SendConfiguration Method - neoVI API

This method sends configuration information to the hardware.

int _stdcall icsneoSendConfiguration(int hObject, unsigned char *pData, int lNumBytes);

Parameters

hObject

[in] Specifies the driver object created by OpenNeoDevice.

pData

[in] This is an array configuration bytes. The format of this array is defined in the Configuration Array help topic. This data should be filled in with a call to GetConfiguration before calling SendConfiguration. The size of this array must always be 1024 bytes.

lNumBytes

[in] This must always be set to 1024.

Return Values

Returns 1 if successful, 0 if an error occurred. GetLastAPIError must be called to obtain the specific error. The errors that can be generated by this function are:

NEOVI_ERROR_DLL_NEOVI_NO_RESPONSE = 75

Remarks

This method will only update the configuration defined in the Configuration Array topic. It will also apply checking to the data so that a neoVI is not programmed to an illegal state. For example, setting the CAN controller to an illegal operating mode.

Examples

unsigned char bConfigBytes[1024];
int iNumConfigBytes = 1024;

   lResult = icsneoGetConfiguration(hObject, bConfigBytes, &iNumConfigBytes);
