how to interface 16×2 LCD with microcontroller (AT89C51) – CONSBEDDED

Interface GPS with Arduino. Arduino based GPS receiver.

A 16x 2 LCD means it can display 16 characters per line and there are 2 such lines. The necessary commands for the LCD initialization are defined at the end part of the program. The reset circuit, oscillator circuit and power supply need to be provided for the proper working of the circuit.

Sorry for the question. Each write operation is performed on the positive edge of the Enable signal.

Choosing Battery for Robots. Power supply to control contrast. As shown in the circuit diagram, port 0 of the controller is used for interfacing it with LCD module. High level at this pin enables read mode and low level at this pin enables write mode.


I think that you have use array in c programming. See the circuit diagram for better understanding.

It is very important to keep a track of the working of almost all the automated and semi-automated devices, be it a washing machine, an autonomous robot or anything else. Data register is for placing the data to be displayedand the command register is to place the commands. Data Register – stores the data to be displayed on the LCD.

LCD interfacing with Microcontroller (AT89C51) – Circuit & C Program

E pin is for enabling the module. Commonly used LCD Command codes: SPI Module of Arduino. This will saves the number of GPIO pins needed for other purpose. In this LCD each character is displayed in 5×7 pixel matrix. This is achieved by displaying their status on a small display module. El retardo es demasiado corto. Anybody can send me the programing for lcd interfacing with microcontroller and xbee s2. Hi I constructed the circuit exactly as it is on my simulator t just copied the program and nothing is appearing on the LCD.


Force cursor to the beginning of the 2 nd line. LCD Liquid Crystal Display screen is an electronic display module and find a wide range of 1×62. Pls provide alp programs for LCD interfacing. The module were are talking about here is type number JHDA which is a very popular one. As mentioned earlier the 8 bit data is break into two 4 bit data and send to LCD.

These modules are replacing seven segments and other multi segment LEDs for these purposes. Also instruction command codes are sent to these pins. Pulse E from high to low. POT R2 is used for adjusting the contrast of the display. DB0 to DB7 are the data pins.
