My basic "end-result" is that I can give my program a string, and my 8 by 8 LED matrix would output it until I change the string.
I already have the code to display a sprite from bytes (similar to the one in the bitmath tutorial), and I also have code to read an array of bytes and scroll them (for example the array shown would scroll "HELLO"
B11111110, B00010000, B00010000, B00010000, B11111110, B00000000, B11111110, B10010010, B10010010, B10010010, B10010010, B00000000, B11111110, B10000000, B10000000, B10000000, B00000000, B11111110, B10000000, B10000000, B10000000, B00000000, B01111100, B10000010, B10000010, B10000010, B01111100, B00000000
My problem is that I have absolutely no idea how to convert the string into an array of this form, and http://dotmatrixdesign.tumblr.com/ gave me the idea to make a char library but I didn't get very far.
Any help would be appreciated, even if it means my current pieces of code are wasted.
