DMD Pattern Code Generator

Post by xeri » Sun Nov 22, 2015 11:27 am

For what it's worth, attached is a rough-and-ready code generator built with Excel and a VB Macro.

You draw the item that you want on the template worksheet (copy and paste the red ".") and then generate the pixel code (basically a bunch of dmd.setpixel() lines) via the Code worksheet.

It assumes use of the DMD2 code library but the VB is pretty basic and easy to follow/modify. The "mode" in the function is the DMDGraphicsMode (GRAPHICS_ON, GRAPHICS_OFF, etc) used to turn the pattern on, off, etc.

Not terribly efficient but hey, it works! I found it useful for mucking around and prototyping.

Hopefully someone else finds it helpful!
