Re: Example LabVIEW Apps - Dashboard, CMUcam2 and Motors

We have a new version of both the Motor Sim Application and the CMUCam2 Application.

The motor sim application should be functionally the same, but for those of you who are interested in how it works, this new version will be a little easier to follow.

For the CMUCam2 application, there is a major new feature that allows you to use tracking line mode 2 (see the camera reference) which returns only statistics about each line instead of a bitmap of the tracked pixels. This allows you to get nearly 8 updates / second. Mode 1 (tracking bitmap) will run at just over 2 updates / second. Given that the target is a rectangle, it should be possible to get all the information available about the target in mode 2. This will hopefully prove useful in preparing the camera for use on the RC.

The update also fixes a possible problem with the frame grabbing function that would cause the frame to not be fully downloaded from the camera. This was most often evident when using a USB to RS232 converter as opposed to a standard serial port.

The updates are located at the NI FTP Site for now.

Good luck!
