I am new to INDI and am setting up my system for the first time. I have a SBIG ST10 with CFW8 filter wheel which I understand is supported, however I also have an 8 position Xagyl filter wheel that I would like to use (as it would let me have both LRBG filters as well as narrowband all loaded at the same time).

Is it currently possible to get the Xagyl filter wheel working under INDI ?

First question: Is your Xagyl wheel is identified correctly within Linux when you plugin it on your USB port? could be check easy with 'dmesg' command on linux terminal.
Anyway, I've attached to this thread the user manual I've found on Xagylastro site of this wheel for V3.x. From the page 17 we could find the procol for (all ?) commands. Maybe someone could read it and say if another existing Indi driver already use the same protocol.

- Anybody knows it?

Otherwise it shouldn't be to much difficult to write the driver for it as this is a native text communication protocol, as far as I see in the document.
Best regards

Can you connect to it via minicom? If you can, type in i8 and let me know if you get anything, it's suppose to return the maximum number of slots.

Hi forum..

I have some code I modified to work with Xagyl wheel with 5 filters but I think that making just a couple of changes will work with any number of filters.
The code is a bit messy but works and Jasem can propably make it clean.



ps. Don't laugh too much, I'm not a coder

Thanks, I already began writing the driver yesterday, but wanted to get confirmation that serial communication works. Do you have XAGYL wheel as well?

EDIT: Thanks, looking at your code it looks like that newline is part of the command and response. I wanted to know that.

I have a Xagyl wheel the first version with serial interface.
As I remember the newline character is also returned so that is correct.
My filterwheel broke for some unknown reason for about 6 months ago so I wrote code for a Arduino and connected to Xagyl wheel because I couldn't get a replacement pcb from them but propably will buy a 8-slot wheel later on.
There is one thing I thought about, the slot position finetune should be made using Windows using the software that comes with the wheel because I never found out how to do that in the driver, you propably see that in my code.

Thanks Jasem to make a driver of my mess..

What's the range of the calibration offset? It's say PX Offset XX? Is it 0 to 99? Is there negative to distinguish clockwise from counter clockwise? Documentation is unclear on this.

I'm not really shure but my notes say the values should be from -99 to 99 for PX Offset, maybe rmuhlack could doublecheck that by sending the command I6 to the wheel ?? maybe the values is visible in the Windows app too ?? ( I just used it once to make the first calibration)

Ok, alpha driver complete and ready for testing. Please turn on DEBUG and LOGGING _before_ you connect, then specify serial port in Options, then connect and proceed normally. It should be available in the PPA tomorrow.

I'm impressed!!
Thank you!!

Just to let you know that I have a Xagyl wheel and have successfully written a driver. I found the protocol very straightforward to support and have had no problems with the driver.

I'd share the code; although its ugly and I am sure you will produce a driver that is far better integrated with INDI than mine.

It would be great if you can test the INDI driver which should be in the PPA now.
