ok, but how do i connect it all to the max7219? i haven't found a tutorial or anything on it..
Nick, you need to put "<a name =" links into your pages so you can reference individual sub-topics.
I did that a while back for each reply on my pages. If you RH-click on "Reply #1" for example (at the start of a reply) and "Copy Link Location" you get a usable link with an anchor
is there a specific diagram for 3 digit 11 pin?
you have 8 pins on one side and 4 on the other where as i have 5 on one side and 6 on the other.. to me there is no comparison
MAX7219 expects to source current into 8 anodes and and sink current from 1 digit.You have to add extra hardware to use common anode, see this application note:http://www.maximintegrated.com/app-notes/index.mvp/id/1196
It only matters anyway if you wish to use the character generator which is limited to digits 1 to 9 and the characters "-EHLP" - if you wish to define other characters, you cannot use the internal character generator anyway.
