Ximea camera returning error as data #131

Closed juliomateoslangerak closed 4 years ago

juliomateoslangerak commented 4 years ago

I'm having issues getting data from the ximea camera on the new merged version.

juliomateoslangerak commented 4 years ago

Server side this is the traceback:

carandraug commented 4 years ago

There's two different issues. The first issue is that the default is not software trigger. That's easy to solve. The second issue comes from 9fe103058e54afdee28f9808655657dff495e916 but @NickHallONBI should be able to comment (the original code only checked two conditions).

carandraug commented 4 years ago

For starters, can you try my issue-131-ximea branch?

carandraug commented 4 years ago

Oh, when you call set_trigger_source, it expects a value of 1 (edge rising) or 0 (software). Can you try:

camera.set_trigger_source(0)

edit: ignore. This is wrong. Ignore me. We have both set_trigger_source and set_trigger_type and got confused.

NickHallPhysics commented 4 years ago

Right, so after a bit of digging, it seems that we never actually call the set_trigger_source/type in any of our other softwares (microAO, cockpit, BeamDelta, etc). It's quite possible that these methods never worked and because we were always happy with the defaults (software or hardware triggering) it just never came up.

carandraug commented 4 years ago

Do not know if this has something to do with it but camera.get_is_enabled() returns nothing after changing trigger mode unless it is enabled again.

I think this is a separate issue and general to all cameras. Only CameraDevice.enable sets the attribute of CameraDevice.enabled to True and it's set to False in __init__ so until you call enable, CameraDevice.enabled is None.

juliomateoslangerak commented 4 years ago

The error seems to be caused by an uninitialized camera. Is actually 'initialize' ever called? I'm not sure cause I cannot see it in the logs. At least not at the right moment.

carandraug commented 4 years ago

Is actually 'initialize' ever called?

Yes. It is called by the deviceserver. A device is only served after initialize succeeds.

Ignoring the set/get trigger source/type, does my issue-131-ximea branch lets you enable and then trigger and wait for an image?

carandraug commented 4 years ago

Me and Nick explored this and found that when trigger source is set to edge rising, the camera still handles software triggers. This explains why the default trigger mode was edge rising, and trigger from cockpit still worked even though we never actually called any of the functions that changed the trigger source/type.

Anyway, we believe the actual issue here should have been fixed with https://github.com/MicronOxford/microscope/commit/973863886793e58314cb0e6e55ca41bc3f9109b0 we just checked on the actual camera. So closing this issue (please reopen if you still have issues).

juliomateoslangerak commented 4 years ago

I installed from scratch your commit and I still getting the errors. I paste output bellow.

I still think it is that the camera does not get initialized. A call to initialize should print 'Initializing.' in the log and I cannot find it.

juliomateoslangerak commented 4 years ago

funny. If I call initialize at the end of the init method, Initializing is printed twice. And things do not get better. Maybe camera firmware of api differences? mine is: Name: MQ042MG-CM Sensor: Mono Type: USB3.0 Serial number: 38983550 User ID: API version: 4.18.00.04 Driver version: 2.00.00.08 MCU1 version: 4.00.00.00 MCU2 version: 4.00.00.00 FPGA1 version: 2.49.00.00

juliomateoslangerak commented 4 years ago

I cannot reopen the issue BTW

carandraug commented 4 years ago

I managed to reproduce your new issue. There's a few things going on:

  1. When you call XimeaCamera.enable, it first starts the fetch thread and then starts the acquisition which means that the fetch thread must handle not having the acquisition started yet. That problem should go away if on the ximea module line 117, you do self._acquiring = True after self._handle.start_acquisition()

  2. If start_acquisition() fails, the camera is left as disabled but it's also set to acquiring and the fetch thread is not stopped. The end result is that each millisecond the fetch thread fails with error 45 ("Acquisition is stopped. It needs to be started to perform operation") when it tries to fetch an image. And indeed acquisition was actually never started successfully. There's probably some other error in the logs, from when start_acquisition() failed, but it will be under thousands of tracebacks for error 45. If youu fix the point 1 above as I suggest above, it should be clear what error comes out of start_acquisition() (on my case is error 13).

I would also recommend you try to test this without deviceserver, so you also get the xiAPI log messages. Like so:

>>> import microscope.cameras.ximea
>>> import logging
>>> import sys
>>> logging.getLogger().addHandler(logging.StreamHandler(sys.stderr))
>>> logging.getLogger().setLevel(logging.DEBUG)
>>> c = microscope.cameras.ximea.XimeaCamera()
>>> c.initialize()
xiAPI: ---- xiOpenDevice API:V4.19.11.00 started ----
[... Loads of xiAPI log messages very useful ...]
Initializing.
xiAPI: Sensor SetExposure freq=48MHz exp=28us regexp=x2
>>> c.enable()
Enabling ...
Preparing for acquisition.
[... Loads of xiAPI log messages very useful ...]
Error in _on_enable:
[... traceback information ...]
ximea.xiapi.Xi_error: ERROR 13: Attach buffers error

I still think it is that the camera does not get initialized. A call to initialize should print 'Initializing.' in the log and I cannot find it.

Are you looking at the stderr or the at log files? The individual device log files are only created after initialization so it won't appear there. They should appear on stderr though.

juliomateoslangerak commented 4 years ago

So I applied your change and that seems to fix the problem. As you say the camera seems to respond to software triggers even when set in HW trigger mode. However if I change to software trigger mode, something must go wrong during the 'Disabling_acquisition' and I get the error 45 again. I must disable and enable my self to get things to work again after setting the software trigger. Here are the logs

I tried as you mention without deviceserver but I don't get the ximeaAPI messages...

So for the initialization, indeed I must have been looking at the log file. Though normally I follow the trace in the terminal... 'Initializing.' is there

Can you pop by #python-microscope on irc.freenode for a debug session? I think we would benefit for a bit less async debug session.

How do I do that? I went to the webchat but could not find #python-microscope

You can use yuour own IRC client if you have one. Otherwise, https://webchat.freenode.net/ should work. I just tried on another computer and worked fine (wait a few seconds for the connection). Make sure, there's no typo on #python-microscope (the # is part of channel name).

IRC client is not working. Probably blocked by the IT the webchat I'm connected as Julio55 but I cannot find the channel

I spoke with @juliomateoslangerak over IRC. The original problem on this issue was fixed by changing the order of calling start_acquisition() and setting _acquiring but in the mean time 657948abd8eb0c0834efb1a1f8 also fixed the issue and applies to all cameras.

The other general issue of set/get trigger type/source not working properly is now also fixed by making use of the TriggerTargetMixIn with 6c1974ab57f5b608614d.

Closing as fixed.
