Page 6: Overview
The FDC2114/2214 EVM demonstrates the use of capacitive sensing technology to sense and measure the presence or position of target objects. The EVM contains two example LC tank sensors that are connected to the FDC2114/2214 input channels. The latter is controlled by an MSP430, which interfaces to a host computer. -
