LDC1312EVM: Not reporting inductance/frequency on Sensing Solutions GUI

Part Number: LDC1312EVM

Hi Inductive Sensing Team,

One of my customers and me are having trouble with the LDC1312EVM; the device is not reporting inductance/frequency measurements on the Sensing Solutions GUI, only raw code. We tried flashing with the included TI-TXT firmware without any luck. Any suggestions? 

Regards,

Leo

  • Hi Leo,
    Note that the device only reports raw data which represents the frequency of the sensor in relation to the reference frequency. The GUI does a calculation to convert to inductance, but if you don't supply the correct capacitance value or have one of the divider values set to 0 or the entered clock frequency to 0 then it will give an incorrect or invalid result. If you're using the EVM then you can look at figures 24 and 25 of the LDC1312EVM user guide for example settings (www.ti.com/.../snou135).
    Let us know if this resolves the issue.
    Thanks!
    Luke
