CSEN - Capacitive Sense
Description
Capacitive Sense (CSEN) Peripheral API.
Provides functions for controlling the capacitive sense peripheral of Silicon Labs' 32-bit MCUs and SoCs. The CSEN includes a capacitance-to-digital circuit that measures capacitance on selected inputs. Measurements are performed using either a Successive Approximation Register (SAR) or a Delta Modulator (DM) analog to digital converter.
The CSEN can be configured to measure capacitance on a single port pin or to automatically measure multiple port pins in succession using scan mode. Also, several port pins can be shorted together to measure the combined capacitance.
The CSEN includes an accumulator which can be configured to average multiple conversions on the selected input. Additionally, an Exponential Moving Average (EMA) calculator is included to provide data smoothing. A comparator is also included and can be used to terminate a continuous conversion when the configured threshold condition is met.
The following example shows how to initialize and start a single conversion on one input:

Set the DM integrator initial value.
Sets the initial value of the integrator(s) for the Delta Modulation (DM) converter. The initial value for the ramp-down integrator has no effect if the low-frequency attenuation was not selected by the mode initialization function CSEN_InitMode() .

- Confirm CSEN is idle before calling this function.
- Parameters
-
[in] csen
A pointer to the CSEN peripheral register block. [in] up
An initial value for the ramp-up integrator. [in] down
An initial value for the ramp-down integrator. Has no effect if low-frequency attenuation is not configured.
◆ CSEN_Init()
void CSEN_Init | ( | CSEN_TypeDef * |

) |
Initialize CSEN.
Initializes common functionality for all measurement types. In addition, measurement mode must be configured. See CSEN_InitMode() .
