Description

Low Energy Sensor (LESENSE) Peripheral API.

This module contains functions to control the LESENSE peripheral of Silicon Labs 32-bit MCUs and SoCs. LESENSE is a low-energy sensor interface capable of autonomously collecting and processing data from multiple sensors even when in EM2.

struct	LESENSE_CoreCtrlDesc_TypeDef
	Core control (LESENSE_CTRL/CFG) descriptor structure.

struct	LESENSE_TimeCtrlDesc_TypeDef
	LESENSE timing control descriptor structure.

struct	LESENSE_PerCtrlDesc_TypeDef
	LESENSE peripheral control descriptor structure.

struct	LESENSE_DecCtrlDesc_TypeDef
	LESENSE decoder control descriptor structure.

struct	LESENSE_Init_TypeDef
	LESENSE module initialization structure.

struct	LESENSE_ChDesc_TypeDef
	Channel descriptor structure.

struct	LESENSE_ChAll_TypeDef
	Configuration structure for all the scan channels.

struct	LESENSE_AltExDesc_TypeDef
	Alternate excitation descriptor structure.

struct	LESENSE_ConfAltEx_TypeDef
	Configuration structure for the alternate excitation.

struct	LESENSE_DecStCond_TypeDef
	Decoder state condition descriptor structure.

struct	LESENSE_DecStDesc_TypeDef
	Decoder state x configuration structure.

struct	LESENSE_DecStAll_TypeDef
	Configuration structure for decoder.

	Configure a single LESENSE sensor channel.

void	LESENSE_AltExConfig (const LESENSE_ConfAltEx_TypeDef *confAltEx)
	Configure the LESENSE alternate excitation modes.

void	LESENSE_ChannelEnable (uint8_t chIdx, bool enaScanCh, bool enaPin)
	Enable/disable LESENSE scan channel and the pin assigned to it.

void	LESENSE_ChannelEnableMask (uint16_t chMask, uint16_t pinMask)
