First Contact with InstaSPIN-FOC. Need help

Other Parts Discussed in Thread: DRV8302, DRV8301, DRV8303, MOTORWARE, INSTASPINUNIVERSALGUI

Hi,

first of all I'm new to that motor control stuff. We have to develop a FOC motor control solution so I'm looking where to start. I think I will get myself the Launchpad XL + the DRV8301-Booster Board to get in first touch with the topic.

May I still ask you some question before starting?

  • Which DRV83xx device should I chose for a new design? I understood that the difference between DRV8301 and DRV8302 is the changed SPI-IF but with DRV8303 it's back? Shall I stick with the DRV8303 if in doubt? I can't see any difference beside the IF!?
  • Is it possible to change the motor control parameters later on per protocol (SPI/UART/..)?
  • Is it still possible to run the Motorware GUI with one's own board? If yes: Is there anything special needed (i.e. some emulator?) or does it work out of the box via JTAG, just like the Eval-Board?

Thanks for your support in advance!

Kind regards,

Stephan

    I would use the DRV8301 simply because the SW is already included in MotorWare. I think the DRV8303 doesn't include the buck?

    Yes, for motor control parameters you can have them compile in, pull them from a look-up table / EEPROM, or pass them through a comms channel (assuming your embedded SW is built with this logic).

    Yes, if you are talking about the INSTASPINUNIVERSALGUI the variables are all common in MotorWare. As long as you have a JTAG header on your board you can use the GUI as is. If you add your own variables you can edit this GUI in CCS GUI Composer. You do need an emulator, you can put the FTDI chip on your board or just a JTAG header and use an external emulator.

    Hi Chris,

    thank you very much for your very precise answers! I really do appreciate this :)
    And yes, of course you were right: The DRV8303 does not include the buck-converter. Didn't see that earlier today - thanks for the hint!
    I will fight my way further through the motor jungle! :)

    Thanks a bunch!
