LCD interfacing with PIC16F84A using CCS PIC C compiler

PIC16F84A LCD example with CCS C
 PIC16F84A LCD example hardware circuit

It is easy to interface LCD displays with PIC16F84A microcontroller using CCS PIC C compiler since the compiler has its driver.
There are 7 data lines between the microcontroller and the LCD display which are: RS, R/W, E, D4, D5, D6 and D7. The following PIC16F84A LCD example shows how to connect the LCD screen with the microcontroller and how to display characters using CCS C compiler.
