MIDI Microcontrollers

Описание: In this video, we cover the topic of MIDI and how we can wire the hardware to use with an STM32 Blue Pill microcontroller using the Arduino framework and PlatformIO.

Special thanks to Jerome Palma of XTRA-SOUR for providing the loops used in the teaser video! Also to Erik Oostveen for pointing out the benefits of using a pulldown resistor with the optocoupler, and to nullpromise for reminding me that TRS-A is now part of the MIDI standard!!!
