Arduino Code Operation

A 16×2 LCD display is very basic module and is very commonly used in various devices and circuits. More recent compatible chips are available with higher resolution, matched to displays with more pixels. Click to learn more about internal structure of a LCD. Selecting 4-bit or 8-bit mode requires careful selection of commands. Low to write to the register; High to read from the register.

How to use fixed point maths to save microcontroller memory by avoiding use of the floating point library.

Interface GPS with Arduino. Thanks so much for your time and works. Observe the Bit names: In other projects Wikimedia Commons.

Supply voltage; 5V 4. Sanchez, Julio; Canton, Maria P. This page was last edited on 17 Septemberat It’s clever and works in all cases but again there is a performance hit. The Hitachi HD has many commands, Here are the most useful: An Introduction to Software and Hardware Interfacing 2nd ed. hitaxhi


16 x 2 LCD Datasheet | 16×2 Character LCD Module PINOUT

Three different ways to debounce input push switches with one amazing method that you can’t miss. Contrast adjustment; through a variable resistor. DDRAM content hotachi unchanged. Sends data to data pins when a high to low pulse is given. This is an overloaded function that can print any of the three number types or a string. You can use this information to display a horizontal bar graph.

DDRAM content remains unchanged. How to use the BMP for weather pressure measurement or altitude change detection. LCD 16 x 2 Basics. 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.

Returns cursor to home position.

In this LCD each character is displayed in 5×7 pixel matrix. This would ensure that if other code accidentally set the pin direction wrongly then this would override it. Virgin Galactic — Commercial Space Flight. Time since last reset Example 3: Skip to main content. No reprodction without permission. Hitachi Liquid crystal displays Display devices. There’s nothing wrong with the code but it has to do a lot of manipulation to make the operation generic.


Secondly to manipulate each data bit to direct it to the output takes a few operations involving selecting the pin and then shifting the value right. Backlight V CC 5V. A 16×2 LCD means it can display 16 characters per line and there are 2 such lines. The nominal operating voltage for LED backlights is 5V at full brightness, with dimming at lower voltages dependent on the details such as LED color.

The commonly used instructions are shown in the instruction set below. Warning Some HD Displays have the 16 connection pins on lower edge of the pcb – so you might get it upside down – It is probably best if to test out the display on a solderless breadboard if unsure of the display orientation.
