ESP32 and PWM

I'm continuing reinventing wheels with my ESP32. In ESP32 and Mozzi I was using the built-in DAC for audio output. In this post I'm taking a detailed look at how to use PWM for audio output instead. Part 1 - All the theory and research around PWM and the ESP32. Part 2 - Generating different waveforms on … Continue reading ESP32 and PWM →

ESP32 and Mozzi

I've been meaning to do something with the ESP32 for some time. I have some general ESP32-C3 devices, and a range of XIAO ESP32 (S2 and C3) devices too, but what I was particularly interested in was the original ESP32 as it includes two 8-bit DACs. This is my first set of experiments using a … Continue reading ESP32 and Mozzi →

Arduino Audio and MIDI Frameworks

I've been collecting bookmarks for interesting Arduino audio projects for a while now, and having now played with the XIAO SAMD21 I started looking back over my list for other things to try. One thing that occurred to me is that there are a now a number of more powerful audio frameworks available for a … Continue reading Arduino Audio and MIDI Frameworks →
