Other Parts Discussed in Thread: TMS320F28335, MOTORWARE, INSTASPIN-BLDC, CONTROLSUITE

Hi,

   i am using TMS320F28335 DSC for most of my motor control applications so i dont want to change the controller but still i would like to use the instaspin

technology. the following are my questions

1. why cant this technology applied to F28335?.

2. i would like to get the source code of insta spin library and make it compatible to F28335 Controller. is it possible or not?

Regards,

Namasivayam G

    1. InstaSPIN-FOC and InstaSPIN-MOTION are enabled by special libraries which - for protection purposes - are only built onto the memory of specific devices we want to support. To date this is the Piccolo F2806x, F2805x, and F2802x series.

    2. No, we do not release source code or libraries of the core functions in InstaSPIN-FOC or -MOTION.  MotorWare contains all the public code we release.

    InstaSPIN-BLDC is a slightly different story as it is delivered in a library format. It already runs on any F28x device (and was also ported to run on our ARM MCU families).  It was not built for FPU support though, so if you used on an F28335 you couldn't use FPU anywhere in your system.

    Hi ,

    Thanks for the reply. Please respond to my below question

    1.Motor wave software is a special libraries which need to be build onto the memory of MCU?

    2.Motor wave software is compatible to F28335 or we need update source code of Motor wave software to make it to work with F28335.

    3.will you deliver source code of microwave software or InstaSPIN-BLDC library?

    Regards,

    Namasivayam G

    1. MotorWare is the software distribution system for InstaSPIN-FOC and -MOTION. It includes all the source code, public libraries, and API to access the on-chip ROM libraries. You use the project examples to compile a project which is downloaded to the Flash or RAM of the target MCU.

    2. InstaSPIN-FOC and -MOTION are not compatible with F28335. Many of the MotorWare drivers and modules could be used on F28335, but obviously these would just be generic pieces of code. None of the project will run on F28335.

    3. No, source code is not provided for InstaSPIN-BLDC, only the .lib included in the controlSUITE examples.

    InstaSPIN-BLDC can be used in AIR born products (Flight products)? This InstaSPIN-BLDC library can be / is ceritified to compliance with aero standards?

    that depends on the certification requirements. I know that some flight certifications require archival of all source code (even if a library is used in the system) so if that's the case InstaSPIN-BLDC could not be used.

    Thanks for your reply.

    I would like to use Instaspin-BLDC  in F28335 by disable the FPU(Floating point unit) but i want to use iqmath to overcome FPU disabling.

     The above condition are ok to use Instaspin-BLDC  in F28335?
