Greetings members, first post here.
Recently i bought the arduino uno and duemilanove and i am having great fun with the tutorials so far. The last one i did was the Serial to Parallel Shifting-Out with a 74HC595. Since i scavenged an led board from an emergency light i decided to make this work in a similar fashion, just to display text and not to blink. The led board is 3x13 so i got five of the 74hc595, i got them connected and they work fine. For the part of the coding i have a problem with understanding how to do this best. The example Dual Defined Arrays uses two separate arrays, one for the green led's and one for the red led's. I want to use 2d array to control the led's. Can i do this? As i said the led board is 3x13 and the connections are set left to right by rows so the first ic has 8 led in the first row, the second ic in the first and second row, the third in the second row and so forth... My idea was to control them all at once and not just sending 8 bits like in the example. Can you point to some other examples or show some code of how to do this?
