Parameters

DeviceTypes
    [in] Specifies the types of neoVI devices to find. Currently supported values are:

NEODEVICE_BLUE = 0x00000001
NEODEVICE_ECU_AVB = 0x00000002
NEODEVICE_DW_VCAN = 0x00000004

NEODEVICE_RED = 0x00000040
NEODEVICE_ECU = 0x00000080
NEODEVICE_IEVB = 0x00000100
NEODEVICE_PENDANT = 0x00000200
NEODEVICE_OBD2_PRO = 0x00000400
NEODEVICE_PLASMA = 0x00001000
NEODEVICE_CT_OBD = 0x00008000
NEODEVICE_ION = 0x00040000
NEODEVICE_RADSTAR = 0x00080000
NEODEVICE_VCAN44 = 0x00200000

NEODEVICE_VCANRF = 0x02000000
NEODEVICE_FIRE2 = 0x04000000
NEODEVICE_FLEX = 0x08000000
NEODEVICE_RADGALAXY = 0x10000000
NEODEVICE_RADSTAR2 = 0x20000000
NEODEVICE_VIVIDCAN = 0x40000000
NEODEVICE_OBD2_SIM = 0x80000000
NEODEVICE_ALL = = 0xFFFFBFFF

pNeoDevices
[out] This is the address of the first element of an array of NeoDevice structure. This array can be as big as 255 devices. You must specify the size of the pNeoDevices array in the pNumberOfDevices parameter. The number of devices found will be limited to the value of pNumberofDevices or 255, whichever is lower. Each returned NeoDevice structure will contain information for each device such as its type, device ‘handle’ and serial number.

pNumberOfDevices
    [in/out] In: Specifies the size of the pNeoDevices array. Must be in the range 0 to 255.
               Out: Specifies the number of neo devices that were found. This can be in the range 0 to 255.

Return Values

1 if the function succeeded. 0 if it failed for any reason. If the function succeeds but no devices are found 1 will still be returned and pNumberOfDevices will equal 0.

Remarks

The NeoDevice array elements that are returned with this function may be passed to OpenNeoDevice so that individual neoVI devices can be opened.

Examples

C/C++ Example:

NeoDevice Devices[255];
unsigned long lDevTypes;
int iNumDevices = 255;
int iRetVal = 0;  
int lDevTypes;  

lDevTypes = NEODEVICE_ALL;

iRetVal = icsneoFindNeoDevices(lDevTypes, Devices, &iNumDevices);  

C# Example:

int iResult;//Holds the results from function call
NeoDevice ndNeoToOpen = new NeoDevice(); ; //Struct holding detected hardware information
int iNumberOfDevices; //Number of hardware devices to look for
int lDevTypes; //Holds the device types to look for
lDevTypes = NEODEVICE_ALL;

//Set the number of devices to find
iNumberOfDevices = 1;
//Search for connected hardware
iResult = icsNeoDll.icsneoFindNeoDevices(65535, ref ndNeoToOpen, ref iNumberOfDevices);
if (iResult == 0)
{
    MessageBox.Show("Problem finding devices");
    return;
}

Visual Basic .NET Example:

Dim iResult As Integer '//Holds the results from function call
Dim ndNeoToOpen As NeoDevice '//Struct holding detected hardware information
Dim iNumberOfDevices As Integer '//Number of hardware devices to look for
Dim lDevTypes As Integer '//Holds the device types to look for

'//Set the devices to look for
lDevTypes = NEODEVICE_ALL
'//Set the number of devices to find
iNumberOfDevices = 1
'//Search for connected hardware
iResult = icsneoFindNeoDevices(lDevTypes, ndNeoToOpen, iNumberOfDevices)
If (iResult = 0) Then MsgBox("Problem finding devices")
