The Arduino IDE allows for various different ways of installing libraries.
#ARDUINO LCD LIBRARY EXAMPLES INSTALL#
Of course, it is worth having a look at the available examples, but for our needs it is enough to install the library saved in the LCD16x2 catalogue. At this point, we are looking for the link saying: "OLIMEXINO-328 + SHIELD-LCD16x2 – a library and set of demo examples".ĭownload the ZIP file available at this link to your computer. Each line of text in this section is also a link to a file that can be downloaded from the Olimex website. Under the description of the module, you can find the "SOFTWARE" section (figure 2). When this text was being created, the search retuned two results – please, select "SHIELD-LCD16x2".įigure 1: Section of the Olimex website with the search box Then, in the search box (next to the Search button) enter the part of the module name "LCD16x2". To install the library, go to the module manufacturer's website i.e. The second one requires you to install a library of module operating functions. The first one is simply to plug the shield into the Arduino UNO board. There are two steps to prepare the module for work: hardware and software. Let's start with preparing the module for operation.
With access to a library of functions, operating this module with a built-in microcontroller should not cause any major problems. On the board, there is a PIC processor which communicates with Arduino UNO via the TWI interface. This is a shield board which extends Arduino capabilities, equipped with an LCD module (2 lines of 16 characters each), 4 buttons and 8 additional GPIO lines. To do so, you need a keyboard, which we will discuss in detail in one of the future articles, but now let us use a ready-made solution from the Arduino ecosystem – a board from Olimex – SHIELDLCD16x2. Still, it needs to be admitted here that there is only a limited number of applications for an LCD alone, because in the case of such a simple LCD module no settings can be entered.

It contains a description of the LCD module, shows you how to connect the display to your Arduino UNO board and describes the basic rules of operating it using the software.
