"wouldn't it be absurd and wonderful to connect your microcontroller straight to an HD TV with no other electronics in between? "

Not sure about that, but the article is well written and demonstrates what (and perhaps more importantly, how) can be done with the state machines + DMA on a RP2040. Thanks for sharing.

Reading this makes me wonder about just one thing: why does TDMS encoding need to be done live? screen changes are rare. keep data in RAM in TDMS format (the 25% growth in size isn't much) and just DMA it out
