  • FDC2214: FDC2214 gives wrong capacitance when AC pump is turn on and off

    Part Number: FDC2214 We have been using FDC2214 to stabilize the water level inside a large barrel by measuring the capacitance between two horizontal copper tapes glued outside the barrel. When the water level is too low, the MCU turns on AC pump to…

  • FDC2214: Errors in the datasheet

    TI Thinks Resolved
    Part Number: FDC2214 Hi, I am developing a driver for the Fdc2214 chip and have two uncertainties for the datasheet: 1. What is the correct deglitch filter setting for 33MHz? Table 11 on page 21 says 0b011 while the Mux_Config register says 0b111 2.…

  • FDC2214-Q1: Read Data from FDC2214-Q1 with STM32F4

    TI Thinks Resolved
    Part Number: FDC2214-Q1 Other Parts Discussed in Thread: FDC1004-Q1 Hello everyone. I am new members your community also TI. So how can I print the data from the FDC22214-Q1 sensor to the screen with I2C and STM32F4 DISCO card. If you share example code…

  • FDC2214: long wire optimization

    TI Thinks Resolved
    Part Number: FDC2214 Hello, I'm trying to measure a capacitor over 2 seperate 1,5m long wires. Each wire is shielded and connected to GND. At 20nF the results are good. At larger capacitances (e.g.) 40nF and, the signals amplitude can't be raised above…
