AVRPWM2SetDuty Function to Set Duty cycle of PWM Output generated by Timer2 at OC2 pin. duty : It holds an integer value from 0 to 100 which sets the percentage of time for which signal is active. Each Micro controller has PWM output pins which can generate varying voltage from 0V-5V.In this function by varying the duty cycle, varying voltage can be produced. This is curretly dummy function. It provides no functionality but is required for providing support for generating C code for AVR. Example AVRPWM2SetDuty(50); //Produces 2.5V at OC2 pin AVRPWM2SetDuty(0); //Produces 0V at OC2 pin AVRPWM2Setup Ashish Kamble
