◆ S2LPGpioGetLevel()

OutputLevel S2LPGpioGetLevel ( S2LPGpioPin xGpioX )

Return output value (VDD or GND) of S2LP GPIO_x, when it is configured as digital output.

Parameters

xGpioX

Specifies the GPIO to be read. This parameter can be one of following parameters:

S2LP_GPIO_0: S2LP GPIO_0
S2LP_GPIO_1: S2LP GPIO_1
S2LP_GPIO_2: S2LP GPIO_2
S2LP_GPIO_3: S2LP GPIO_3

Return values

OutputLevel Logical level of selected GPIO configured as digital output. This parameter can be: HIGH or LOW.

Definition at line 226 of file S2LP_Gpio.c.

◆ S2LPGpioInit()

void S2LPGpioInit ( SGpioInit * pxGpioInitStruct )

Initialize the S2LP GPIOx according to the specified parameters in the pxGpioInitStruct.

Parameters

pxGpioInitStruct pointer to a SGpioInit structure that contains the configuration information for the specified S2LP GPIO.

Return values

None.

Definition at line 168 of file S2LP_Gpio.c.

◆ S2LPGpioIrqCheckFlag()

SBool S2LPGpioIrqCheckFlag ( IrqList xFlag )

Verifie if a specific IRQ has been generated. The call resets all the IRQ status, so it can't be used in case of multiple raising interrupts.

Parameters

xFlag IRQ flag to be checked. This parameter can be any value of IrqList.

Return values

SBool S_TRUE or S_FALSE.

Definition at line 417 of file S2LP_Gpio.c.

◆ S2LPGpioIrqClearStatus()

void S2LPGpioIrqClearStatus ( void )

Clear the IRQ status registers.

Parameters

None.

Return values

None.

Definition at line 402 of file S2LP_Gpio.c.

◆ S2LPGpioIrqConfig()

void S2LPGpioIrqConfig	(	IrqList	xIrq,
		SFunctionalState	xNewState
	)

Enable or disables a specific IRQ.

Parameters

xIrq	IRQ to enable or disable. This parameter can be any value of IrqList.
xNewState	new state for the IRQ. This parameter can be: S_ENABLE or S_DISABLE.

Return values

None.

Definition at line 303 of file S2LP_Gpio.c.

◆ S2LPGpioIrqDeInit()

void S2LPGpioIrqDeInit ( S2LPIrqs * pxIrqInit )

Deinit the S2LPIrqs structure setting all the bitfield to 0. Moreover, it sets the IRQ mask registers to 0x00000000, disabling all IRQs.

Parameters

pxIrqInit pointer to a variable of type S2LPIrqs, in which all the bitfields will be settled to zero.

Return values

None.

Definition at line 253 of file S2LP_Gpio.c.

◆ S2LPGpioIrqGetMask()

void S2LPGpioIrqGetMask ( S2LPIrqs * pxIrqMask )

Fill a pointer to a structure of S2LPIrqs type reading the IRQ_MASK registers.

Parameters

pxIrqMask

pointer to a variable of type S2LPIrqs, through which the user can read which IRQs are enabled. All the bitfields equals to zero correspond to enabled IRQs, while all the bitfields equals to one correspond to disabled IRQs. This parameter is a pointer to a S2LPIrqs. For example suppose that the Power On Reset and RX Data ready are the only enabled IRQs.

S2LPIrqs myIrqMask;

S2LPIrqGetStatus(&myIrqMask);

Then myIrqMask.IRQ_POR and myIrqMask.IRQ_RX_DATA_READY are equal to 0 * while all the other bitfields are equal to one.

Return values

None.

Definition at line 351 of file S2LP_Gpio.c.

◆ S2LPGpioIrqGetStatus()

void S2LPGpioIrqGetStatus ( S2LPIrqs * pxIrqStatus )

Fill a pointer to a structure of S2LPIrqs type reading the IRQ_STATUS registers.

Parameters

pxIrqStatus

pointer to a variable of type S2LPIrqs, through which the user can read the status of all the IRQs. All the bitfields equals to one correspond to the raised interrupts. This parameter is a pointer to a S2LPIrqs. For example suppose that the XO settling timeout is raised as well as the Sync word detection.

S2LPIrqs myIrqStatus;

S2LPGpioIrqGetStatus(&myIrqStatus);

Then myIrqStatus.IRQ_XO_COUNT_EXPIRED and myIrqStatus.IRQ_VALID_SYNC are equals to 1 while all the other bitfields are equals to zero.

Return values

None.

Definition at line 382 of file S2LP_Gpio.c.

◆ S2LPGpioIrqInit()

void S2LPGpioIrqInit ( S2LPIrqs * pxIrqInit )

Enable the IRQs according to the user defined pxIrqInit structure.

Parameters

pxIrqInit

pointer to a variable of type S2LPIrqs, through which the user enable specific IRQs. This parameter is a pointer to a S2LPIrqs. For example suppose to enable only the two IRQ Low Battery Level and Tx Data Sent:

S2LPIrqs myIrqInit = {0};
myIrqInit.IRQ_LOW_BATT_LVL = 1;
myIrqInit.IRQ_TX_DATA_SENT = 1;
S2LPGpioIrqInit(&myIrqInit);

Return values

None.

Definition at line 280 of file S2LP_Gpio.c.

◆ S2LPGpioSetLevel()

void S2LPGpioSetLevel	(	S2LPGpioPin	xGpioX,
		OutputLevel	xLevel
	)

Force S2LP GPIO_x configured as digital output, to VDD or GND.

Parameters

xGpioX	Specifies the GPIO to be configured. This parameter can be one of following parameters: S2LP_GPIO_0: S2LP GPIO_0 S2LP_GPIO_1: S2LP GPIO_1 S2LP_GPIO_2: S2LP GPIO_2 S2LP_GPIO_3: S2LP GPIO_3
xLevel	Specifies the level. This parameter can be: HIGH or LOW.

Return values

None.
