LESENSE - Low Energy Sensor

Channel descriptor structure.

#include <em_lesense.h>

Data Fields
bool	enaScanCh
	Set to enable scan channel CHx.
bool	enaPin
	Set to enable CHx pin.
bool	enaInt
	Enable/disable channel interrupts after configuring all the sensor channel parameters.
LESENSE_ChPinExMode_TypeDef	chPinExMode
	Configure channel pin mode for the excitation phase of the scan sequence.
LESENSE_ChPinIdleMode_TypeDef	chPinIdleMode
	Configure channel pin idle setup in LESENSE idle phase.
bool	useAltEx
	Set to use alternate excite pin for excitation.
bool	shiftRes
	Set to enable result from this channel being shifted into the decoder register.
bool	invRes
	Set to invert result bit stored in the SCANRES register.
bool	storeCntRes
	Set to store counter value in the RAM (accessible via RESDATA) and make the comparison result available in the SCANRES register.
LESENSE_ChClk_TypeDef	exClk
	Select clock used for the excitation timing.
LESENSE_ChClk_TypeDef	sampleClk
	Select clock used for the sample delay timing.
uint8_t	exTime
	Configure the excitation time.
uint8_t	sampleDelay
	Configure the sample delay.
uint16_t	measDelay
	Configure the measure delay.
uint16_t	acmpThres
	Configure the ACMP threshold or the DAC data.
LESENSE_ChSampleMode_TypeDef	sampleMode
	Select if the ACMP output, the ADC output or the counter output should be used in comparison.
LESENSE_ChIntMode_TypeDef	intMode
	Configure the interrupt generation mode for the CHx interrupt flag.
uint16_t	cntThres
	Configure the decision threshold for the sensor data comparison.
LESENSE_ChCompMode_TypeDef	compMode
	Select the mode for counter comparison.
