I have been playing around with my 8x8 LED matrix and for some reason when I use Espruino my 4th column (from the left) does not work, I know it is not a hardware issue because if I use the matrix with Arduino it works just fine.
SPI1.setup({mosi:D14, sck:D13});
var disp = require("MAX7219").connect(SPI1,D15);
disp.intensity(0);
var arr = [255,255,255,255,255,255,255,255];
disp.raw(arr);
Here is the code I use to test the display, also I'm not sure if the MAX7219 module is the best to use?
