PicoDVI fork for NULA Max RP2350


This is a Soldered Electronics fork of the Adafruit fork of original PicoDVI library, updated and adapted for the Soldered NULA Max RP2350 board. The goal of this fork is to make DVI output on the RP2350 easier to use out-of-the-box, with minimal setup and cleaner integration into Soldered’s development workflow.

What’s changed

  • Updated pin mappings and sensible defaults for the NULA Max RP2350
  • Simplified configuration for common video modes
  • Minor fixes and adjustments for Max RP2350 compatibility
  • Streamlined example sketches for quick testing on Soldered hardware

Why this fork exists

The original PicoDVI library was designed for RP2040-based boards. While it mostly works on the RP2350, several adjustments were required to ensure stable DVI output and seamless operation with Soldered’s board layout, bootloader, and recommended workflow.

Compatibility

  • Fully supported: Soldered NULA Max RP2350
  • compatible: Other RP2350 boards (may require manual pin remapping)
