Let's Build a VGA GPU Card On RP2350 - Part 1 The Design

VGA signal is one thing. VGA card is another!

Of course! And this card will be a real "gpu" like card. With VGA( and DVI ) signals driven from PIO. And text and graphic modes frame generation on those 2 cortex-m33. I have a proof of concept on two raspberry pico with rp2040 with even some experiments with simple 3d acceleration.

Awesome!

Thanks!

I think this is great, you skiped some of the detial on VGA technology and how it syncs, and generates frames. I think going into that detail would help others gravitate towards your simple yet more detail then average videos. People want to know how things work but may not want the technical explinations. Great job!

Thanks! This will be covered in a dedicated episode. I plan to make it together with graphs from the oscilloscope. But it must wait for RP2350 arrival and board soldering and most probably fixing :) this video is just a short overview of the first step!
