Infrared remote library for ESP8266/ESP32: send and receive infrared signals with multiple protocols. Based on: https://github.com/shirriff/Arduino-IRremote/
Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, OGG/Opus, MP3, and AAC files on I2S DACs or with a software emulated delta-sigma DAC on the ESP8266 and ESP32 and Pico
GUIslice drag & drop embedded GUI in C for touchscreen TFT on Arduino, Raspberry Pi, ARM, ESP8266 / ESP32 / M5stack using Adafruit-GFX / TFT_eSPI / UTFT / SDL
Can bus monitoring tool based on arduino and can bus shield. Implements CAN ASCII/SLCAN protocol compatible with Lawicel CAN232/CANUSB. Can be used for monitoring low speed CAN (interior can bus of most cars, less than 500kbps). For higher speeds serial port can become a bottleneck in case data density is high.
