(Sponsor) This video show a little game console that I designed around the CH32V003 risc-V microcontroller. The interesting part is that it drives the 240 LED screen directly from 16 pins. The way tri-state buffers work allows to utilize the third state to drive many LEDs with only few pins. On top of that the video explains some of the design considerations of this little project and how get is cheaply manufactured.
