I've added a driver to the tree for the NexDome observatory dome. NexDome is located in the 3rdparty tree, it could have gone into the main branch but, I plan to add firmware update capability for the dome controller which will involve carrying hex files along with the driver, hence the placement into the 3rdparty tree.

NexDome is an affordable 2.2 meter observatory dome. The controller to rotate the dome is shipping, the controller for the shutter is in prototype form and not yet shipping, but should be real soon now.

The dome controller is based on an arduino leonardo, for which I wrote the firmware to control the dome.

We currently have one dome installed here, and will be installing a second one in the very near future as we finish construction on our 'his and hers' observatory setup. We live in a rural area on northern vancouver island, under a fairly dark sky. The domes are located about 420 feet from the house, and we put an optical fiber data link between the dome platforms and the house, so it can all be operated remotely.

NexDome folks took a different tack than most astro companies with regards to automation. When I first met them a little over a year ago, they said the goal was an entirely open source solution so that folks so inclined, can tinker with the setup as much as they want. So, the controllers are based on an arduino leonardo type of board, and the firmware for the controllers is all on github. All the drivers have been made available in source form on github as well.

This is a first release, there will be more updates over time as we add capabilities to the system.

Last night i updated my Leonardo and installed the NEXDOME driver on INDI and also the NEW version on Windows...

First, when testing INDI, and after having issues with my mount, i decided to test the NEXDOME implementation, it connects to the board, i start homing the dome, the sensor stops the dome on the right place but somehow the board is not sending the message to the driver saying AT HOME!!! so i can't use the dome!!!!
I had used the dome before from SGP using the ASCOM driver, all fine, but now with the new firmware and ascom driver i have the same problem, it starts the homing procedure, stops at the sensor, doesn't report back to ASCOM that it is there, so it never enables the calibrate button....
Don't know how to get error codes or log from INDI but managed to get this from the ASCOM SGP error window.

ee the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

After homing the dome, if you move it by one degree using the indi control panel, does it then show 'at home' ? If that gets the dome showing 'at home', then you should be able to proceed from there. FYI, once the dome has been calibrated, doesn't matter if it was done from indi, or something else, that calibration is stored in the controller and it wont need to be re-calibrated. The 'AtHome' return is only required for start of calibration with the V1.10 dome firmware. Once it's calibrated, handling of the home sensor is internal to the controller, and it syncs itself properly when the magnet passes the sensor. There is no need to be 'athome' for any of the operattions after that.


There is another firmware update _almost_ ready that changes handling of the magnet detection on the home sensor somewhat in a way that we no longer need to start the calibration from the 'at home' position, but I cant finish testing it today because a storm has rolled in and the dome has wind locks on today
