[SOLVED] Celestron slew rate with Joystick - by: Gorgias

Hello,

I am controlling my Celestron Nextar 8SE mount with a joystick. I know that in the Telescope simulator for example, it is possible to set the slew rate, to park/unpark the mount or abort the motion with buttons or axes of the joystick. However, I don't see those capabilities in the indi_celestron_gps driver, I can only set the "N/S/W/E Control".

In the file inditelescope.cpp, at the line 124, I see that:


And in the line 227 of the file celestrongps.cpp, the parameter nSlewRate is initialized to 9 through the method SetTelescopeCapability:


So the nSlewRate is higher than 4, so it should be possible to assign the joystick buttons/axes to the slew rate control?

If I want to add this capability, do I have to edit the C++ files, or is it possible to do it only with XML files? I have looked at the default XML config file of the celestron driver, and the part concerning the joystick control is the following:


So I have tried to add the button controls:


I do not get any error when loading the new XML config file, but the new options do not show up in the Celestron tab.
