i attach 3 of these 5v max7219 8-digit red led display module 7 segment digital tube arduino mcu (see amazon http://www.amazon.co.uk/max7219-8-digit-display-segment-digital/dp/b00ihse6v6/ref=sr_1_2?ie=utf8&qid=1402251745&sr=8-2&keywords=max7219) mega 256. possible, , if how connected (i'm using pins 2, 3, 18, 19, 20, 21)? there library available use display both chars , digits (i want display 3 chars 2 digits point , 3 digits) on each module.

those displays don't give easy access dout pin can't daisy-chain displays.  need separate cs each can tie clk , din pins together.
