LaunchXL-F28027 vs the F28027F

Other Parts Discussed in Thread: LAUNCHXL-F28027F, BOOSTXL-DRV8301, LAUNCHXL-F28069M

Howdy Everybody,

I bought a F28027 not the F, with a BLDC motor control board.  Now that I am getting closer to figuring it out, I noticed that I may have the wrong board as when I originally looked into it the BLDC board said any LaunchXL.

My project that I want to do is a mechanical cutting cow.  (basically a stuffed cow on a rope and pulley system) It just goes back and forth down the fence at varying speeds not real sophisticated.  Will the non F code LaunchXL still do the trick or should I order a F code? 

My end goal is to have a bluetooth remote or make a android app to control it.  Either run a pre programmed file or remotely control it from as far away as 300'

This is essentially what it is  

Thanks for the help!!

    well, this is a first :) but the application seems really straight forward.

    you need the "F" version to take advantage of the InstaSPIN-FOC solution as some of the library is in on-chip memory of the "F" devices.

    more importantly you need to understand what motor you are trying to control (3-ph BLDC hopefully; what voltage and current?) to first choose the proper inverter hardware. The LAUNCHXL-F28027F and all the software is mean to work with the 24V/10A BOOSTXL-DRV8301. You can certainly wire it up to another inverter, but if one of our others already fits your needs I'd just start with one of those.

    I am using the BOOSTXL-DRV8301, I have a 24VDC 3 phase brushless DC 8 amp max motor. I guess I just missed the part where the F code was the proper one, I guess I will need to order a F code. I looked over the InstaSPIN and it seems to make the project much simpler. Ill have an extra LAUNCHXL then!

    uh, yeah, it makes it MUCH easier than trying to write your own motor control software.
    This motor is perfect for the LP+BP combination.

    Another option is the LAUNCHXL-F28069M that we just released today. Will accept the same BOOSTXL-DRV8301 and supports InstaSPIN-FOC and InstaSPIN-MOTION. Plus - it will allow you to plug in a different BoosterPack if you wanted to try integrating more functionality onto the Piccolo MCU.

    Thanks Chris!!

    I will get one ordered up, must be the new at Mouser as they have it listed for $35, I will just order one direct from TI.  To bad they don't have a store up there as I was in Allen this weekend and drove right by.  Yeah the less code I have to write the better as it still kicks my butt about everytime.  I have a lot of learning to still do.
