f28335 Hall signals capture

Hi, I want to capture the Hall signals. When I read Module 7 Example 10, i understand how to measure period or on time of signal. However, i want to see the hall signals in the cap as binary (on time one and off time zero). I studied the eCAP Reference Guide and I see APWM Mode Example. However, I didn't convert APwm signal to ePWM signal. Which bit is output of APwm? Actually, I don't know that APWM mode helps me. If Apwm mode does not help me, what do i do?

    Hi,

    When i looked at Control Suite, i saw bldc sensored example. This example's document mentions Hall_gpio_drv, however i couldn't find it. Although inside of control suite's macro is very complex, i may learn something from it.

    In addition, when i looked at "Example_280xECap_Capture_Pwm.c", i saw that capture registers have rearm mode and one-shot mode. Should i use this mode?

    Thank you,

    Bekir
