Some weblog posts tend to take me further away from the usual topics. No worries… it’s just that I want to explore some “outer edges” to better understand complexity & speed trade-offs between µCs and FPGAs.
So… let’s generate a video signal with a µC!
This is the HyTiny-based STM32F103 RF Node Watcher I used before, re-purposed here to generate a composite video signal.
Black-and-white composite video is very easy to generate – it needs just two output pins and two resistors.
