Lightweight framebuffer drawing utility for AI annotation overlays. Supports text, rectangles, lines, point markers, and detection boxes in RGB565/RGB888 with built-in bitmap fonts.
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.
Timestamp service for ESP32 that works without a dedicated RTC module. Starts from build time on every boot, then corrects via SNTP sync or manual set — whichever suits the application. All corrections are explicit and observable via jump callbacks, safe for logging systems.
System identity / status (chip, app, partitions, reset reason, uptime, heap) and restart control (reboot, reboot into the ROM bootloader), plus a framed stream service and a browser console (WebUSB / Web Serial)
