CHAPTER 6

The N variable represents the 

prescaler

factor (1, 8, 64, 256, or 1024). Some

modules also support 32 and 128 

prescaler

value, but for this you will need to

check the datasheet for the desired MCU)

PWM1_Init must be called before using other functions from PWM Library.

You need a CMO on the given MCU (that supports PWM). 

Before calling this routine you must set the output pin for the PWM (according
to the datasheet):

DDRD.7 = 1; // set PORTD pin 7 as output for the PWM1 

This code oxample is for ATmega16 (second PWM module), for different MCU
please consult datasheet for the correct pinout of the PWM module or modules.

Initialize PWM module:

PWM1_Init(_PWM1_FAST_MODE, _PWM1_PRESCALER_8, _PWM1_NON_INVERTED,
