Cascading Max7219

Great! Did you figure out how to sort the ordering?

Something like this should do it...

SPI2.setup({mosi:B15, sck:B13});
var disp = require("MAX7219").connect(SPI2, B14, 8);
var gdisp = Graphics.createArrayBuffer(64, 8, 1);
var g = Graphics.createArrayBuffer(32, 16, 1, {msb:true});
g.flip = function() {
  var im = new Uint8Array(35);
  im.set([32,8,1]);
  im.set(new Uint8Array(g.buffer), 3);
  gdisp.clear();
  gdisp.drawImage(im,0,0);
  im.set(new Uint8Array(g.buffer,32), 3);
  gdisp.drawImage(im,32,0);
  disp.raw(gdisp.buffer);
};
g.drawLine(0,0,32,16);
g.flip();
