In normal cases we need only writing hence it is tied to GROUND in circuit shown below. Enable (E) input of the LCD is used to give Data Strobe. HIGH (5V) Voltage Level in the Enable (E) pin tells the LCD that DB0 – DB7 contains valid information. The input signal R/W (Read or Write) determines whether data is written to or read from the LCD. When RS is HIGH LCD treats DB0 – DB7 data pins information as Data to be displayed and when it is LOW LCD treats it as Command Information. Data and Command Information are send to LCD through same data lines (DB0 – DB7) which are multiplexed using RS (Register Select) pin of LCD. Data Information is the ASCII value of the characters to be displayed in the LCD screen and Command Information determines other operations such as position to be displayed, clear screen, shift etc. A microcontroller or microprocessor need to send 2 types of information for operating this LCD Module, Data Information and Command Information. A 10KΩ preset whose fixed ends connected to VDD, VSS and variable end connected to VEE can be used to control contrast of the LCD. 3 ed pin VEE is used to control the contrast of the LCD display. 16×2 LCD Pin Diagramįirst two pins GND and VCC (VSS and VDD) are for providing power to LCD display. Don’t worry we already developed an LCD library including commonly used functions, so you can use it without any hardware knowledge of LCD. So we need to learn HD44780 Dot Matrix LCD Controller Datasheet.

These LCDs commonly uses HD44780 compliant controllers. In these displays, each character is displayed using 5×8 or 5×10 dot matrix.įor controlling LCD using MPLAB XC8 compiler we need to know the hardware of LCD. Its other variants such as 16×1 and 16×4 are also available in the market.

16×2 means it contains 2 rows that can display 16 characters. 16×2 Character LCD is a very basic and low cost LCD module which is commonly used in electronic products and projects. In this tutorial we will see How to Interface a 16×2 character LCD module with PIC 16F877A Microcontroller using MPLAB X IDE and MPLAB XC8 C Compiler.
