LDC2112: LDC2112连接金属件

Hi Weixin,

Would it be possible for you to translate your question into English?

You might may also try asking your question on E2E China.

Thank you,

Chase Girard

1.The output DATAn registers (Addresses 0x02 through 0x09) of the LDC2112/LDC2114 contain the processed values of the changes in sensor frequencies.

What exactly does the processing value mentioned in the specification refer to? How is it processed?

2. We want to use the entire metal structural component as an inductor. Has there been any similar usage before? How should the registers be configured to adapt to the metal component?

Part Number: LDC2112

2.We intend to utilize the entire metal structural component as an inductor by directly connecting it to the LDC2112, expecting a numerical change upon touch without using a PCB inductor in between. Has there been any prior similar implementation? How should the registers be configured to adapt to the metal component?

3.Do you have the driver code for the LDC211x series? Could you please provide it?

Hi Weixin,

Thank you for your assistance.

1. The processing mentioned in the datasheet the how the algorithm interprets the data. Refer to section 7.3.3 - 7.3.5 in the datasheet for more information. For more details regarding the procession algorithms please refer to the document attached here.
2. Does the metal structure have an inductance that can be measured? The device is checking resonant frequency based on the LC tank circuit connected to the sensor. Please refer to section 1 to the document attached here.
3. No we do not have driver code for the LDC211x series.

I hope I was able to answer your questions. If you need any additional assistance please reply.

Thank you,

Chase Girard
