Make Life Accessible - Motor Suite Test - blog 8

dougw

This entry is a first exploration of the Kinetis Motor Suite capabilities, demonstrating motor reversing and sequencing through several states.

Next time I will try to hook up the Hall effect sensors to see if I can work at lower speeds.

  • Hi Doug

     

    I have a favour to ask you. I am roadtesting the FRDM-KV31, LVPMSM motor controller and Linix motor. After reading your design challenge blog, and downloading various documents, it is clear that getting these components to work with the Kinetis Motor Suite will depend on exactly the right combination of obsolete software. I also found that the KV31F boards come with different firmware, depending on their age.

     

    To save me hours of pain (like the 33+ hours you experienced), it would be great if you could firstly check what your KV31F board enumerates as when you plug it into a PC. This assumes a) you still have it, b) you can still find it!

     

    It should either show up as MBED <drive letter> , or FRDM-KV31F <drive letter>.

     

    Next, can you remember or have you a note of, which versions of:

    • Kinetis Motor Suite
    • Kinetis SDK

    worked with Kinetis Design Studio v3.0 and the hardware you were sent? I appreciate that almost three years have elapsed since this project.

     

    Any answers at all would help narrow down what I need! I asked NXP for some help but they said that they "will no longer be licensing" KMS and pointed me towards MCUXpresso (without KMS). I can do this, but I'd rather have a play with KMS first.

     

    Thanks in anticipation.

    Hi Steve,

     

    I've not used this board, Doug can comment way better than me, but if you wish to use it as a standalone board, or with your own code (appreciate it won't replace KMS) then mbed could be a nice general way to use the board.

    I have used mbed and KDS or its predecessor, on other FRDM boards - for the quickest results, mbed is worth using I think, although I liked KDS at the time too. I just have not used that recently, I always now use mbed for quick projects.

     

    For mbed, all the FRDM boards I've used have had old code on them that didn't work properly with Windows 10, so I wrote up what needed to be done here:

    Working with FRDM Boards and ARM mbed

    I don't have the FRDM-KV31 so can't check for you, but it could be worth scanning through that blog post, in case the "Upgrading the FRDM board Bootloader and OpenSDA Firmware" section there works for you. There is a file that seems suited for your board if you follow the links there:

    Sorry this isn't a complete answer since I've never used the motor board or KMS either : ( still, I hope the info helps to get the board running a hello world blinking LED etc., if you prefer that with mbed.

    Thanks Shabaz. I'll definitely give MBED a go but I want to have a look at KMS if I can get it working. It looks interesting just for its own sake.
