hi i design a device which monitor the level of a huge tank with avr atmega8535 and show a historical trend for this level but i need now to make a graph for this level values can any one help me how to use the graphical lcd 12864 thanks

It took me less than a minute to find the data sheet for this display using Google. It appears all the data to do this is in the data sheet. Isn't that what you're getting paid to do? Zack

Hello,
I have some avr gcc code for 12864 graphics lcd. In general there
are two files: glcd.h & glcd.c.
I hope that it can help to You.
