TMS320F28035: eQEP channel A and channel B failure detection

Part Number: TMS320F28035

Hello,

Is there any way to know if there are issues with channel A or channel B on the EQEP module. I am thinking of tying channel A with GPIOx, channel B with GPIOy and check the GPIOs while running the motor.

Is there any other way to verify if the channels are working other than this method?

Thnaks,

Nikit Shah

    Nikit,

    There is actually a dedicated feature for this. The QEPA and QEPB signals generate an internal QCLK that is used with the integrated eQEP watchdog module. This is a 16-bit timer that is reset with every edge of QEPA and QEPB. The eQEP watchdog has a programmable period which is clocked at SYSCLK/64. Please refer to the eQEP Watchdog section of the eQEP User Guide http://www.ti.com/lit/sprufk8 .
