PiLED

NT API Documentation

When main.py is running, it will read 3 NetworkTable keys for commands. (They are in PiLED/matrix and PiLED/string respectively)

• type is a string that determines the type of media to display. The acceptable values are image, video, and video-one for one-shot videos
• file is a string that determines the file to read. For image mode, it is the name of the file to display. In video and video-one mode, it is the name of the folder the images are stored in.
• trigger is a number that, when changed, will trigger an update of the screen, determined by the above values. When it receives a command, it will write a boolean to result. True if it worked, false if it didn't.

Video Format

video and video-one mode expects the name of the folder to play. In the folder should be a file called video. It needs four lines with configuration information:

basename {basename}
fileext {ext}
frames {frames}
fps {fps}

Example

• {basename} is replaced with the base name of the file (if the images are imageXXXX.png, basename will be image).
• {ext} is the file extension. If the images are .png format, {ext} would be png.
• {frames} is the number of frames in the animation.
• {fps} is the framerate to run the animation at.

Of Note: The code expects the images to be formatted {basename}XXXX.{ext}. Therefore there is a maximum of 10,000 frames per video (5:33.0 at 30fps) which should be more than enough.
