p.s. what i am hoping is that these cheap, single-board computers will spark new interest in INDI...

It buys me access to the self-guider . And hopefully would provide me a way around using $500+ software to guide and image.

I wish I could use the Http server with my St-10.

i'll check it out. just browsing thru the files you've uploaded, it seems like mount control is done thru CdC with the INDI interface, is that correct?




Yes. A mount is controlled via INDI/CdC in the background.

Can it control an SBIG camera?




No because SBIG doesn't release libraries for Arm Linux. QSI can be controlled using QSI open library and GoQat.

Can anyone confirm Orion SSAG is working with lin_guider? I am trying to implement on my RPi, but can't seem to get lin_guider to recognize the SSAG.

It appears to be recognized in lsusb:

Code:
Bus 001 Device 005: ID 1856:0011



However, I get the following error messages when starting lin_guider:
Code:

[1370797037:231] ERROR: Unable to find config file '/home/pi/.config/GM_software/devconf3.conf'
using defaults
[1370797037:239] lusb::initialize(): Success
[1370797037:249] ERROR: qhy5_core_shared::open_device(): Could not open the QHY5 device
[1370797037:252] ERROR: Error opening device: qhy5: code=1



Just noticed the "config" file error now, so will do some more research, but what settings are you using in lin_guider to get the SSAG working?

Cheers,
Corey

ssag and qhy5 have different vid/pid. I dont have notes handy offhand, but, you probably just need to make it search for a different vid/pid.

Thanks... That had occurred to me as well, but I'm not sure how to do that... Any ideas where to start?

No dice in getting the SSAG working under Linux. I found one thread on another forum suggesting that you could reflash the EEPROM to make it mimic a QHY5, but that requires (1) Win XP and (2) willingness to mess with the hardware, neither of which are in the cards for me.

Am giving up on this for tonight and will be guiding with PHD on my MacBook for now... Will post an update if I can get it working. Still open to any advice from others who might have got this to work.

Cheers,
Corey

The SSAG works out of the box for me. Please download firmware from

https://sourceforge.net/projects/cccd/files/firmware/

Then,

sudo dpkg -i firmware-ccd_1.0_all.deb

Should have let you know that I tried that on the weekend with no luck.

All that being said, I fired things up tonight and everything worked on the first attempt. Although I tried every iteration I could think of earlier (or at least I think I did), it is more or less working tonight. I say more or less because I'm getting the occasional read error message and the Pi seems to lock up after a few minutes. Not sure if the two are connected...

For what it's worth, I made a point of:

(1) Ensuring all peripherals were connected to a powered USB hub, and
(2) Ensuring the SSAG was plugged in before I booted the Pi.

The USB cable has always been a bit loose fitting on my SSAG and I also made triple-sure I had a good connection. (I normally tape the cable in place to prevent it coming loose when it's on the telescope.)

Beyond those things, I can't say I have any sage advice... Just glad it's working so I can move on to the next trouble-shooting activity!

Cheers and thanks to all for the help,
Corey

Please make use that your powered usb hub is one of those in the working list.

I'm at the same point smartc was as of this post. Using a supported, powered USB hub, installed the ccd firmware package. Any other suggestions?

Please use the command "dmesg" and post here. The camera should be assigned as QHY5 in dmesg logs.

Thanks for the response. I'm away from my RPi, but the SSAG wasn't recognized as QHY5 in lsusb, just showed up as
"Bus 001 Device 005: ID 1856:0011"

As I played with it, I modified the qhy5 rules from lin_guider 26, changed any vid/pid that said 1618 to 1856 and 0901 to 0011. Then re-ran qhy5_lg_install.sh. After that the device shows up as QHY VOTI in dmesg, QHY5 in /dev and appears to be working nicely. However, I suspect this isn't the best approach.

If you had a clean install of raspbian and installed "firmware-ccd_1.0_all.deb", your SSAG would be detected properly?

Your approach is ok. The qhy5 and ssag are indeed the same hardware, but, programmed with different vid/pid numbers. If you want your system to correctly recognize either variant, then adding more rules for the alternate id's would be the approach you need.

I finally managed to get lin_guider up and going but it seems to be over agressive in its adjustments - any thoughts on proper settings? I am used to PHd, but linguider seems to run better on the pi. I have oc'd the pi, wondering if its affecting timing, etc.

Hi radarboy,
I am experiencing the same over-aggressiveness with lin_guider on my non-oc'd Pi.
Did you progress in any way on this issue?
Thanks.
Piero

My guess is you should lower the proportional gain in the guider settings menu.

I'm curious if you've tried this with a NexImage or Philips spc900nc webcam. If so would a gpusb no longer be needed as I hope the pi or mk808 will replace that module?
I just learned about HitecAstro which prompted to look further into this.

Philips spc900nc is supported by Linguider and the new version of Linguider (not released yet) also supports the GPUSB adapter. You will need the GPUSB or similar adapter if you use a camera with no autoguiding port.
