MSP430F2619S-HT: could it be using to drive BLDC Sensor Less Motor ?

Part Number: MSP430F2619S-HT
Other Parts Discussed in Thread: MSP430FR2355, TIDA-010031, MSP-FET, MSP430F2619, MSP430WARE

Greetings,

I'd like to use MSP430F2619S-HT uController for driving BLDC motor ( sensor less). 

This project is very similar to TIDA-010031 based on MSP430FR2355 but I have to use MSP430F2619S-HT. 

Please advise.

Thank you,

Gadi Fishel

    Hey Gadi,

    After looking at the TID, it looks like you can use the F2619S. The FR2355 device features an integrated analog peripheral, but it doesn't seem to be utilized in this design:

    It looks like the MCU is utilized for its timers and ADC, so the F2619S should work.

    Thanks,

    Mitch

    Mitch,

    Thank you for response! ( Sorry didn't see it earlier) 

    The other question:

    I contacted BLDC Motor manufacturers and they said I should use sensor ( hall effect) for my application feedback - I have really high torque that could be problematic to reach ( or tune) using bEMF technique. 

    I suppose there are no issues to use MSP430F2619S for sensor feedback application as well. Am I right?

    Also I'd like try both solutions, could you please let me know  MSP430F2619S evaluation board p/n and what peripherals/ programmers should I purchase for it? Is its some learning material how to program MSP430F2619S?

    Thank you! and Looking forward to your response soon.

    Sincerely,

    Gadi Fishel

    Hi Gadi,

    Sorry for the delayed response. 

    There shouldn't be any issues using the F2619S for sensor feedback. One thing you will want to consider is to double check that you can achieve the required ADC sampling rate with the F2619S device. Otherwise, you should be ok.

    You will need a target socket board and MSP-FET programmer/debugger. This is sold as a bundle in the link below:

    There is also a 64 pin target socket board option as well if you plan on using that package. It looks like this is not sold as a bundle, so you will need to purchase the MSP-FET separately with this option:

    I am linking some resources I think might be helpful to you:

    http://www.ti.com/lit/ug/slau278ae/slau278ae.pdf - MSP-FET hardware user's guide

    https://software-dl.ti.com/ccs/esd/documents/users_guide/index.html - Code Composer Studio User's Guide

    There are also software examples in CCS for the F2619S device. In CCS, open Resource Explorer by navigating to View > Resource Explorer. Then go to Software > MSP430Ware > Devices > MSP430F2XX > MSP430F2619 > Peripheral Examples > Register Level. Here you will find a bunch of SW examples.

    Please let me know if you have any more questions.

    Thanks!
