I'm getting so frustrated with trying to do this.....I have been working with 'CrossRoads" as well to try and get mine working..
I have 4 MAX7219 and 4 8 x 8 matrices.....I can only get the first two matrices to light up totally (all 64 LEDs) on each but the other two blink when powered up and then nothing..
I have 1.0.1 and I don't understand why some of these posts say use "LedControl.h" When I try that it just says error compiling....
I am using a Mega2560 and using SPI library...
I have 51 = MOSI
52 = CLK (SCK)
53 = (1st Chip Load)
49 = (2nd chip Load)
48 = (3rd chip Load)
47 = (4th chip Load)
My code is way too long to post here due to the mega also controlling other circuits but What am I doing wrong...
I have the (MOSI) DataIn pins all in parallel (Im not using Data Out (Pin 24 of Max7219) to cascade)
I have SCK all in Parallel
and then the SS (Loads) are all individually connected to each Pin out assigned above.....
I have 10 Resistors for Iset
Trying to get them to scroll..........
Any help would be appreciated...
