How to add KeySight Laser interferometer to EPICS

[l123173 via Tech-talk <tech-talk at aps.anl.gov>]

Hi all,

       I have a Laser interferometer of KeySight 5519A/B，which data was collected through E1735A.

       I met two question when i try to put E1735A in EPICS.

       1) E1735A only has dll, the dll run in windows. 

            I don't know how to add the dll in epics and i have both win epics and linux epics.

       2) The dll has some function, which we have to use.  

           The function return the point of values buffer and the number of values.  The number of values was changed according the interval time. The function could send 255 values most each time. And we must invoke it frequently.

           So i think it is not possibile to transfer these values to pv using pyepics.

 

        Does anyone know how to solve it. Any suggesion was appreciate.

Regards,
Liang

The function:

int E1735A_ReadAllSamples(TLaserSample* pBuf, int BufSize)

typedef struct {

             double LaserPos;  //sample value

             __int64 TimeStamp;  // time stamp

             int LaserTriggerl;    //trigger

             int LaserError;       //error code

} TLaserSample
