Hello,

Thank You so much for you reply.

Project title: Developement of Graphical library for Easy Avr Board. i.e draw lines and shapes on the screen.
I need to write a Source Code using Embedded C.
For this project, Iam using atmega16 controller and LG12864b lcd display. Using AVR Studio Software for compiling. I have attached all the documents which is related to my project.

Note: I have a program with me but iam not understanding where did that program go wrong. iam not getting the required output while executing this program. I want some one to rectify the error underlying in this. Please find an attachment of the program(glcd.rar) above.

Thanking you

No required output means ru able to get some kind of output on the screen or the lcd itself is not ON?
If the grahical lcd is not ON, check your pin connections and especially contrast pin.
Is ur VEE pin negative in voltage?

If ur confident about above check the LCD intialization
After setting all the pins as output apply the reset signal to the lcd and then apply other signals
apply sufficeint delay between each intialization of pins
