OBD-II vehicle data for ESP-IDF: read live PIDs, supported-PID maps, and DTCs from an ELM327 adapter over Bluetooth Classic SPP or BLE, or directly off the CAN bus via the on-chip TWAI controller. Shared decode layer, pluggable links, configurable via menuconfig.
Drive WS2812 / NeoPixel (and SK6812, WS2813/15, and clones) LEDs on the ESP32 using the I2S peripheral for rock-solid timing under load. Multiple parallel strips (one per I2S channel), multicore-safe, configurable color order, RGBW, brightness, HSV/gamma utilities, and both a C++ and a C API.
