I have been delving (groping blindfold, more accurately) into the Arduino compiler adaptation code to try to determine how it handles the switch-over between its pwm activities, its set-I/O-to-output ...

This repo demonstrates how to work with an Arduino's PWM outputs in a clean programmer-friendly way. It packages all the low-level interaction with timer clocks that underly PWM functionality, ...

Simple Timer for Arduino etc. This is a basic OOP timer implementation for easy low-level handling of schedules or repetitive tasks on embedded hardware. Scroll down for a meaningful example. The code ...
