Implementation

Measuring PWM frequency and duty cycle

The measurement of the PWM frequency and duty cycle is done by calling the

function measure_PWM() containing the following steps:

› Update the measured PWM data by calling the iLLD function

IfxGtm_Tim_In_update()

› Get the PWM period in seconds with the iLLD function

IfxGtm_Tim_In_getPeriodSecond()

› Calculate the PWM frequency with the formula: frequency(Hz) = 1 / period(s)

› Get the PWM duty cycle by calling the iLLD function

IfxGtm_Tim_In_getDutyPercent()

All the iLLD functions above are provided by the iLLD header IfxGtm_Tim_In.h
