TCA8418E-EVM: TCA8418E-EVM GUI: "Could not detect COM PORT"

Part Number: TCA8418E-EVM
Other Parts Discussed in Thread: MSP-EXP430G2ET, TCA8418E, MSP430G2553, TCA8418, MSP430FR6989

Hi,

I am running Eval board p/n TCA8418E-EVM with MSP-EXP430G2ET. After finding the right drivers, I was successful in using TCA8418E_Flasher.bat to program the supplied text file.

BUT, when launching setup.exe in TCA8418E-EVM GUI folder, I am getting "Could not detect COM PORT."

Any idea?

Thanks,

(PS:

I am using Windows 10 pro

For completeness, below is result of running the batch file, TCA8418E_Flasher.bat )

    Hey Khanh,

    I know that our IO Expander currently does not support the MSP430G2 launchpad (hoping to resolve this soon), this may be a compatibility issue with this your launchpad. The EVM user's guide mentions a version 1.5 of an older launchpad which I believe has been obsoleted. This may be the problem.

    Would you be able to use the launch pad to instead hook up the SDA/SCL lines to our TCA8418 EVM. I believe we may be able to provide some example code for you to use to try to evaluate our device with.

    Thanks,

    -Bobby

    Hi Bobby,

    Thank you for the info.

    If you don't mind, could you provide a sample code & instruction as a work-around of the eval bd's compatibility issue.

    Hope you can resolve the compatibility...soon.

    Thanks again.

    Hi Khanh,

    I wanted to add a link to some example code MSP430G2553 which can be found on the device's store page. This code is designed to work for this family of boards and can be flashed onto the device using TI's Code Composer Studio. This code does not include a Keypad specific example, but it does have an I2C example projects (msp430g2xx3_usci_spi_standard_slave.c) that will help interface with the EVM through I2C. Let me know if you have any questions about the code or its use. 

    Do you have access to another launchpad board? I believe I have some more fleshed out examples for MSP430FR6989 if you have access to one.

    Regards,
    Eric
