Can't find CMUCam2 demo.llb

[railerobotics]

Now that we have the application and have it on the computer in lab view, we cannot get it to run. I click the little arrow and a little error window pops up and says something like that we need to check our serial port or see if the camara has power. The serial port is fine, we spent hours checking it. And the camara has power. WHATS WRONG??? Please help us.

Could be a number of things.

1. Make sure the backup battery is FULLY CHARGED.
2. Make sure you've installed the latest version of the NI-VISA software in your computer.
3. Make sure you've configured your serial port to the correct speed via Measurement and Automation Explorer.
4. Make sure the serial port specified in the application is the correct serial port the serial cable is plugged into.
5. Make sure the backup battery is FULLY CHARGED.
6. Make sure you've read the documentation provided with the Camera App.
7. Make sure your serial cable is good.
8. Make sure the camera is correctly set up and everything is plugged in snugly (especially the lens daughterboard).

And above all, make sure your backup battery is fully charged.

thanks, it now works. The file we were missing mi-visa was in the documention of the frc camara.

You said, "If you use easyC for FRC the camera values for the target are preloaded in the software. If you upload Tutorial #7 to your robot it should folow the target." Where is "Tutorial #7"?

We have another porblem. We can now get CMUCam2 demo.llb to run, but when we try to capture a frame we get an error. But our serial cabel is connected and the camara has power. So why do we get this!? help

There was a bug in the get picture.vi that caused problems grabbing frames, especially if you are using a USB to Serial converter. There is an update posted here.

Good luck!

That has been already downloaded. But now, we can start the program without any errors then when clicking the "grab frame" button it downloads all the way and no picture appears on the screen, and it restarts itself over and over. What's wrong?

[railerobotics]

After downloading the code to the robot controller and the terminal window pops up, nothing happens in it. Why is this?

If you downloaded the code a few days ago, the code was messed-up for a while.

We've tried that and it still didn't work.

Rebuild the code with debugging messages on (see camera.h) and post the output (if any) here.

-Kevin

[railerobotics]

Here is the debug.

Camera: Initialized abnormally with code 131
Camera: Initialization state = 1
Camera: No EEPROM configuration data found; using default parameters
Camera: Initialization state = 2
Camera: Initializatoin state =3

This continues over and over again.

This may have been said already... but it never hurts to say it again.

My team has wasted 4 weeks on the same problem. The code will not load correctly and execute if the robot radio OI (what runs your joystick) is not connected and functioning. The out-of-the box code should always work as long as you have not altered it in any way and have it wired according to the instructions. (PWM 1 & 2 for Pan/Tilt, TTL chip connected to controller, and power pwm cable) To make sure your OI is working, make sure the light next to RADIO on the controller is green, and not red or orange.

I really hope this helps... this camera gets really frustrating. Keep working hard guys, see ya at competition.

Does it look like the button is sticking down? There is a "Mechanical Action" option for the button that will change the way it acts. if it is stickingm you will need to change the mechanical action. If you haven't change that, though, it should be ok by default.

Is it possible that youare double clicking the button?

Are you sure you downloaded the latest version there? The old version is still there along with the updated one. Look at the dates in the file names.

Are you still seeing the behavior? Can you give any more information about what is happening?

We have fixed the problems with labview, we just over wrote our Cmucam2 demo files. The problems we are have know is that when we download the camera code through ifi loader the terminal window is blanck. It is suppose to say searching and then give values.
