Raspberry Pi Pico DVI: Demo del Motore Grafico in Tempo Reale

Gli ingegneri di Elektor dimostrano come il Raspberry Pi Pico (RP2040) sia in grado di generare al volo un video con risoluzione 640×480. Guarda come esplorano sprite, tile map ed effetti grafici classici.

Raspberry Pi Pico DVI output? Take a look back at the impressive video generation capabilities of the original Raspberry Pi Pico — the tiny RP2040-based board that continues to surprise with what it can do.

Raspberry Pi Pico DVI with Minimal Extra Components

In this segment from Pixel Art Magic with Microcontrollers, we see how the Pico generates 640×480 graphics in real time using nothing more than a few resistors and a DVI header. The output is entirely computed on the fly, with the microcontroller building each frame pixel by pixel, line by line, before sending it to the display.

Engineer Mathias Klaussen explains that the Pico doesn’t have enough RAM to store a full image, so the ingenious code reconstructs everything in real time, shifting data just ahead of the video signal, “chasing the beam.”

The demo covers several examples, including classic tile maps and sprite-based animation reminiscent of early consoles such as the NES, SNES, and C64. The discussion also touches on Mode 7 rendering for pseudo-3D racing effects, and even the possibility of running Doom on the RP2040 with a bit of overclocking.
