Implementation

Setting the duty cycle

The setting of the duty cycle is done by calling the function setDutyCycle(), which contains the

following steps:

›

Set the dutyCycle parameters of the instance of the configuration structure to set theduty

cycle for the PWM signal to the desired value

›

Call the function IfxGtm_Atom_Pwm_init() to re-initialize and re-activates the ATOM with

the new configuration.

The functions IfxGtm_Atom_Pwm_init() is provided by the iLLD header

IfxGtm_Atom_Pwm.h.

Fading the LED

The fading of the LED is done in the function fadeLED() by repetitively adding or removing a

step value to the duty cycle of the PWM.
