Charlieplex Kit Marquee Code

[sparr]

Thanks! I haven\'t gotten to assemble my kits yet so I didn\'t get around to writing any code for this, but I\'m glad to see people successfully using it! I hope to have a pixel and bitmap library for it soon.

Wow! This is really cool and helpful for someone like me who really doesn\'t know how to program. One issues I\'m having is Z doesn\'t seem to work right. It comes across all garbled up.

Glad everyone digs it!

@ehisforadam I haven\'t tested this but I think the characterMap array might be one element too short so when rendering Z it\'s just reading from random memory. Try upping the size it to 59:

(Z in ASCII is 90, 90 - 32 = 58, which is just outside the range of the array)

@ehisforadam yep, that was it. I\'ve updated the code on GitHub

@dncinnes awesome! It works perfectly. Thanks.

Hi, thanks dmcinnes for your contribution!  I hope to try it out soon when I finish soldering my shield.

I'm confused about what it says on the wiki.

http://digistump.com/wiki/digispark/tutorials/led

Programming:   A basic demo sketch is included with the Digispark Arduino Addon package. We hope that Sparr or other members of the community will contribute a working library to make it easier to use.

Where?  I don't see any Charlieplex in the examples.  I can use the code linked to, but I think it would be nice if the wiki had some useful links for other newcomers to follow.  I just don't see where the standard example is supposed to be and I'm confused.

You can find the included example: File->Examples->Digispark->Charlieplex


The wiki is open for all to edit and contribute - so if you feel it is missing something please feel free to add it!


Thanks,
Erik

Cool!
