Place data byte on the data register. For displaying a character you should enable the enable pin pin 6 by giving a pulse of ns, after enabling the pin6 you should select the register select pin pin4 in write mode. The below sample code shows how to use the already available LCD functions. This LCD can be operated in 4-bit mode using only 4 data lines or 8-bit mode using all 8 data lines. I Made It!
