Hi, this is Cellie from the Netherlands.
My passion is coding—mainly ESP32 using Arduino/PlatformIO—and making complex things simple to use.
Below you can find some of the ESP32 libraries I’ve created to make life easier.
All open-source code I publish is MIT licensed.
If you like what I do, you can support me with a one-time donation.
Any amount is appreciated, but there’s absolutely no obligation.
All donations go toward hardware purchases for future development.
Featured work
-
CelliesProjects/moonPhase-esp32
ESP32 library to calculate the moon phase angle and illuminated fraction for a given time. Version 2.0 introduces API cleanup, stricter compilation, and improved accuracy.
C++ 32 -
CelliesProjects/wm8978-esp32
Arduino IDE library for wm8978 dac on ESP32.
C++ 24 -
CelliesProjects/ESP32_VS1053_Stream
A streaming library for Arduino esp32 with a vs1053 mp3/aac/ogg/flac decoder. Plays http, https and chunked streams. Stream metadata is parsed. Also plays ogg, mp3 and flac from sdcard.
C++ 110 -
CelliesProjects/OpenStreetMap-esp32
This PlatformIO library provides a OpenStreetMap (OSM) map fetching and caching system for ESP32-based devices.
C++ 17 -
CelliesProjects/LGFX-ScreenShot
This library allows you to take screenshots of a 16-bit RGB565 `LGFX_Sprite` or `LGFX_Device` display and save these as 24-bit BMP files on an SD card
C++ 1 -
CelliesProjects/flocking-esp32
