LaserShark Discussion / Re: serial communication

« on: February 25, 2016, 08:57:00 PM »

When you say "I see the strings", what are you referring to? Do you mean you have p= print command lines?

Have you tried piping the output to a file instead of lasershark_stdin.exe and reviewing/verifying the format there?

You say the galvos aren't moving. Is the laser not turning on/off too?

To keep discussions logically separated I'll respond to you in the other thread you created.

The 5v rail readings sound fine. I don't think I would bother with another computer. The lack of 12/-12v is concern. Try probing that again and if that still reads low perhaps it's time to consider sending it to me for further diagnostics (email me and we will set that up)

The first two set of pins should read 5V all the time (or something close). What you are measuring here is the 5v from your computer. If this value is too low (4.5v and below) then the analog power supply will stop functioning properly.

How do you have the LaserShark connected to your computer? Is it connected directly or through a hub? If a hub, is the hub powered? (The hub should be powered)


Try plugging the LaserShark directly into your computer (preferrably a port in the back) and test again. If it is still not operating properly, try probing the pins again. If the readings vary significantly you can try pressing a little harder. Over time an oxidation layer can form atop pads

It certainly sounds like the analog interface of the LaserShark has been damaged. This is based on  your statements that the program continues to run until you stop it and the fact the showcard still can drive the galvos.

Do you have a multimeter? First thing I would do is verify that the analog power is working (this is the black box on the board. If you look under the board you will see there is a set of two pins and a set of three pins.
Test 1: Probe the series of two pins and report the voltage. It should be about 5v.

Test 2: Probe the center of the three pins in series (gnd) and one of the adjacent external pins. Repeat for the other pin These should read -12 and 12v.

Ok, that is the proper way to pipe one command output into another.

Was I correct in assuming the program returned immediately when you run it (after outputting what you reported in the first post)? This should not happen, it should run until you stop it manually.

What happens if you just run lasershark_stdin_circlemaker.exe. Does it continuously stream a series of lines or does it end?

These messages indicate that you are successfully talking to the LaserShark and that the program successfully started, ran, and ended.

If it ended immediately, it is because no more input was available to be output. This makes me suspect you are not piping in the output of circlemaker into the lasershark_stdin app correctly.

Can you paste the command you are using to run this? Also, what platform are you on?

Apologies for the delay, had a few busy work days again.

Argh, the av conversion stuff always changes. You are receiving that warning because you need to install the package libavresample-dev. Even if you install this however openlase needs to be patched yet again for this to start working again. Yes, as you have seen KamalMostafa's has made some changes to allow it to work. I think those are sufficient but since this is a tangental problem lets just comment out that build step so the rest of OpenLase compiles. The qplayvid allows videos to be displayed on the laser projector by edge tracing if you wre curious.

To disable it, change to the tools/qplayvid directory and open the CMakeLists.txt file and change this line:
if(QT4_FOUND AND FFMPEG_FOUND AND SWSCALE_FOUND AND BUILD_TRACER)
to this:
if(FALSE AND QT4_FOUND AND FFMPEG_FOUND AND SWSCALE_FOUND AND BUILD_TRACER)




sudo apt-get install libavresample-dev

A laptop like that should be fine. Yea, you can try Mint however I'm not sure if that is going to help. Let me know what the results are and we can take it from there.

Hmm,

Those settings seem OK too. I do see that you have an xrun in jack. Ideally you should not have any. Are you consistently observing these? What are the specs of this laptop? Have you tried reducing the sample rate and increasing the frames/period value to see if this improve the situation?

Have you rebooted since first setting this up? It is important to make sure that you open qjackctl and click the start button BEFORE running anything else to ensure they run in that jack session vs another one.


If the above suggestions don't work, can you run the following?
file <path to example application>

Glad you got it working. Please be careful with your galvos as these games can strain them. The galvos should not sound strained when operating. If they do, this is likely to reduce the operational lifespan of the galvos units.

Did you pay for the game? You need to insert quarters to play. Press the 5 key (insert coint) before pressing the 1 key (start)

Hmm, I haven't seen this before. Immediately this makes me think there is a Jack configuration issue, or a problem in how OpenLase was configured or compiled.

Thanks for the screenshot. Based on this it looks like your Jack patchbay looks ok.

Your Jack patchbay looks ok. Can you take a screenshot of the jack "Setup..." window too? Specifically I'll be interested to see if you have the driver set to "dummy" or an actual audio interface.

macpod@computer ~/.xmame/roms $ tree

1 directory, 5 files

Try re-acquiring your rom files and installing them in your rom folder as above. Once you have done this run the tree command and paste the results here if it still does not work. Something isn't adding up. Either you have accidentally added a space to the names or the files are not actually in the right location.

I develop/test with Linux Mint. This is based off the Ubuntu codebase and your 14.04 64 bit should be fine.

To dive into this:
- Am I correct to assume you are running Ubuntu directly on the hardware vs through something like VirtualBox or VMWare Player?

-Can you run the lasershark_stdin app and circlemaker app successfully?

-Can you take a screenshot of your patchbay configuration inside of qjackctl (with all components expanded)?
