INPUT CAPTURE

[kaarthichandras]

Hi,

Iam using S12zvml31 controller for sensorless commutation for bldc motor control. I configured TIM0 channel 0 and channel 3 as output compare mode for sensorless algorithm. Now I want to measure external pwm pulse through input capture, in which pin I have to connect that pwm signal. And how to use that TIM0?

Thanks and regards,

Kaarthi.

Hi,

You can refer to S12ZVL-TIM-FrequencyMeasurement-V1_0-CW106-TIC-EXAMPLE 

It can be modified for pulse width measurements.
