I'm a new arduino user, working my way through the advice and tutorials on the arduino/wiring sites. Using Arduino 12 on a Mac, a Duemilanove, and an 8x8 LED matrix with a Maxim 7221/19 chip...
I have successfully run simple sketches
'wave'sprite, in the LED matrix reference
Seb DeeLisle's 'particles' - brilliant, but complex maths!
LedControl library examples
I have spent several days now looking for projects mentioned in this
forum, or through 'google', about scrolling images using arduino with
maxim 7221/19 and 8x8 matrix. I do not seem to have found what I need, but
perhaps it is there and I just don't recognize it?
I wish to be able to scroll, in x and y axes, around a 'picture' which is
a lot bigger (say 25 x 25?) than the 8x8 LED matrix. (Making a large 'sprite' and moving it around seemed like an elegant way of achieving this. However if the sprite size is limited to 8x8 I'll need to think again.)
I am hoping someone can explain the 'building blocks' required to move an image around on screen, which functions or libraries might help me in this, or even some (simple) code I might 'deconstruct'...
With this information I can, perhaps, work my way in small steps towards my goal.
Thanks.
