Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Microcontroller VGA Interface Projects
The RP2040 (as used by the Raspberry Pi Pico) can generate some impressive video thanks to its PIO. E.g. Luke Wren's work giving DVI output https://github.com/Wren6991/picodvi and the scanvideo library: https://github.com/raspberrypi/pico-playground
I did a write up going over how to generate VGA video from scratch to produce some SNES like graphics:

Got I2S DAC working with Pico!
I used the USB sound card example: https://github.com/raspberrypi/pico-playground/blob/master/apps/usb_sound_card
-
Cool, the Raspberry Pi folks already figured out turning the Pico into a USB sound card!
You'll need to edit this file after you download it first. Add the lines PICO_AUDIO_I2S_DATA_PIN=28 and PICO_AUDIO_I2S_CLOCK_PIN_BASE=26 in the compile definitions. After that, you can compile it as normal.

FuryGpu – Custom PCIe FPGA GPU
The RP2040 is a great MCU for playing with graphics as it can bit bang VGA and DVI/HDMI. There's some info on the DVI here: https://github.com/Wren6991/PicoDVI
I wrote a couple of articles on how to do bit banged VGA on the RP2040 from scratch: https://gregchadwick.co.uk/blog/playing-with-the-pico-pt5/ and https://gregchadwick.co.uk/blog/playing-with-the-pico-pt6/ plus an intro to PIO https://gregchadwick.co.uk/blog/playing-with-the-pico-pt4/

Video Game Module for Flipper Zero
A few years back someone was bit banging DVI and 720p 30fps video straight off the RP2040 GPIO pins with just inline resistors between not and the HDMI cable.

VGA driver using PIO and DMA on the RP2040
I have the Adafruit DVI board and have been hacking on it some. It's more fun than should be allowed.
There's a project to get this running using Rust[1]. Currently it outputs the blue channel with sync, but has trouble with the other two channels. I don't have a hardware lab with scope, logic analyzer, etc., so it's not easy for me to debug.
In the meantime, I've been doing some experiments in the C codebase as well[2], mostly in the direction of proportionally spaced bitmap text, using the fonts in the X11 distribution.

Recommend MCU with dual USB - one host and one device IF?
There is even bit-banged DVI library for pico.

Show HN: PicoVGA Library – VGA/TV Display on Raspberry Pi Pico
Apparently, there is a digital video output project for the RP2040 already out there [0]! As for why digital video is more rare, it is because the common digital video formats are higher bandwidth and require higher signal integrity.

Least resourceful 18 year old air defense ukrainian soldier with basic coding abilities
I've seen people implement DVI with PIO, and I'm sure basic missile commands wouldn't be as bandwidth-intensive as that.

Help understanding current-mode and TMDS logic in DIV/HDMI.
For example this guy (https://github.com/Wren6991/PicoDVI) essentially 'bit bangs' CML. Sure its not a completely compliant implementation, but it's pretty close... In his case using a push pull with 3.3V/0V. I don't know how he's getting a 0.8V swing.
