It is driver for LCD_Matrix suitable for Atmega32 the project include src code of driver and hex file (for Atmega32) the driver has flexibility to connect LCD 5x7matrix (D4-D7, 4bit) "OR" 5x7matrix (D0-D7, 8bit)
I separated the Project into: header file "prototype.h" -- implementation file "prototype.c" -- MainProgram "main.c"
For defines(that is where you can customize PORTs & Pins) , implementation of needed function and main program respectively.
#included suggested linking of LCD to Atmega32
NOTE: attach VEE to potentiometer to Adjust contrast in simulation I attached this to GND Also,...I assumed that I will be write to screen only so I attached R/W pin to GND
