FDC2214: FDC2214 issue

The raw data will become large and large even the target object is still.
And it´s no effect when I use active shield or passive shield.
How do I improve it?

    Tom,

    Thank you for your post and your interest in TI products.
    I tried using one of our EVMs with the default settings and streaming raw data for channel 2, and could not reproduce what you are seeing.

    Are you using our EVM with the on-board sensors and default settings?
    If not, what is the set-up used to create the DATA plot?
    Regards,
    John

    Hi John,

    Thanks for your reply.

    Yes, I'm using your EVM and all settings are default.

    I test several times today, and first time it's very well.

    But the second it happens .

    Sometime is good, but sometime is bad.

    Can you tell me why or what I do something wrong?

    Thank you.
