Compiler/LDC1101: LDC1101

user804961

Part Number: LDC1101

Tool/software: TI C/C++ Compiler

After setting and taking data using EVM of LDC1101, LDC1101 is connected to this CPU and controlled.
After setting, you can get RP_DATA only the first time. The rest will be 0.

The power supply voltage is 3.3V.
The content of STATUS is 0x1C, but 2 bytes from DATA_LSB (0x21) is 0.
I want to convert and read data continuously. What is the cause?

Hello,

Can you share your schematic and sensor details? It would be very helpful to have the following information:

1. Rp measurement of your coil at the resonant frequency of your LC tank. See here for instructions.

2. Oscilloscope captures of your sensor oscillations.

Best Regards,

Thank you very much.

We will send data using LDC1101EVM.

There are three types of coils, tests, and capacitors.

Tested with this circuit with the same content and a voltage of 3.3

The data cannot be retrieved successfully. Do I need to change the setting by changing the voltage?
