CSENEMLIB
Detailed 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:

Initialize a CSEN measurement mode.
Used to configure any type of measurement mode. After the measurement has been configured, calling CSEN_Enable() will enable CSEN and allow it to start a conversion from the selected trigger source. To manually start a conversion, use CSEN_Start() . To check if a conversion is in progress, use CSEN_IsBusy() , or alternatively use the interrupt flags returned by CSEN_IntGet() to detect when a conversion is completed.
- Note
- This function will stop any ongoing conversion and disable CSEN.
- Parameters

A pointer to the CSEN peripheral register block. [in] init
A pointer to the CSEN measurement mode initialization structure.

__STATIC_INLINE void CSEN_IntDisable | ( | CSEN_TypeDef * |
csen,
|
uint32_t |
flags
|
||
) |
Disable one or more CSEN interrupts.
- Parameters
-
[in] csen
Pointer to CSEN peripheral register block. [in] flags
CSEN interrupt sources to disable. Use a bitwise logic OR combination of valid interrupt flags for the CSEN module (CSEN_IF_nnn).

__STATIC_INLINE void CSEN_IntEnable | ( | CSEN_TypeDef * |
csen,
|
uint32_t |
flags
|
||
) |
Enable one or more CSEN interrupts.
- Note
- Depending on the use, a pending interrupt may already be set prior to enabling the interrupt. Consider using CSEN_IntClear() prior to enabling if such a pending interrupt should be ignored.
- Parameters
-
[in] csen
Pointer to CSEN peripheral register block. [in] flags
CSEN interrupt sources to enable. Use a bitwise logic OR combination of valid interrupt flags for the CSEN module (CSEN_IF_nnn).

__STATIC_INLINE uint32_t CSEN_IntGet | ( | CSEN_TypeDef * |
csen
|
) |
Get pending CSEN interrupt flags.
- Note
- The event bits are not cleared by the use of this function.
- Parameters
-
[in] csen
Pointer to CSEN peripheral register block.
- Returns
- CSEN interrupt sources pending. A bitwise logic OR combination of valid interrupt flags for the CSEN module (CSEN_IF_nnn).

__STATIC_INLINE uint32_t CSEN_IntGetEnabled | ( | CSEN_TypeDef * |
csen
|
) |
Get enabled and pending CSEN interrupt flags. Useful for handling more interrupt sources in the same interrupt handler.
- Parameters
-
[in] csen
Pointer to CSEN peripheral register block.
- Note
- Interrupt flags are not cleared by the use of this function.
- Returns
-
Pending and enabled CSEN interrupt sources. The return value is the bitwise AND combination of
- the OR combination of enabled interrupt sources in CSENx_IEN_nnn register (CSENx_IEN_nnn) and
- the OR combination of valid interrupt flags of the CSEN module (CSENx_IF_nnn).

Set one or more pending CSEN interrupts from SW.
- Parameters
-
[in] csen
Pointer to CSEN peripheral register block. [in] flags
