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