3.3.22.6 mcPwm_IntegerScale
C
/* PWM scaling*/
int16_t mcPwm_IntegerScale( const float32_t factor, int16_t input )
Summary
Perform the PWM output scaling.
Description
This function scales an integer input by a floating-point factor. It multiplies the input by the factor and returns the result as an integer. This is useful for adjusting PWM duty cycles in relation to the PWM period counter.
Precondition
None.
Parameters
| Param | Description |
|---|---|
| factor | The floating-point scaling factor used to multiply the input value. |
| input | The integer value to be scaled. |
Returns
The result of scaling the input by the factor, cast to an integer type
Example
float32_t uA;
int16_t pwmPeriodCount;;
int16_t pDutyA;
/** PWM scaling*/
pDutyA = mcPwm_IntegerScale(uA, pwmPeriodCount);
Remarks
Note: The function uses inline assembly for performance
optimization, making it suitable for real-time applications where execution
speed is critical.
