Display units are the most important output devices in embedded projects and electronics products. 16x2 LCD is one of the most used display unit.
16x2 LCD means that there are two rows in which 16 characters can be displayed per line, and each character takes 5X7 matrix space on LCD. In this tutorial we are going to connect to the 8051 microcontroller (AT89S52). Interfacing LCD with 8051 microcontroller might look quite complex to newbies, but after understanding the concept it would look very simple and easy.
Listing Program Mikrokontroler At89s51
Although it may be time taking because you need to understand and connect 16 pins of LCD to the microcontroller. So first let's understand the 16 pins of LCD module.
KEIL uVision is the name of a software dedicated to the development and testing of a family of microcontrollers based on 8051 technology, which we are going to use along this tutorial. You can can download an evaluation version of KEIL at their website:.
