The details of the lcd.createChar() function are discussed in the following section.

#CODING LCD ARDUINO CODE#

The code written for this project has a function lcd.createChar() which helps to create the custom characters in an LCD screen.

#CODING LCD ARDUINO HOW TO#

The details of those functions are already discussed in the previous projects on how to interface an LCD, how to display sensor value on LCD, how to connect the LCD with the PC and how to make an LCD scrolling display. Few functions from the library are used in this project also which are actually very useful in small applications. The Arduino IDE has a library called which provides lot of functions to access the LCD module. 7: 8*5 Pixel And Binary Array For Negative Half Cycle Of Smileys The 8*5 pixel array and the corresponding binary array for the heart symbol displayed in the project are shown in the following image įig. The 8 byte long character array for the above shown custom character can be defined in the code as given below 6: 8*5 Pixel And Binary Array For Positive Half Cycle Of Smileys The 8*5 pixel array and the corresponding binary array for the smile symbol displayed in the project are shown in the following image įig. The bit patterns that need to be stored in the LCD to display those characters are find out using the method of drawing the pixel array and assuming the bit value for the pixel which is ON as 1and the pixel which is off as 0. There are basically two symbols used in this project of which one is a smile symbol and another is a heart symbol. 5: Custom Character On LCD Using Arduino Circuit On Breadboard The custom characters which are displayed in this project are shown in the following image.įig. One has to work out the character of the custom character that needs to be displayed in the LCD screen as explained in the project on how to create custom characters in an LCD. The method of generating custom characters is well explained in a previous project on how to create custom characters in an LCD. The LCD modules also provide a CGRAM where the user can store the custom characters and display them. The ASCII character patterns are stored in the internal CGROM of the LCD controllers. The LCD module has two or more controllers which helps in displaying the characters corresponding to the ASCII value which is send by the microcontroller. This project makes use of the custom characters that can be generated in an LCD module. It is assumed that the reader has gone through the project how to get started with the arduino and done all the things discussed in it.

4: External USB to TTL converter board for programming Arduino and serial communication The image of the Arduino pro-mini board and the Arduino IDE is shown in the following Īnother hardware which can perform the USB to TTL conversion is used to upload the program into the arduino board.įig.

#CODING LCD ARDUINO WINDOWS#

In this project the Arduino pro-mini board is used which is then programmed with the help of Arduino IDE version 1.0.3 on windows operating system. The libraries in the Arduino IDE help in accessing the LCD module very easily. Since the basic Arduino board does not have a built –in LCD module to display data one should connect it externally to display data like strings, sensor values etc. The Arduino is an easy-prototyping platform where the hardware is very simple and the coding and IDE is very easy to start with. The project is done with the help of easy-prototyping platform Arduino.

This particular project demonstrates how is it possible to create a smiley and display it in a 16x2 LCD. Smileys are now a days very popular especially in SMS using mobile phones, online messenger applications etc. The custom characters can be used to display various kinds of smileys in LCD display. The custom characters are used for the dynamic display in an LCD board.

The stored custom character can be made to display by sending the corresponding value to the LCD module. The user can store the pixel array corresponding to the custom character in an LCD module.

The LCD modules can display not only ASCII characters but custom characters also. The LCD module is very effective since it can display messages, values, clock etc.

Special kind of Liquid Crystal drivers are used with the commonly found LCD modules in microcontroller systems. In case of a microcontroller based system the LCD is the most effective output device. Liquid Crystal Display (LCD) is made use in various kinds of devices from small display screen in calculator to large screens in televisions.
