ESP32 Oscilloscope Clock

Recently my employer was nice enough to send me a new Rigol MS05104 4 channel scope for my home lab.  As it has been forever since I've needed to work with a scope, I used one of Bill's tutorials ( https://dronebotworkshop.com/esp32-dac/ ) to get back into scope-shape by using an ESP32's twin DACs to make some waveforms.  When I got to the oscilloscope art section and making circular waveforms using XY mode, my mind went back to an article I once read about using the XY mode and a microcontroller to make an analog oscilloscope clock.  So I went down that rabbit hole and found some information online, but it is quite old and the code didn't work with the modern version of the libraries used.  I wasn't able to work through all of the errors and shelved it, but maybe this would make an interesting tutorial for Bill to modernize.
