The topic of video output with microcontrollers goes back to the beginnings of these small all-round chips. Today’s microcontrollers have considerably more computing power than, for example, the almost 42-year-old Sinclair ZX81 home computer, but even current microcontrollers are a long way from the memory size of modern graphics cards measured in gigabytes. Nevertheless, developers still manage to output amazing moving images with an ATmega, an ESP32 or an RP2040. In the first part of this series, we will cover the output of composite video. In the next issue, we will continue with VGA and even DVI. In any case, a few tricks and exact timing are necessary. Therefore, this is not only about theory, but also about practical examples as a starting point for your own experiments.
