Arduino library for the ProtoCentral FDC2214 4-channel capacitance-to-digital converter breakout.
The FDC2214 is a 28-bit, 4-channel capacitance-to-digital converter from Texas Instruments that measures capacitance via the resonant frequency of an external LC tank. Suitable for proximity / touch sensing, gesture detection, liquid-level sensing, material analysis, and metal / thickness measurement. This library provides device init, per-channel configuration, single-channel and autoscan acquisition, raw 28-bit reads, and helpers for converting raw output to sensor frequency and capacitance.
