An Arduino Library for working with the AMT630A chip
An Arduino/ESP32 C++ library that unlocks the hidden on-screen display (OSD) engine in AMT630A-based composite-video LCD monitor boards — the cheap chips found in $35 backup-camera displays. It exposes five hardware OSD windows for text, custom glyphs, 4bpp bitmaps, palette animation, blending, and scaling, plus a Python image converter and factory-menu automation.
Why now: It accompanies a Hacker News discussion about reverse-engineering a $35 backup camera display, and there's a project video on YouTube demonstrating the resulting HUD.
Who it is for: Makers and hardware hackers who want to add overlays or HUDs to cheap composite-video LCD modules using Arduino or ESP32.
