  1. Teensy 4.0 Capacitive Sensing alternative

    I just updated my FastTouch library (https://github.com/adrianfreed/FastTouch) for Teensy 4.0 support. It is a basic library for quickly sensing when
    a pin is touched. It may work for your ...

  4. Help with List of Teensy Eurorack modules

    I am exploring OSC (Open Sound Control) integration with Eurorack Modules. My starting point is developing a list of modules that build on Teensy 3.x.

    Could you please help me by adding modules...

    It has the same DSP instruction support as M4. Main changes are wider bus (64-bit), faster memory, higher clock rate and big caches.
    It is more energy efficient which allows the higher clock rate.
