This fun application allows you to load any bitmap image (8bit or 24bit colour depth), and display it back to the user via a 2D array of LEDs.
The block diagram is well documented, and should be fairly easy to follow.
Please note that you are not tied down to a presubscribed LED colour set. When you run the application, you will be greeted with a dialog box, which allows you to select the foreground and background colours of the Matrix.
So you get the following types of effects...
Once your image is loaded, feel free to experiment with the “Intensity Threshold” and the “Matrix Resolution”. Increasing the Matrix Resolution increases the size of DotMatrix, and reduces the number of pixels represented by a single LED.
Do you want to finally get the recognition you deserve... and see your name in lights? All you need to do is open up windows paint and write your name. Save the image as a bitmap (.bmp). Feel free to use colours, but remember that this application just uses intensity to create the binary image that is displayed back to the user.
Open and run the DOT MATRIX (final).vi, and load your freshly saved bitmap.
LabVIEW 2009 or later.
One last note
To my American cousins, please note that I have opted for the correct spelling of the word “colour”
At the request of the community, I have also added a version of the code saved in LabVIEW 8.5 (DotMatrix 8-5.zip)
