How to use Ts in eCAP Module for finding speed using the hall sensors?

I want to run my motor using hall sensors in an open loop mechanism. I tried directly giving the pwm signals using ePWM blocks. Now, I need to use the real time hall signals and capture them using eCAP and process to get speed and input to PWM Signals.

I am unable to configure eCAP to get the speed and generate signals. Is there any tutorial that uses eCAP module?

Thanks in advance.

Hi Varun,

There's an example model 'c28069pmsmfoc_ert' in Embedded Coder Support package for TI C2000 processors on field oriented control of PMSM using Piccolo F28069 and DRV8312EVM that uses Hall sensor based speed control.
