`gledopto`

Rust no-std embedded board support crate for Gledopto ESP32 Digital LED controllers.

Uses Blinksy: an LED control library for 1D, 2D, and 3D LED setups, inspired by FastLED and WLED.

Supported Boards

Gledopto GL-C-016WL-D, gl_c_016wl_d
Gledopto GL-C-017WL-D, gl_c_017wl_d

Select the board by using its respective feature.

Features

LED control using blinksy
Built-in "Function" button
Alternative "IO33" button
Built-in microphone
