Display_Example.ino is the main source of the sketch.

The sample application is organised in several files: If some of the functions included in the skeleton are not needed in your sketch for display purposes you can easly remove them without problems. This sketch should be intended as a modificable skeleton, where you should add your program the skeleton sketch, when compiled for Arduino UNO or Arduino Duemilanove, occupy less than 2,5 Kb of the 32Kb of available memory space.

The sample application can be downloaded from here with the html interactive documentation and the PDF manual. It is a set of helper mathods to manage the LCD Alphanumeric display through the AlphaLCD library. Instead of the traditional – and in most case too obvious – “hello world” sketch we have added a sample application including a couple of source tips to simplify the usage of the LCD output everywhere in the sketch. We suggest to take a look at the documentation to see the changes and how the library works. The AlphaLCD library is derived by the original LCDShift library (you can find it in our previous article) with some small changes including a complete documentation also available separately in two formats: html interactive documentation AlphaLCD HtmlDoc and PDF AlphaLCD Manual. Unzip the file and put the folder in in your Arduino library folder, so it can be used in the sketch, then restart the Arduino IDE. The AlphaLCD Library for Arduinoįirst you should download the AlphaLCD library for Arduino.

While the Alphanumeric LCD project for Arduino hardware aims to be simple, cheap and save as much as possible the available I/O ports (only three pins are used), in the same way the software to manage the display should fit leaving a reasonable free amount of memory for data and application firmware. The idea beside this project is to give a simple output empowering the Arduino board behavior without compromising the sketch space. As promised in the first part of this article, now it is time to see in detail how we can use the Alphanumeric LCD Display in our Arduino sketches.
