Other Parts Discussed in Thread: FDC1004

What is the actual material used as shield and reference, level sensor. 

And also, not able to download the firmware and gui  from the TI link. Can anyone help

    Hi Shirpriya,

    We used copper, but any other highly conductive material (such as aluminum) is fine to used for the shield and sensors.

    To download the GUI and software requires answering some usage questions. Are you getting the export approval link when you attempt to download?

    Regards,

    Hi Chris,
    We have a board with I2C interface. we have made a small PCB with FDC1004 on it, taking FDC1004 Evaluation Module as reference (schematics taken from your TI website).
    We have programmed the registers as per register settings given in section 3.7 of "EvaluBd FDC 1004 snau165.pdf" . And making calculations as per document eqaution 1 in SNOA958 (How to Calibrate FDC1004 for Liquid Level Sensing Applications ).
    Can you please tell us-
    1. what should be the value of (Hrl) as given in the equation 1 of SNOA958 (How to Calibrate FDC1004 for Liquid Level Sensing Applications ). We have taken a small cup(few centimeters) for the experiment.
    2. As we are using PCB with FDC1004 Evaluation Module as reference, LEVEL sensor & REFERENCE sensor is connected to which of the Cin inputs? Coz i perceive that only 2 sensors have been used as the said documents.

    Please get back to us soon.
    Thanks,
    ASP
