Ok,thanks.
Now i am trying to read data from ATMEGA8L-8PU when i tried first message is trouble pin contact of 8,9,11,12,13,15,16,17,18,19........
yes or cancel,then when i yes it it shows
from
0: to 1ff0:ff
and from 2000: to 21f0:it shows f7
please confirm me is it my data which stored in this controller.
Because we have two similar 7 segment display one is ok but when we try other one it does not show even 00 of 7 segment display.
