baum, thank you so much!
So, you mean if I use the given codes to the 8x8 led matrix with backpack from sparkfun, it won't work right?
The point is that I just started to know about arduino and processing and my plan was that to see how it works after I finish my own project with looking at the website.
But I don't really know how to do with SPI and
if I take it off, everything such as given codes and connecting wire stuffs will be changed, then it will be too hard for me to do the project...
If i just have 8x8 led matrix without PCB, can you help me how to code for both arduino and processing ( I want to use both, not just arduino) and how to connect the wires to the breadboard?
I just want to start asap.. lol
it's been like a week to think about this....
