CCS/DRV8846EVM: Using CCS to control DRV8846EVM

Matthew Pellioni
Prodigy 30 points
Part Number: DRV8846EVM

Tool/software: Code Composer Studio

I'm trying to control the DRV8846EVM-CB motor controlling board using CCS. I am able to properly operate the board and a motor with the board GUI, however I need to be able to operate the board using CCS. I have imported the downloaded project sllc446a into CCS, however I cannot get the board to connect and communicate with the CCS software, and the imported project fails to build. Please help me, I am also a new CCS user so any help with running it would be greatly appreciated. Thanks

    Matthew,

    Do you use a MSP430F2617TPMR launch pad to connect the computer and the EVM board?

    No, I'm plugging into the computer directly using a usb because this is how I was controlling it with the device specific GUI

    Matthew,

    The firmware preloaded to MSP430 to support GUI communication with a simple USB.

    But, to burn a new CCS firmware into the microcontroller, the program FETPro430 Lite from ElProtonic can be used.
    1. Step one: use CCS to generate MSP430 firmware txt file.
    2. Find FET-Pro430-Lite-Setup.zip (version 3.2-0) and Install it.
    3. Using a USB A Male to Micro B Male connector, connect the PC to DRV8846EVM USB port, J6. The status LED, D2, on the DRV8846EVM may begin blinking; Connect the MSP-FET430UIF to your computer using an USB Cable.
    4. Open the program FETPro430 Lite and load the txt file and program the txt file to MSP430.

    This EVM was designed long time ago. I don't think it can support CCS online programming and debugging easily.

    Matthew,

    I got one good news and one bad news from our senior engineer.
    Good news: with MSP-FET430UIF, CCS can send out the code and do the debugging directly.
    Bad news: The MSP-FET430UIF box could cost $100.
