AVRPWM0Setup Function to Setup OC0 pin for required PWM mode waveform_mode: integer, from 0 to 2 output_mode: integer, from 0 to 1 (or 2) depending on the waveform_mode Every Micro controller has PWM pins which can generate varying voltages from 0V-5V.This function helps to use OC0 pin to produce required output waveform by setting the waveform mode and otput mode. waveform_mode can take values- 0 -> for Phase correct PWM Mode 1 -> for Fast PWM Mode 2 -> for CTC Mode output_mode can take values- For Phase correct PWM Mode: 0 for Clear OC0 on compare match when up-counting. Set OC0 on compare match when down-counting. 1 for Set OC0 on compare match when up-counting. Clear OC0 on compare match when down-counting. For Fast PWM Mode: 0 for non-inverted output i.e Clear OC0 on compare match, set OC0 at BOTTOM. 1 for inverted output i.e Set OC0 on compare match, clear OC0 at BOTTOM. For CTC Mode: 0 to Clear OC0 on compare match 1 to Set OC0 on compare match 2 to toggle OC0 on compare match This is curretly dummy function. It provides no functionality but is required for providing support for generating C code for AVR. AVRPWM0SetDuty Ashish Kamble
