LCD Interfacing with PIC microcontroller LCD (Liquid Crystal Display): In recent years the Alphanumeric display(Liquid Crystal Display) has been finding widespread and replacing "Seven segment display". Why we prefer LCDs over LEDs.............. 1. The declining cost of LCDs. 2. The LCD's can display numbers, characters, and graphics. In contrast, LEDs, which are confined to display numbers and a few characters. 3.Manfacturers provide built in controller with LCD to control refresh rate as a result no need to write code in PIC18 for that task. Conversely, separate routine is required to refresh LEDs to carry displaying the information. 4. Simple programming for characters and graphics. More importantly, LCD current(mA) requirement in comparison of seven segment displays is considerably low. Furthermore, Latest LCDs modules permit the coder to define custom character and graphics. Once you find out how to i...
