Curtain Style DMD capability

Post by Rajesh279 » Thu Jun 08, 2017 2:06 pm

Hello All,
I have tried scrolling from left to right using DMD library on Arduino. Its working fine.
I have few questions on the capabilities/features of DMD or DMD2 library for developing my new features:

1. Can DMD support Font size of 32X32 to display on 32(rows)X(any no. of columns)? How to generate those fonts?
2. I want features like
a) Curtain style text close and open from Left to right & right to left.
b) Scroll from top to bottom & bottom to top.
c) Display e.g. 4 digit static text on left side ( e.g. a city Bus no.) and remaining scrolling text( single or split marquee).
Can I develop these features using DMD/DMD2 library ? I mean, does DMD/DMD2 library supports this?
I want to develop on 32(rows) X 256 (columns), i.e. 2X8 DMD arrangement, is Arduino enough to support this or do I need to try on any ARM processor?

Any suggestion/help would be highly appreciated.

Thanks in advance.
