name=SoftPWM version=1.0.0 author=Brett Hagman maintainer=Brett Hagman sentence=A software library to produce a 50 percent duty cycle PWM signal on arbitrary pins.
paragraph=A Wiring Framework (and Arduino) Library, for Atmel AVR8 bit series microcontrollers, to produce PWM signals on any arbitrary pin.
It was originally designed for controlling the brightness of LEDs, but could be adapted to control servos and other low frequency PWM controlled devices as well.
It uses a single hardware timer (Timer 2) on an Atmel AVR 8 bit microcontroller to generate up to 20 PWM channels (your mileage may vary).
