Some things to note about this program:
- If you don’t have Processing on your computer, download it here.
- The editing interface is easy point-and-click. Try it out to see how it works.
- You can individually pick different delay times per frame, as low as 20 ms, or give every frame the same duration.
- The frame data is stored in Arduino program memory, so you’re only limited by the flash memory in terms of frame number– over 250 frames fit on an ATmega328P.
- The output file is located in the PeggyDraw2 sketch directory, inside a directory named
“PeggyProgram”“data.” The file is called “PeggyProgram.pde.”
- You can both save a file and later reload it for editing.
- The formats used in PeggyDraw 2 should be easily adaptable to write sequences for other types of LED grids, even of different aspect ratio and control software.
And, special thanks to Matt Mets, http://cibomahto.com for assistance with Processing.
Update, 3/19/2011: We’ve posted a new version, PeggyDraw 2 v. 1.1, available at the same location. Note that the output file is now stored in the “data” directory, not a separate “PeggyProgram” directory.
