FDC1004EVM: Matlab code

Mohammed Siraj Ghouri

Part Number: FDC1004EVM

Hello everyone,

I want to use Matlab as a GUI instead of the GUI provided by TI.

I am able to read the capacitance values butI am not able to figure out how to change the CAPDAC settings.

I would be grateful for any help with Matlab.

Best regards,

Siraj

    Hello Mohammed,

    Unfortunately we do not work with Matlab, but some of our community members may be able to provide some insight.

    Hello Yibo,
    Thank you very much for the reply.
    I actually wanted to know, if I want to use a GUI other than GUI provided by TI what would be the commands.
    For example, both in Matlab and also Hyperterminal i found the following settings:
    Command Result
    1 A single set of capcitance values of all the input pins.
    5 Data stream start.
    6 Data stream stop.
    7 Decreases conversion time.
    8 Increases conversion time.
    9 Changes orientation of the input pins(left to right).

    In the same way i wanted to know,what would be the commands of enabling and changing the CAPDAC values.
    Best regards,
    Siraj

    Hi Mohammed,

    In order to change the CAPDAC for any channel, you need to set the CHB bits [12:10] of the appropriate measurement configuration register to b100, and set the CAPDAC bits [9:5] to the desired value (from b00000 to b11111).

    You can find more information in the datasheet.
