  Using the QHY Filter Wheel INDI for Java Driver

Although the driver has been developed using the INDI for Java Library it can be used either with the standard indiserver of the original INDI Library or with the INDI for Java Server. In the following both methods are explained in detail. Please note that for both methods to work Java must be installed in your system.

 

  Method 1: QHY Filter Wheel INDI Driver Using the Standard indiserver
  1.  Download the INDI for Java QHY Filter Wheel Driver from the downloads page (I4JQHYFilterWheelDriver_vx.xx.zip).
  2. Unzip it to a directory of your choice:
    > unzip I4JQHYFilterWheelDriver_vx.xx.zip
  3. A directory called I4JQHYFilterWheelDriver must have been created. Enter into that directory. A file named launchQHYFWDriver.sh should be there:
    > cd I4JQHYFilterWheelDriver
    > ls -l
  4. Launch the standard indiserver with the launchQHYFWDriver.sh as parameter:
    > indiserver ./launchQHYFWDriver.sh
  5. The server (with the driver) should start working. Check it out with your favourite INDI Client.

  1. Download the INDI for Java Server from the downloads page (I4JServer_vx.xx.zip).

  5. Launch the INDI for Java Server with the QHY Filter Wheel Driver:
    > java -jar I4JServer/dist/I4JServer.jar -add=I4JQHYFilterWheelDriver/dist/I4JQHYFilterWheelDriver.jar
