM2 - Controls PWM pins 3, 4. I am assuming one...

    This uses the Audio Library on the DAC port. It uses a number of PWM pins and digital pins to control a PAIA drum tone board with vactrols added. const int numLeds = 6; int pwmLeds = {16, 6, 3, 10, 17, 20}; int...

    Hello All, tldr: Are some PWM pins timers mutually exclusive to the Teensy Audio Library on the LC? I can share some snippets when I get on my main laptop this afternoon. I wanted a MIDI-controller for 5-6 old...
