Implementation

Initialization of PWM Buzzer

The initialization of the PWM Buzzer is done once in the setup phase by calling the function

initPWMBuzzer(), which contains the following steps:

›

Initialize the time constants by calling the service function initTime() from iLLD header file

Bsp.h

›

Enable the GTM by calling the function IfxGtm_enable()

›

Enable the FXU clocks by calling the function IfxGtm_Cmu_enableClocks()

›

Initialize the timer configuration with default values by calling the function

IfxGtm_Tom_Timer_initConfig()

›

Set the timer configuration variable timerCfg with the user defined values

›

Initialize the timer through the iLLD function IfxGtm_Tom_Timer_init()

›

Enable the GTM TOM channel 4 by calling the iLLD function

IfxGtm_Tom_Tgc_enableChannelsUpdate()

All the functions used for the configuration of the PWM Buzzer are provided by the iLLD header

IfxGtm_Tom_Pwm.h.
