RP2350 Converts TTL Video to DVI

A new project offers a solution for users with older TTL video cards and no compatible monitors.

The converter uses an RP2350 microcontroller to sample TTL input signals into a framebuffer and then generate a DVI output using PicoDVI.

The project requires minimal level-shifting hardware, such as resistors, and is designed for the Waveshare RP2350-PiZero board, which includes an HDMI socket.

A USB serial terminal is available for managing the device, complete with a TK GUI script for user interaction.

This project addresses a niche but important need for interfacing legacy TTL video hardware with modern display standards.
