Anna Bridge 142:4eea097334d6 56 * This module provides functions for controlling the capacitive sense
Anna Bridge 142:4eea097334d6 57 * peripheral of Silicon Labs 32-bit MCUs and SoCs. The CSEN includes a
Anna Bridge 142:4eea097334d6 58 * capacitance-to-digital circuit that measures capacitance on selected
Anna Bridge 142:4eea097334d6 59 * inputs. Measurements are performed using either a successive approximation
Anna Bridge 142:4eea097334d6 60 * register (SAR) or a delta modulator (DM) analog to digital converter.
Anna Bridge 142:4eea097334d6 61 *
Anna Bridge 142:4eea097334d6 62 * The CSEN can be configured to measure capacitance on a single port pin
Anna Bridge 142:4eea097334d6 63 * or to automatically measure multiple port pins in succession using scan
Anna Bridge 142:4eea097334d6 64 * mode. Also several port pins can be shorted together to measure the
Anna Bridge 142:4eea097334d6 65 * combined capacitance.
Anna Bridge 142:4eea097334d6 66 *
Anna Bridge 142:4eea097334d6 67 * The CSEN includes an accumulator which can be configured to average
Anna Bridge 142:4eea097334d6 68 * multiple conversions on the selected input. Additionally, an exponential
Anna Bridge 142:4eea097334d6 69 * moving average (EMA) calculator is included to provide data smoothing.
Anna Bridge 142:4eea097334d6 70 * A comparator is also included and can be used to terminate a continuous
Anna Bridge 142:4eea097334d6 71 * conversion when the configured threshold condition is met.
Anna Bridge 142:4eea097334d6 72 *
Anna Bridge 142:4eea097334d6 73 * The following example shows how to intialize and start a single
Anna Bridge 142:4eea097334d6 74 * conversion on one input:
