The four most significant bits must be written first, followed by the four least significant bits Low to write to the register; High to read from the register. Returns cursor to home position. Second, the LCD may initially be in one of three states:. State3 may occur, for example, if a prior control was aborted after sending only the first 4 bits of a command while the LCD was in 4-bit mode.

Sanchez, Julio; Canton, Maria P. Choosing Motor For Robots. These characters have to be written to the device each time it is switched on, as they are stored in volatile memory.

More recent compatible chips are available with higher resolution, matched to displays with more pixels. Interface GPS with Arduino.


A command is an instruction given to LCD to do a predefined task like initializing it, clearing its screen, setting the cursor position, controlling display etc. Selecting 4-bit or 8-bit mode requires careful selection of commands. Once in 4-bit mode, character and control data are transferred as pairs of 4-bit “nibbles” on the upper data pins, D7-D4.

Non-LED backlights often require higher voltages. A 16×2 LCD means it can display 16 characters per line and there are 2 such lines. A 16×2 LCD display is very basic module and is very commonly used in various devices and circuits. The data register stores the data to be displayed on the LCD.

A limited number of custom characters can be programmed into the device in the form of a bitmap using special commands. In this Llcd each character is displayed in 5×7 pixel matrix. Compatible LCD screens are manufactured in several standard configurations. Those without backlights may have only 14 pins, omitting the two pins powering the light.
