But, the Arduino developers (Wiring maybe, this is old stuff) could easily have solved this in a much more efficient way by simply using the inverted Fast PWM mode instead of non-inverted.

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, ... digitalWrite(LED_BUILTIN, HIGH); // turn the LED on ... and am currently trying to generate two phase ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using th… ...

Arduino can deliver high-speed PWM For a long time I have admired the pulse-with modulators designed into Atmel (now Microchip) AVR microcontrollers . The company was early into adding phase-locked ...
