The table below shows the wiring between the LCD, ATmega32, and the 14 pin header that that connects the LCD to the microcontroller.

I use the standard 4 bit interface strategy to drive the LCD.

 

LCD Pins ->   | 11 | 12 | 13 | 14 | 4  | 5  | 6 |
LCD Signals-> |DB4 |DB5 |DB6 |DB7 | RS |R/W | E |
ATmega32 ->   |PC0 |PC1 |PC2 |PC3 |PC4 |PC5 |PC6|
ATmega Pins-> |22  | 23 | 24 | 25 | 26 | 27 | 28|
14 Pin hdr -> |12  | 11 | 14 | 13 | 3  | 6  | 5 |

Pin 1 -> VCC (+5VDC)
Pin 2 -> GND
Pin 4 -> Wiper of 10K potentiometer between VCC& GND.
Pin 7,8,9,10 NC (No Connection)
