IOLM_SMI_CBGenericCnf

IOLM_SMI_CBGenericCnf

SMI Generic request confirmation callback.

This callback function is called by the stack for a generic access of all services of the SMI. Confirmation to the IOLM_SMI_vGenericReq request.

Parameters

[in]	psuHeader_p	Header.
[in]	pu8ArgBlock_p	Generic ArgBlock.

Example

void IOLM_SMI_vGenericCnf(IOLM_SMI_SHeader *psuHeader_p, INT8U *pu8ArgBlock_p)
{
    IOLM_SMI_SGeneralArgBlock *psuGenericArgBlock;
    INT8U u16ArgBlockLength = psuHeader_p->u16ArgBlockLength;
    psuGenericArgBlock = malloc(u16ArgBlockLength);
    ...
 
    // Get header parameters

IOLM_SMI_CBLoadMasterIdentification

IOLM_SMI_CBLoadMasterIdentification

Load Master configuration callback callback.

This callback service is called by the stack and requests the Master configuration from the application. Since this is hardware specific, it has to be implemented in the application code.

Parameters

[in]	u16ArgBlockLength_p	Length of the ArgBlock.
[in]	pu8ArgBlock_p	Data pointer which points to the Master identification (IOLM_SMI_SMasterident).

Example

void IOLM_SMI_vLoadMasterIdentification(INT16U *u16ArgBlockLength_p, INT8U *pu8ArgBlock_p)
{
    IOLM_SMI_SMasterident *psuMasterIdent = (IOLM_SMI_SMasterident *)pu8ArgBlock_p;
 
    psuMasterIdent->u16ArgBlockID = IOLM_SMI_ENDIAN_16(IOLM_SMI_eArgBlockID_MasterIdent);
    ...
 
    // ToDo: Set up psuMasterIdent parameters
}

IOLM_SMI_CBLoadNVCfg

IOLM_SMI_CBLoadNVCfg

Load configuration callback.

This callback service is called by the stack and requests the saved configuration struct from non volatile memory. Since this is hardware specific, it has to be implemented in the application code.

Parameters

[in]	u8Instance_p	0-x for DataStorage Port and 0xFF for SMI configuration.
[in]	pu8Data_p	Pointer to the configuration struct to be loaded (IOLM_SMI_SNVConfiguration).
[in]	pu32Length_p	Pointer to the length of the configuration struct.

Example

void LOLM_SMI_vLoadNVCfg(INT8U u8Instance_p, INT8U *pu8Data_p, INT32U *pu32Length_p)
{
    // Create local configuration struct in your application
    IOLM_SMI_SNVConfiguration sNVConfiguration;
 
    // Load configuration from non-volatile memory into struct
    // ToDo: Insert hardware specific code here
 
    // Copy configuration to pu8Data_p for the stack
    memcpy(pu8Data_p, &sNVConfiguration, *pu32Length_p);
}

IOLM_SMI_CBSaveNVCfg

IOLM_SMI_CBSaveNVCfg

Save configuration callback.

This callback service is called by the stack and is used to save the configuration struct to non volatile memory. If this function is finished writing the data it must call IOLM_SMI_vSaveNvFinished to notify the stack. Since this is hardware specific, it has to be implemented in the application code.

Parameters

[in]	u8Instance_p	0-x for Data Storage port and 0xFF for SMI configuration.
[in]	pu8Data_p	Pointer to the configuration struct to be saved (IOLM_SMI_SNVConfiguration).
[in]	u32Length_p	Length of the configuration struct.

Example

void LOLM_SMI_vSaveNVCfg(INT8U u8Instance_p, INT8U *pu8Data_p, INT32U u32Length_p)
{
    // Create local configuration struct in your application
    IOLM_SMI_SNVConfiguration *psuNVConfiguration = (IOLM_SMI_SNVConfiguration *)pu8Data_p;
 
    // Save configuration to non-volatile memory
    // ToDo: Insert hardware specific code here
 
    // Tell the stack that saving the configuration is finished
    IOLM_SMI_vSaveNvFinished();
}

IOLM_SMI_CBSMIExt

IOLM_SMI_CBSMIExt

SMI extension function callback.

Callback for extension functions which are proprietary and not included in the IOL/IOLW specification. Can be used for additional application specific services, firmware updates, etc. Since this is hardware specific, it has to be implemented in the application code.

Parameters

[in]	u8Instance_p	Instance (defined by caller).
[in]	pu8Data_p	Pointer to the response data.
[in]	u16Length_p	Length of the response data

Example

void IOLM_SMI_vExtensionService(INT8U u8Instance_p, INT8U *pu8Data_p, INT16U u16Length_p)
{
    IOL_EErrorType eErrorResponse;
    INT8U *pu8DataResponse;
 
    // ToDo: Insert application specific code here
 
    // Response to stack
    IOLM_SMI_vExtRsp(eErrorResponse, pu8DataResponse, 0);
}

void IOLM_SMI_vExtRsp	(	IOL_EErrorType	eError_p,
		INT8U *	pu8Data_p,

	)

SMI extension response.

Responses of extension functions which are proprietary and not included in the IOL/IOLW specification.

Parameters

[in]	u16Length_p	Length of the response data

Example

void IOLM_SMI_vExtensionService(INT8U u8Instance_p, INT8U *pu8Data_p, INT16U u16Length_p)

IOLM_SMI_vGenericReq()

IOL_FUNC_DECL void IOLM_SMI_vGenericReq	(	IOLM_SMI_SHeader *	psuHeader_p,
		INT8U *	pu8ArgBlock_p
	)

SMI generic request.

The function is used for a generic access of all services of the SMI. The answer to this request is the callback function IOLM_SMI_CBGenericCnf.

Parameters

[in]	psuHeader_p	Header.
[in]	pu8ArgBlock_p	Generic ArgBlock.

Example

// Allocate header memory
INT8U au8HeaderMem[sizeof(IOLM_SMI_SHeader)];

// Allocate ArgBlock memory (pu8Data contains the data of length u16DataLength)
INT16U u16ArgBlockLength = sizeof(IOLM_SMI_SGeneralArgBlock) + u16DataLength;
INT8U au8ArgBlockMem[u16ArgBlockLength];
IOLM_SMI_SGeneralArgBlock *psuArgblock = (IOLM_SMI_SGeneralArgBlock *)au8ArgBlockMem;
 
// Fill header
psuHeader->u16ArgBlockLength = u16ArgBlockLength;
