Function Documentation

phhalHw_Sam_Rc523_SetConfig()

phStatus_t phhalHw_Sam_Rc523_SetConfig	(	phhalHw_Sam_DataParams_t *	pDataParams,
		uint16_t	wConfig,
		uint16_t	wValue
	)

Set configuration parameter.

Rc523 Specific

Returns

Status code

Return values

PH_ERR_SUCCESS	Operation successful.
PH_ERR_UNSUPPORTED_PARAMETER	Configuration is not supported or invalid.
PH_ERR_INVALID_PARAMETER	Parameter value is invalid.
PH_ERR_PARAMETER_OVERFLOW	Setting the parameter value would lead to an overflow.
PH_ERR_INTERFACE_ERROR	Communication error.

Parameters

[in]	pDataParams	[In] Pointer to this layer's parameter structure.
[in]	wConfig	[In] Configuration Identifier.
[in]	wValue	[In] Configuration Value.

phhalHw_Sam_Rc523_Wait()

phStatus_t phhalHw_Sam_Rc523_Wait	(	phhalHw_Sam_DataParams_t *	pDataParams,
		uint8_t	bUnit,
		uint16_t	wTimeout
	)

Blocks until the time given by wTimeout elapsed.

Parameters

[in]	pDataParams	[In] Pointer to this layer's parameter structure.
[in]	bUnit	[In] Unit of given timeout value (either PHHAL_HW_TIME_MICROSECONDS or PHHAL_HW_TIME_MILLISECONDS).
[in]	wTimeout	[In] Timeout value.

phhalHw_Sam_Rc523_SetFdt()
