Story

Introduction

In this December month the Silícios Lab presented some content with Christmas themes and in this content, you'll learn how to send a message for LCD 16x2 using Flowcode 7. And for this, we use the Christmas message.

Happy Christmas for you, my reader!

Video 1 - Send string for LCD 16x2 with Arduino UNO and LCD 16x2.

The Circuit

In Figure 1 is presented the circuit with Arduino and LCD 16x2 to show the Christmas message using Flowcode 7.

Figure 1 - Circuit of LCD 16x2 with Arduino Controller.

For construct, the circuit was used a LCD 16x2 configuration with 4 pins for data, Register select pin and Enable pin.

In the following topic will be explained the flowchart constructed with Flowcode 7.

Flowchart with Flowcode 7

In the Flowchart presented in Figure 2 you can see the construction process to mount the programming logic. If you can not see the flowchart, click on the image with the right mouse button and open the image in a new tab or click on it to download the flowchart image (Link - Download).

Figure 2 - Flowchart with Christmas Message.

As you see in the image, the Flowcode has various macros of functions of the LCD 16x2 in the Flowcode 7.

In the Flowchart were used 5 different macro types/functions to program the LCD 16x2. Firstly, was used the macro/function to initialize the LCD 16x2. After this, in the loop the messages will be shown using other functions: DisplayCursor to position the stroke at a specific position on the 16x2 LCD, PrintString to print the message on the LCD screen and delays for the message be read for the user.

The Macro DisplayCursor is used to put the cursor in a determined position of LCD 16x2, the PrintString Macro is used to print the message in a position determined by the DisplayCursor macro and the delay is used to generate a delay in application.

Application

This message system can be used in applications that need to present some messages, for example, company name, an interactive message with the user and among other messages when the system is not being used by the user.
