Driver ASCOM for dome, focusers and switch

Now I have developed all the others drivers for object controlled by Raspberry application. They are: dome, focuser1, focuser2, focuser3 and switch. All driver was checked with conformance checker and conformance document was generated.

Also in this case communication between driver and Raspberry is done via TCP/IP, using other ports. 

For these reason the Rapberry application was update, now its version is 1.2.0.0. In the resource is presente the new version.


You can find all new drivers and conformance documents in the resource.

Dome driver supports these features:

  • Slaved 

  • Home finding 

  • park 

  • Open/close shutter 

Focuser drivers support these features:

  • Absolute position

  • Maxposition and step configurable in Raspberry application

Switch driver supports these features:
  • Ready only analogue value with temperature in the dome

  • Read/write boolean value for flat field light

  • Read/write boolean value for telescope decondence fan

Driver ASCOM for telescope

 Because of Raspberry controller is able to manage different devices more Ascom driver are needed, one for each device. Now the first driver is developed using Microsoft Visual Studio, thanks to development tools supplied by Ascom Platform. Conformance checker was used to verify and validate it. Conformance document was generated.

Communication between driver and Raspberry is done via TCP/IP, Each driver uses its own port. Raspberry implement a UDP broadcast communication used to make know its IP address to the driver, in this way IP address can be discovered during the driver setup.


 These are the supported features:

  • Alignment: Polar
  • Sync and async target and coordinate Slewing
  • Target and coordinate Sync
  • Tracking: Sireal with the possibility set right ascension and declination rate
  • Move axis support
  • Topocentric equatorial system
  • Parking on local meridian at declination 0
  • Pulse guide support
  • Aperture area and diameter and focal length are from Raspberry controller where can be configured.
  • Observatory site location is from Raspberry controller where can be configured.

In the resource you can find driver setup and conformance document
