Build deterministic composite video on ESP32 with CRT signal core for stable sync, scanlines, and host-checked C11 firmware
ESP32 real-time FDN reverb audio processor - Feedback Delay Network implementation for high-quality audio effects on ESP32-LyraT
Deterministic NTSC/PAL composite video engine for ESP32-D0WD-V3. Signal-first: the scanline is the realtime unit. Output via I2S0 + DAC on GPIO25.
ESP32-C6 Zigbee end device that reads ambient sound levels from a MEMS microphone via I2S and reports normalized RMS amplitude to Zigbee2MQTT.
Multi channel audio broadcast over RS-485 bus (wired interpreteter system) with STM32H533
snapclient on ESP32
A soundboard giving voice to those who don't have it
Multi-Output I2S TX using PARLIO (Parallel IO) Peripheral.
Experimental driver for RPI5 to support multi-channel TDM output.
Real-time audio DSP engine for the 42dB audio platform — STM32-based processing, BLE control, and I2S audio integration.
Open-source ESP32 digital synthesizer democratizing access to professional audio hardware and musical instruments for everyone passionate about music. Built using I2S and Internal DAC.
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
Getting started with various ESP32 development boards. Lots of examples.
An Arduino project that automatically detects if a shower is running and shows a timer for how long you’ve been showering. TinyML using microphone data is used to determine if the shower is running or not.
esp32 version of Ka-Radio (https://github.com/karawin/Ka-Radio) by jp Cocatrix
Network-controlled industrial audio player. ESP32-P4 + Ethernet + REST API + ES8311 codec + LittleFS caching. Upload and play announcements over HTTP. DHCP/static IP, configurable volume, hash-based audio versioning.
ESP32 wireless audio receiver -- decodes IMA ADPCM from ESP-NOW, plays 48kHz 24-bit stereo through a PCM5102A DAC with clock sync, adaptive buffering, and packet loss concealment. Built with ESP-IDF.
