I want to interface LCD module JHD 162A to atmega8515. I use CodeVisionAVR to compile c porgrams. It has built in functions for lcd control. but the help file says:

"These LCD Functions are intended for easy interfacing between C programs and alphanumeric LCD modules built with the Hitachi HD44780 chip or equivalent.
The LCD is connected to the AVR external data and address buses as an 8 bit peripheral.
This type of connection is used in the Kanda Systems STK200+ and STK300 development boards. For the LCD connection, please consult the documentation that came with your development board."

Hi, i have bought a HD44780 based LCD of 16x2characters with Blue backlight. And i have problem using it. Its not working basically. I have tried all ways of connectivity to a PC parallel port but to no avail. When i poweron the LCD it just displays the blocks of first row. And after that whichever control software i use it doesn't affect the LCD. Please help me in this as i am very much worried why i am not able to do it.

Thanx,
