need help with graphics lcd

[hermione]

can anybody plz help me .. i want to display values of voltage of variable resistor which is connected to adc 0809 on a graphics lcd..
graphics lcd - 240x128 with t6963c controller
microcontroller used - atmel 89c51
i am programming in assembly language..need some help with the programming

i think you should to be more specific in defining your project.
What is the problem? ADC? or LCD?i would like to suggest you C Programming Language for complex project.It's quite hard to manage assembly language for large project if you aren't used to it.
