Solve Your TTL Video Woes With An RP2350

A hobbyist project called pico-ttl2dvi uses an RP2350 microcontroller to convert old TTL RGB video signals into DVI output, letting owners of vintage TTL video cards use modern monitors. The RP2350's PIOs sample the TTL input into a framebuffer, while PicoDVI handles DVI output. It targets the Waveshare RP2350-PiZero board with its built-in HDMI socket, needs minimal level-shifting hardware (sometimes just resistors), and includes a USB serial terminal plus a Tk GUI script for management. It follows a similar earlier project that converted TTL to VGA.
