Detailed Description

Contains Communication-Independent implementations of various hardwares.

These Components implement the interfaces between physical Host-Device and physical Reader-Device.

Function Documentation

◆ phbalReg_GetPortList()

phStatus_t phbalReg_GetPortList	(	void *	pDataParams,
		uint16_t	wPortBufSize,
		uint8_t *	pPortNames,
		uint16_t *	pNumOfPorts
	)

List all available ports.

Returns: Status code

Return values

PH_ERR_SUCCESS	Operation successful.
PH_ERR_BUFFER_OVERFLOW	Given enumeration buffer is too small.
PH_ERR_INTERFACE_ERROR	Error while enumerating devices.

Parameters

[in]	pDataParams	[In] Pointer to this layer's parameter structure.
[in]	wPortBufSize	[In] Buffer Size of Port Name String.
[out]	pPortNames	[Out] Port Name as Multi-String.
[out]	pNumOfPorts	[Out] Number of found port strings.

◆ phbalReg_SetPort()

phStatus_t phbalReg_SetPort	(	void *	pDataParams,
		uint8_t *	pPortName
	)

Select Port to be used.

Note: The caller has to ensure that pPortName is valid throughout the whole lifetime of pDataParams.
Furthermore, the caller is responsible for prepending \\.\ escape format if COM ports above COM9 need to be accessed.

Example:

strcpy(pPortName, "COM9");         <-- correct
strcpy(pPortName, "\\\\.\\COM9");  <-- correct
strcpy(pPortName, "\\\\.\\COM10"); <-- correct
strcpy(pPortName, "COM10");        <-- wrong

Returns: Status code

Return values

PH_ERR_SUCCESS Operation successful.

Parameters

[in]	pDataParams	[In] Pointer to this layer's parameter structure.
[in]	pPortName	[In] Port Name as String.

◆ phbalReg_OpenPort()

phStatus_t phbalReg_OpenPort ( void * pDataParams )

Open communication port.

Returns: Status code

Return values

PH_ERR_SUCCESS	Operation successful.
PH_ERR_USE_CONDITION	Communication port is already open.
PH_ERR_INTERFACE_ERROR	Error while opening port.

Parameters

[in] pDataParams [In] Pointer to this layer's parameter structure.

◆ phbalReg_ClosePort()

phStatus_t phbalReg_ClosePort ( void * pDataParams )

Close communication port.

Returns: Status code

Return values

PH_ERR_SUCCESS	Operation successful.
PH_ERR_USE_CONDITION	Communication port is not open.
PH_ERR_INTERFACE_ERROR	Error while closing port.

Parameters

[in] pDataParams [In] Pointer to this layer's parameter structure.

◆ phbalReg_Exchange()

phStatus_t phbalReg_Exchange	(	void *	pDataParams,
		uint16_t	wOption,

		uint16_t	wRxBufSize,
		uint8_t *	pRxBuffer,
		uint16_t *	pRxLength
	)

Perform Data Exchange on the bus.

Returns: Status code

PH_ERR_IO_TIMEOUT	No response received within given time frame.
PH_ERR_BUFFER_OVERFLOW	Response is too big for either given receive buffer or internal buffer.
PH_ERR_INTERFACE_ERROR	Communication error.

Parameters

[in]	pDataParams	[In] Pointer to this layer's parameter structure.
[in]	wOption	[In] Option parameter.
[in]	pTxBuffer	[In] Data to transmit.
[in]	wTxLength	[In] Number of bytes to transmit.
[in]	wRxBufSize	[In] Size of receive buffer / Number of bytes to receive (depending on implementation).
[out]	pRxBuffer	[Out] Received data.
[out]	pRxLength	[Out] Number of received data bytes.
