I was hoping to find a 'blink the LED' example for the ESP32. Then I'd like to see 'Blink a LED at 1Hz and another LED at 1.234Hz' (or any pair of frequencies where one does not divide the other).
Blinking leds at precise frequencies is not the intended use of LispBM. It's not a language for real time guarantees. The idea is to add scriptability and versatility to embedded applications written in c/c++ (or anything else which can link in a c library). If you want a precise led blinker you would write low level real time led blinker in c. You could then set up scripting of this led blinker using LispBM. Maybe you want to receive the frequency to blink the led at over Can?
