Pico2DVI the Graphics Card You Can Build Yourself!
Recently, I began exploring circuit design, and I liked the idea of creating my own custom graphics card because it sounded like a fun project. After some back and forth of choosing requirements for the GPU, I settled on using a Raspberry Pi Pico as the main processor. It already had a graphics library made for it, which would make adding HDMI support simple. I saw PicoDVI by Luke Wren, but I wanted to add more RAM and some extra capabilities. I added 32MB of VRAM (Video Random Access Memory), which is about 250 times less capacity and 36 million times slower than the memory on a modern GPU. (As you can probably tell, I was not going for speed.) The Pico also has Wi-Fi and extra general-purpose pins. That means the card can take in user inputs like a keyboard and output data in ways other than just a display. It can also fetch data (e.g stock market information) from the Internet. I prioritized versatility over speed.
