only lcd 12th pin is showing voltage level high and remaining data pins are showing low.
the pull up resistor(8 pins) connected to these data lines is showing low and pull up resistor 9th pin which is connected to vcc is high.
we used 3 pull up resistors
1.at port 1 used for 7 switches (here all the 9 pins of pull up resistor is showing high)
2.at port2 used for data pins of lcd(only 9thpin showing high remaining pins is showing low)
3.at port 0 used for control pins (here all the 9 pins of pull up resistor is showing high)
please any one help where is the problem
