That is:=20 display addresses 01, 03, 05, 07. I have my displays running on the=20 bench right now, so I'll give those upper bit addresses a try later=20 on today to see what happens. Worst comes to worst, I'll sacrifice one of my displays and break it=20 apart to see if there are actually LEDs installed at the decimal=20 point locations. I'll post my PIC assembler code on the list for others to use=20 sometime later today or this weekend. dwayne --=20 Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
