phd2client

Sample client code for PHD2 server API - C++, C#, and python versions. If you need a different language binding please let me know.

C++

dependencies:

• jsoncpp
• libcurl

#include "guider.h"

// instantiate a guider object that will connect to PHD2 running on "localhost"
Guider guider("localhost");

// connect to PHD2
bool ok = guider.Connect();
if (!ok)
    std::cerr << "could not connect to phd2: " << guider.LastError() << std::endl;

// connect gear in the equipment profile named Simulator
ok = guider.ConnectEquipment("Simulator");
if (!ok)
    std::cerr << "could not connect equipment: " << guider.LastError() << std::endl;

// start guiding with settle tolerance of 2.0 pixels, 10 second settle time, 100-second timeout
ok = guider.Guide(2.0, 10.0, 100.0);

See phd2client.cpp for a more complete example.

C# (.NET)

using guider;

...
    using (Guider guider = Guider.Factory("localhost"))
    {
        try
        {
            // connect to PHD2
            guider.Connect();

            // connect equipment in profile "Simulator"
            guider.ConnectEquipment("Simulator");

            // start guiding with settle tolerance of 2.0 pixels, 10 second settle time, 100-second timeout
            guider.Guide(2.0, 10.0, 100.0);
         }
         catch (GuiderException ex)
         {
             // Guider exception
             Console.WriteLine("Guider Error: {0}", ex.Message);
         }
    }

python

from guider import Guider, GuiderException

...
    with Guider("localhost") as guider:
        try:
            # connect to PHD2
            guider.Connect()
