TMS320F28378D: interface to absolute position encoders

Roberto Sánchez
Prodigy 30 points
Part Number: TMS320F28378D
Other Parts Discussed in Thread: CONTROLSUITE

Hi:

We are working in a motor control application with TMS320F28378D microcontroller. We should be able to manage the following interfaces and encoder types:  quadarture, hiperface, EnDat01, BiSS-C and preferably also SSI. We have analysed the support provided by you and we have some questions we would like to clarify:

  • Do you recommend the use of your libraries in MotorControlSDK or is it better to use ControlSuite with CLB and modify it according to our necessities?
  • Do you think is it possible with existing CLBs to provide support to all that type of Encoder?
  • We already have the HW and many of our I/O are allready used. How could we configure CLBs in that scenario?
  • Is available the Hiperface (not Hiperface DSL) example?

 Thanks for your support.

    Our latest software is in the MotorControl SDK. For absolute encoder interfaces, only T-format is in the SDK and fully documented with source code.

    quadrature decode is supported by our eQEP peripheral

    EnDat01, BiSS-C

    EnDat2.1 and BiSS-C are not supported in the MotorControl SDK at this time. Unfortunately we do not have a solid schedule I could share with you.

    Since the EnDat2.1 and BiSS-C are only available as a demonstration libraries (in controlSUITE) the i/o usage will be mostly fixed. The design guide for each has a table that details which signals can be modified outside of the library.
