Sounds good. It would be great if you create a pull request - or simply send me your modifications directly.

Pull request sent. Its now very stable although it still has a couple of small things to fix around that timing problem. I thought I read in the code that the ttyread timeout was in seconds but I'm not seeing that. Elsewhere I've seen the timeout for ttyread being in tenths of a second which corresponds to what I'm observing. Currently the StarGo driver is using a timeout of 5 - if that's 0.5s then I might need to up it to 10 (1s) as I'm seeing the occasional read timeout which sometimes triggers the same issue I've been sorting out.

I see you've been doing lot of great work on the StarGo driver ! Can you tell me where I can find the driver and test it ?
I can't find no traces of the LX200stargo driver !

Thanks !

Sure. You can get the sources from Github.
github.com/sterne-jaeger/indi.git
Please checkout the branch named "stargo_work". In this branch you will find the sources under 3rdparty/indi-avalon.
You need to compile the sources as described in Readme.md in two steps:
- build libindi and install
- build 3rdparty (I would do it entirely) and install it.

Hope that helps
Wolfgang

Ok ! So tried at home, main feature are working well.
What's not working :
  • Motion control, lots of latency and not useable
  • Joystick not working

As I know a bit of C++ and looked at the source code, I may try to help improving this driver.
Let me know if you accept PR;

Again, thanks for this great work. Love to see Opensource minds are also astronomers :)

You might want to look at my pull request as well. I've ironed out a lot of the issues with the driver and I've been using it successfully for several sessions now.
I didn't do anything with the joystick control but the latency issue should be resolved. One outstanding issue is that sometimes it seems to revert to pulse guiding with pulses timed in the code. But this does not appear to work at all and causes calibrations in PHD2 to fail. It is resolved by clicking the Use Pulse Guiding button even if it already shows pulse guiding enabled. I need some spare time to test it more thoroughly to confirm if StarGo responds at all to these commands and if not that section of code should be deprecated.

Your version of the driver does not work at all for me. It maybe have to do with the firmware version of the mount. I got a Linear with a stargo 5.2.2 w/ firmware v5.2.3.
The mount wasn't able to sync home position. Indi claims it has empty response from the mount.
With the wolfgang one, I encounter some issues like : The dec axis never stops when goto.
