Streaming region-of-interest JPEG decoder for ESP32 based on tjpgd. Stream JPEG data in from any source, stream decoded pixel rows out to your callback — without loading the full image into RAM, without a seekable source, without a full-frame output buffer. Stream in from a file, a flash blob, an HTTP response body, a UART byte stream, a FreeRTOS queue, a TCP socket, or a DMA ring buffer. If you can hand bytes to a callback, you can decode a JPEG.
ESP32 RF Module Library for 315MHz and 433MHz signal transmission and reception. Designed for xiaozhi-esp32 project with MCP tools integration for AI voice control.
Runtime hot reload for ESP chips - load and reload ELF modules without reflashing. Enables rapid iteration during development by updating code over HTTP while the device keeps running.
