esp32-wm8978-arduino-sinewave | Example Arduino sketch showing how to make sound

esp32-wm8978-arduino-sinewave is a C++ library typically used in Internet of Things (IoT) applications. esp32-wm8978-arduino-sinewave has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This is an example Arduino sketch for the TTGO T-Audio board (an ESP32 based board with a WM8978 audio codec, SD-card, RGB Leds, MPU9250, etc.) Technical documentation here : This sketch only generates a sinewave, but it took me quite a long time to make it work. That’s why I share it here, so that you can clone the repo and make so noise straight on :) It can be useful if you want to start making some sound synthesis in C++, for example. The code generated by the Faust sawtooth example helped me a lot. The WM8978 driver files come from the Faust project.
