TCA8418: TCA8418E-EVM & MSP-EXP430G2ET Interface

Part Number: TCA8418
Other Parts Discussed in Thread: MSP-EXP430G2ET, , , PCA9306EVM

Hi,

I am trying to evaluate TCA8418E-EVM Evaluation Module and MSP-EXP430G2ET Launchpad.                                 

We have Interfaced TCA8418-EVM with MSP-EXP430G2ET as per User guide. The FET drivers given by TI are installed successfully and there is no error while running the batch file.

But, I am facing issue with the TCA8418EEVM GUI which has to simulate the inbuilt Keypad with TCA8418 EVM.

Device manager is able to detect the com port (MSP Application UART1) But, The application is giving error as "Could not find COM PORT"

Find the Jumper settings we have made as shown in below image.

 

Can you please help us to resolve the issue?

 

Thanks and Regards,

Pedaiah G.

                                

  • Hi Pedaiah,

    I believe I worked on this issue twice before in which we found that the MSP430 EVM was not compatible with the GUI since the one used in the creation of the 8418EVM was made to work with a now obsolete MSP430 EVM.

    Do you have access to an arduino/arduino mega? I should have some code laying around that would allow you to interface with the 8418EVM if you have an arduino at hand. The set up to connect the arduino to the 8418 EVM would require a level translator though since arduino uses 5V logic and the 8418 doesn't support 5V.  We have a PCA9306EVM that can be used as a translator if you would like to go through this workaround.

  • Hello Bobby,

    Thank you. Noted.

    Do you have the Latest GUI which is compatible with latest MSP430 EVM and 8418EVM?

    Yes, We do have Arduino Board and use Level Translator as per your suggestion.

    Please provide the Code.

    Thanks and Regards,

    Pedaiah G.

  • Hey Pedaiah,

    Unfortunately we do not have any kind of update or new GUI that would work for the newer MSP430 modules.

    TCA8418.ino
    TCA8418_Keypad_read.ino

    Attached are the two arduino codes I could find on my PC for the 8418 device (compatible with the E version as well)

    Let me know if you need further help with either the hardware set up or need help debugging the software I provided.
