ReadWritePhySettings Method - neoVI API

PreviousGetPerformanceParameters Method - neoVI APINextEnableDOIPLine Method - neoVI API

Last updated 2 years ago

This method allows reading and writing the PHY settings from/to the hardware.

int _stdcall icsneoReadWritePHYSettings(void * hObject, PhyRegPkt_T *PHYSettings, size_t Size, size_t NumEntries);
Public Declare Function icsneoReadWritePHYSettings Lib “icsneo40.dll” (ByVal hObject As IntPtr, ByRef PHYSettings As PhyRegPkt_T, ByVal iSize As IntPtr, ByVal NumEntries As IntPtr) As Int32
[DllImport(“icsneo40.dll”)] public static extern Int32 icsneoReadWritePhySettings(IntPtr hObject, ref PhyRegPkt_T PHYSettings, IntPtr iSize, IntPtr NumEntries);

Parameters

hObject

[in] Specifies the driver object created by .

PHYSettings

[out] This is the address of the first element of an array of structures. This array will be loaded by the application software with entries to be read or written from/to the hardware.

iSize

[in] Specifies the size of the structure used by the application. This is to make sure the structure used in the application and the DLL is same to avoid any buffer overrun.

iNumEntries

[in] Specifies the number of PHY Entries to be read or written.

Return Values

Returns 1 if successful, 0 if an error occurred. must be called to obtain the specific error.

Remarks

This function call sends the PHY Entries to be read or written from/to the hardware.

Examples

PhySettings.clause22.phyAddrOrPort = 0x6;
PhySettings.clause.regAddr = 0x2;
PhySettings.clause.pageOrDevice = 1;
PhySettings.WriteEnable = 0;
PhySettings.Enabled = 1; //if not enabled, this entry of read/write operation will be ignored even if it is passed in.
PhySettings.Clause45Enable = 0; //Set this to 1 if the application is sending Clause45 type of Entries.

icsneoReadWritePHYSettings(handle, &PhySettings, sizeof(PhyRegPkt_t), 1);
Int32 iResult;

iTempFlags = iTempFlags | (int)PhyRegFlags.Enabled;
iTempFlags = iTempFlags | (int)PhyRegFlags.Clause45Enable;
PhyRegPkt.Flags = (ushort)iTempFlags;

//Get and cast the size of the structrue.
