   This started because I built a full-size Robby the Robot suit and discovered I couldn&#x27;t actually see out of it (<a href="https:&#x2F;&#x2F;youtu.be&#x2F;gAHd46ErNA8?si=-iOwbobp4trPXdGB" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;gAHd46ErNA8?si=-iOwbobp4trPXdGB)

   I bought a $35 backup camera&#x2F;display to solve that problem, then discovered that the display contained an AMT630A video processor with a surprisingly capable OSD system. That sent me down a rabbit hole of I2C probing, firmware dumping, register tracing, custom graphics, bitmap formats, hidden factory menus, and eventually figuring out how to use an ESP32 to generate a programmable HUD over the live composite video.

   I ended up turning what I learned into an Arduino library, which I&#x27;ve released on GitHub. It supports built-in and custom fonts, multiple OSD windows, 16-color bitmaps, palettes, transparency, and animation. It can also be used with composite video sources other than the camera.

   The library and code are here: <a href="https:&#x2F;&#x2F;github.com&#x2F;mogrinz&#x2F;AMT630A" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;mogrinz&#x2F;AMT630A You can also install directly from the Arduino IDE Library Manager (search for AMT630A)

      @dang Could HN remove source identifiers from links by default?
