Here we have
interfaced LCD with AT89c51. LCD has 16 pins, in that 8 pins for data, and 3
pins for controlling lcd.
But in 8051, we have totally 32 pins for interfacing. so if we use 11 pins for LCD interfacing, then only few pins will be available for others.
So we interface LCD in 4 bit mode. So We need 4 pins for Data and 2 pins(RS,EN) for controlling.
So that we reduce 5 pins.
For lcd in 4bit mode with dancing display,
This code is compiled in keil uvision 3 and simulated in proteus simulation software.
here you can use this in advertisement display boards,
get code, circuit diagram and simulation.
