NexStar Evolution/AUX driver updates - by: Jochym

There is an updated version of the NexStar Evolution / Celestron AUX driver in the repository.
It is not compiled in the standard packaging due to the early stage of the driver.
It is ready for careful testing. But please do not use it unattended.
It is not ready for remote autonomous operation.

The new version sports multiple bugfixes and some enhancements:
  • Better communication with support for different scope addresses
  • Config save/load
  • Par/Unpark/Abort support
  • GPS support
  • GPS emulator. If the host running the driver has gps driver running the NS Evo driver will respond
    to the hand controller requests for position and time. It works nice with RaspberryPi + GPS module.
    Even if you are not using the driver for scope control the HC gets position and time from the GPS.
    There is no UI for that functionality yet - but it just works if you connect the driver to the scope with HC connected.
    It works like replacement for the Celestron GPS module

Right now I am working on the implementation of two main features:
  • Movement limits / safety features
  • custom tracking rates in the driver. Particularly satellite tracking mode.
Watch this space.

At this moment I can really use some external testing. Be warned - this is beta level code.
Particularly it does not have movement limiting code implemented. Have your power switch ready.
Although there was no unexpected movements in my tests so far.
If you need help compiling the driver contact me.
It works on PC linux and Raspbian (RPi 2).

Comments/criticism/patches will be appreciated!
