LDC1614 / source code to calculate inductance value

Guru 29690 points
Other Parts Discussed in Thread: LDC1614

Hi Team,

I would like to ask about LDC1614 EVM.
I can see the inductance value(streaming data) on GUI when running EVM.

Could you give me the source code that is used to calculate the inductance value as a guide?
I checked the following files but can't find that.

Your support would be appreciate.

Best Regards,

  • Hello Yaita,

    The MSP430 FW does not calculate the inductance, it just reports the conversion code, which corresponds to the sensor frequency (refer to equation 8 in the datasheet for how to calculate sensor frequency from the output code). Equation 9 can be used to calculate L from the sensor frequency.

    You can also download the LDC tools spreadsheet from , which has an LDC output code calculator tab.

    Regards,
