Part Number: LAUNCHXL-F28069M

hello,

I would like to control a small PMSM with Launchxl-f28069M and BOOSTXL-DRV8301. I would like a sensored  (encoder based) control, so I understand I have to use QEP module of  Launchxl-f28069M. I found that documentation for a sensored control is rare nowadays as sensorless in more common. nevertheless I found a document on PMSM control using Launchxl-f28377S.

Here is question,

I see in the document on PMSM control using Launchxl-f28377S that, project was taken from controlSUITE\development_kits\TIDM-SERVO-LAUNCHXS. can I use the same ccs project for controlling PMSM using Launchxl-f28069M?

thanks

  • You should be able to, but that would require porting the analog and digital IOs.

    The software for 377s device is written based on the GPIOs and analog inputs of that device on that board. When you want to use the same software on a different device on a different PCB, then it will have different pins doing the same job of the original board.

    Hence I mentioned that the software will have to be ported over to fit the new environment. Hope it helps.

    okay. I understand now. I am unable to buy Launchxl-f28377S as it seems its an obsolete product. is there any available launchpad whose architecture is same as Launchxl-f28377S so that I dont need to port?

  • In reply to Safwat Ahmed Choudhury:

    The 377s launch pad is replaced with 379d (part # LAUNCHXL-F28379D).

    However, you will still have to port, as you cant avoid it.

  • In reply to Ramesh Ramamoorthy:

    porting seems to be a difficult process from one launchpad to another. do you have any suggesion how to proceed or is there any documents that i can study?

    thanks
