Hi
I dont know how to post schematic
But i will try this way
p0 is connected via pull-up to Vcc
ULN2003 used

p0.0 --- ULN pin1 --- segment a
p0.1 --- ULN pin2 --- segment b
p0.2 --- ULN pin3 --- segment c
p0.3 --- ULN pin4 --- segment d
p0.4 --- ULN pin5 --- segment e
p0.5 --- ULN pin6 --- segment f
p0.6 --- ULN pin7 --- segment g

p2.0 --- cathode of display 1
p2.1 --- cathode of display 2
p2.2 --- cathode of display 3
p2.3 --- cathode of display 4
p2.4 --- cathode of display 5
p2.5 --- cathode of display 6
p2.6 --- cathode of display 7
p2.7 --- cathode of display 8

thus to display 0
I use mov p0,#0c0h
mov p2,#0feh
