Three dot-matrix displays and only two MAX7219
Hello,
I have small problem. I have three dot-matrix displays (display datasheet: http://pdf1.alldatasheet.com/datasheet-pdf/view/101069/KINGBRIGHT/TA12-11EWA.html) and only two MAX7219. One MAX7219 is proposed for 8 cathode multiplex. There is no problem. But I have no idea, how to wire matrix-LED anodes, because part of anodes on the middle matrix display woud be both on the first and on the second MAX7219.
Please help me, how to wire it correctly.
Thank you very much
