This library is designed to work with AVR Micro-controllers: ATmega48A/PA/88A/PA/168A/PA/328/P, So you can use it directly with Arduino UNO, Duemilanove and other boards with those micro-controllers. It enables you to generate multiple PWMs with the same frequency with different duty cycles on any I/O pin. It has different technique from "Servo.h" in Arduino libraries. Number of valid generated PWMs depends on frequency chosen, duty cycles chosen for each PWM and -of course- the number of available I/O pins.
1- You are limited to create only one instance(object) of the PWM class in your code.
PWM object_name(number_of_PWMs, operating_frequency_of_microcontroller, PWM_frequency, prescalar);2- You MUST do this step in your code.
object_name.CreatePWM(&object_name);3- Create a PWM.
object_name.attachPWM(index_of_PWM, address_of_desired_PORT, address_of_desired_DDR, pin_number, max_duty_cycle, min_duty_cycle);=> index_of_PWM: 0...n ;where n = number_of_PWMs - 1
=> address_of_desired_PORT: e.g. &PORTB
=> address_of_desired_DDR: e.g. &DDRB
4- Start generation of PWMs.
object_name.startPWM();5- You can change duty cycle of any PWM at run time.
object_name.SetPWM_DutyCycle(new_duty_cycle, index_of_PWM);Library will support more AVR micro-controllers.
