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.

The Atmega 328P chip in the Arduino Uno has three PWM timers (known as Timer 0, Timer 1, and Timer 2) controlling six PWM outputs. Each of the timers has a prescaler that generates the timer clock by ...

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… ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

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 ...

Arduino Gemma from Adafruit is also based on the ATtiny85, and PB0 and PB1 appear to be accessible. This board has a USB connector for programming and a voltage regulator. This board, which I am ...

Provided is a downloadable “clean” sketch (Ardu_Sinewave.ino) for the sine wave generator, which is, in fact, an adapation of the wonderful work by Ken Boak and Trystan Lea.To test this, just attach a ...

The "Design" Image displays the arduino design of Digital Inputs, Outputs and Pulse-Width-Modulation The "Code" Image displays the Code that the Arduino design will execute on. The "Simulated" Image ...
