FDC1004EVM: FDC1004EVM

Part Number: FDC1004EVM
Other Parts Discussed in Thread: MSP430F5529, FDC1004, ENERGIA, FDC2214

Hi there,

I am trying to connect FDC1004 and the LaunchPad with the following guide: "Getting Started Guide: FDC1004 with MSP430F5529 LaunchPad".

Is it okay to download the most recent energia-1.8.7E21? I actually downloaded this, but have no idea where *Select “.ino” file* is.

Thanks,

    On the guide, it instructs as follow;

    "Energia & the Code
    1. Download Energia - http://energia.nu/download/
    2. Open Program in Energia – File -> Open -> *Select “.ino” file*
    3. Plug in LaunchPad via USB and Connect
    i. Tools -> Board -> Launchpad w/ msp430f5529 (16MHz)
    ..............."

    I am trying to open program in Energia as instructed by #2. There are number of ".ino" files under the example fold, but have no idea which file should be open for my purpose to read capacitance at the maximum speed by FDC1004? The manual says that it is available to collect data at the sampling rates of 100 samples/second, 200 samples/second, or 400 samples/second using FDC1004.

    Tae,

    Can you link to the guide that you are referring to?

    Hi Clancy,

    Would you give me some comments about this matter?

    Thank you,

    Clancy,

    Actually I talked a lot with your fellow to solve this issue in collecting data at the maximum sampling rate as mentioned on the manual. Then your fellow finally suggested me to use this launch pad. Hope you help me in this issue. 

    Thank you,

    Thank you for your patience. I found the history that you are referring to.

    To answer your original question, I only see one .ino file that you can use. It is called "CapacitiveSensingSampleCodeEnergia.ino".

    Energia has its own "example" folder, but you need to navigate to where the TI provided file is. It should be in the following folder:

    C:\ti\Capacitive Sensing Microcontroller Sample Code (Energia)-1.1

    Clancy,

    As you mentioned, I tried to download a file from "C:\ti\Capacitive Sensing Microcontroller Sample Code (Energia)-1.1",but it is only the single file of "snvc187a". Would you please check this once again.

    Thank you,

    Hi Clancy,

    Are you able to send me the "CapacitiveSensingSampleCodeEnergia.ino" directly? It may help us to speed up in solving this issue. 

    Thank you,

    Did you unzip the snvc187a file? Everything should be in there. In fact, that is how I verified the file names.

    Our newer devices actually significantly reduce the noise in a capacitive measurement by using a different measurement technique. The FDC2214 is something that you can look at.

    Yes, it was unzipped. However, it is a single file "snvc187a". The original file is "snvc187a.winRARArchive". If you have simply taken a part from a package, can you send me the cord you are suggesting? It is more easy to save my time and yours.

    As you recommend, I am investigating the FDC2214. I would like ask you once again about the origin of noise. Can you share with me about the origin of the noise?

    Thank you,

    It seems that my desk top is so old. It is why I could not see anything beyond the single file. Anyway, it was opened and show "CapacitiveSensingSampleCode-1.1-windows-installer".

    Hi Clancy,

    As the guide instructed, the launchpad and FDC1004 have been connected each other and uploaded the firmware. Then, finally COM4 window appeared after completion of uploading. There is nothing in the COM4 window. What should I do to control the speed of sampling in measurement of capacitance? If there is user's guide in operating energia, specifically for my purpose, would you please let me know?

    Thank you,

    TB

    The code is well commented. I found a section where you can change the SPI baud rate on line 34, although I do not recommended changing anything until you confirm you are able to stream data.

    Have you followed the user's guide step-by-step? If you are still having issues, you can reach out for Energia specific support.
