PHD2 on the Raspberry Pi2

[Patrick Chevalley]

Hi,

PHD2 is working well on the Raspberry Pi2 running Linux, so I add the ARMHF build to the Launchpad ppa.
It is very easy to install, see  https://launchpad.net/~pch/+archive/ubuntu/phd2

Also the ARM ZWO driver is now available and I add it to PHD2 yesterday. This make the ARM Linux version functionally equivalent to the x64 version but this is untested for now as I not own a ZWO camera. I am interested if someone can test this configuration.

I make a few test with my Pi2 running Ubuntu Mate 15.04, INDI drivers and remote VNC display.
The program run fine and is very reactive. All my potential guide camera (Meade DSI, DMK-21, Atik 314) worked without problem.

Thanks Patrick, great stuff!

Hi Patrick,
You make the life much easier. I have installed the phd2 but there is no driver for my QHY5L II. How can I install the driver for it?
Again, Thank you for your effort!

[Andy Galasso]

Sampson, I am currently working with the developer at QHY to update our drivers in PHD2.  I will see if they can provide an ARM version of their SDK for us.  It may take some time though since things are moving very slowly.

[Patrick Chevalley]

Sampson,
for now you can use the INDI driver for the QHY, it is available for ARM.
- add the following ppa: https://launchpad.net/~mutlaqja/+archive/ubuntu/ppa
- install (apt-get) indi-bin and indi-qhy
- start the indiserver in command line: indiserver indi_qhy_ccd
- look at the INDI forum if you have difficulties to run the indiserver: http://www.indilib.org/forum.html
- in PHD2 select "INDI Camera" then click the "Camera setup" button to select the QHY.

Hi,
I have done some initial work on adding qhy support to Linux version. You can find the code here
https://github.com/trlsmax/Open-PHD2

And you can find qhy SDK here
https://github.com/qhyccd-lzr/QHYCCD_Linux

But I have not test it yet,it may not work correctly.

Hi Max,

Why not contribute directly to the official project? We don't bite.  :)

We just moved from google code to github.

https://github.com/OpenPHDGuiding/phd2

I have been working with lzr to get his most recent SDK integrated into PHD2--Windows, OSX, and Linux.  Our work probably overlaps, so it would be nice to consolidate!

Andy

[max chen]

Hi Andy,

The reason I didn't do that because I'd talk with lzr and he said there will be official support by QHY

and I'd better not commit my code directly to the project.

But I'd wait months and for now PHD has migrate to github, so, I'm not sure if I should make a pull request.

As you said, maybe there will be overlaps or conflict with our code.

Should I wait for your code or just make a pull request ?

Thanks, Max.  Let's try to consolidate our work.  I made a fork https://github.com/agalasso/phd2_qhy with the qhy SDK changes (maybe a branch would have been better?).  I've been testing on windows, but it should be very close to working on OSX and Linux (probably just some cmake changes required).

I'll try to take a look at what you have done in your repo.  It may be a little tricky because I will not have any baseline to compare to.

Andy

[Thomas Landmann]

Very nice... I just fired this up on my Pi2 and I'll test it out as soon as the weather cooperates!

[max chen]

Hi Andy,

I just check your qhy fork and it's way better and cleaner than mine.

I will test it on Linux.

Max, thanks for looking at it. I think it still needs some cmake changes to link with the qhy library on Linux and OSX.

Andy

[max chen]

Hi Andy,

I modify some code to make phd2 compiled and link on linux. Code is here in branch qhy_linux
http://github.com/trlsmax/phd2_qhy

But qhylibs in directory cameras/qhyccdlibs is old and the latest version is here without static libs
https://github.com/qhyccd-lzr/QHYCCD_Linux

For now, it need to install those libs first to make phd2 compile and link , maybe I should contact lzr
to ask for a static version of libs

I will make a pull request when the code is ready.

Regards
Max

Thanks Max.  I'm not sure how we can figure out what the latest version of the qhy libs is. I got the SDK including the static libs directly from lzr on 6/24. It sure would be nice if we had a single source for the latest libs.

Hi Max,

Thank you so much for your effort. I could compile the phd2 with the qhy5l II M INDI driver. I will test it if the weather was fine.

Hi Patrick,

I have tried to install them but there was error. It reported that something wrong with my qhy ccd driver for Lin guider and could not overwrite the ccd driver. I have to remove package of qhy ccd driver for Lin guider before installing indi-bin and indi-qhy. Finally, I compiled the phd2 and the qhy driver given by Max Chen.

Regards,

Sampson

BTW, you are sure to make the life much easier for installing the phd2.

Hello. 

First I would like to thank you for your huge work with OpenPHD.

Then now the time has passed since your last messages and I would like to know if we can easily use the QHY5L-IIc camera with phd2 on linux ? Indeed, I have some trouble by using indi so I would be interested if the drivers was included in phd like Andi Galsso did suggested in his post.

 

Thanks again.

 

Best regards. 

[max chen]

Hello,
On linux, PHD2 and INDI use the same libqhy. So, if your camera can't be recognised by INDI, I don't think it will work with PHD2.
And QHY haven't update the sdk for a long time, even people asking on their forums got no responses.
I suggest use lin-guider instead , or someone port drivers from lin-guider to PHD2.

Regards
Max

Ok, thanks. But that is strange because it seems that some people are using these cameras on indi.

For now I use lin_guider but PHD2 seems to be better. Then lin_guider code comes from libqhy too :

"Device access code is based on original QHY code from https://github.com/qhyccd-lzr"

Moreover, I tried to compile PHD2 and I have an error: 

CMakeFiles/phd2.dir/indi_gui.cpp.o: In function `IndiGui::newMessage(INDI::BaseDevice*, int)':

indi_gui.cpp:(.text+0xaf0): undefined reference to `INDI::BaseDevice::messageQueue[abi:cxx11](int)'

Thanks for your help.

Hmm, that's a linker error. What INDI library version do you have there ?

[Cyril Richard]

I have the version available in debian testing repositories :

INDI Library: 1.0.0

Code $Revision: 726523 $. Protocol 1.7.

Can you try with the latest INDI (v1.2.0), following
http://indilib.org/support/tutorials/139-indi-library-on-raspberry-pi.html
http://indilib.org/download/raspberry-pi.html

[Cyril Richard]

Ok. I'll let you know.

[Cyril Richard]

OH, I am sorry but I should have said that I'm not on Rasberry.

But I will test the 1.2.0 version of INDI.

You can try the following:
edit phd.h
on line 67, replace
#include <math.h>
by
#include <cmath>
