eQEP usage using HALCoGen Library

Application Description:

Motor Control of an Induction motor using a Scalar V/F scheme. The requirement to measure speed from 30 rpm to 2800 rpm with the 200/256 cpr ecoder/disc installed.

Problem and Issues

1. For low speeds, the 16-bit QCPRD register I am reading overflows and thus I am reading erroneous values.
2. I feel the descriptions for the functions defined in the eqep.h/eqep.c are insufficient. Clarification regarding their purpose would be appreciated.
3. The example code in example_eqepEdgeCapture.c does not use the "standard" functions generated by HALCoGen (Code exerpt below). Is there a reason for that?
   

   /* Status flag is set to indicate that a new value is latched in the QCPRD register. */
   if((eqepREG1->QEPSTS & 0x80U) !=0U)
   {
   	/* Elapsed time between unit position events */
   	deltaT = eqepREG1->QCPRD;
   
   	/* Calculate Velocity from deltaT and the value of the unit position. */
   	/* The value of Unit Position is a sample value and should be changed by the User as per the actual value in the UNIT_POSITION_X macro above. */
   	velocity = (float)(UNIT_POSITION_X/deltaT);
   
   	/* Clear the Status flag. */
   	eqepREG1->QEPSTS |= 0x80U;
   }
   

4. What would be the suggested/recommended settings for the EQEP module in HALCoGen for such an application.

Thanks
