LCDDriver_NXP_Arduino

LCD driver device operation sample code for Arduino

Note This library works with I2C_device library together. Please be sure the I2C_device library is imported in your environment before trying to build.

PCA8561AHN-ARD : Arduino® Shield Evaluation Board for LCD driver

What is this?

An Arduino library for I²C LCD driver with sample code.
This library provides simple API to display characters on the LCD.
Include device name header file (PCA8561.h) to use those class libraries.

With LCDDriver_NXP_Arduino library, characters can be shown by next sample code.

#include <PCA8561.h>

PCA8561 lcdd;

void setup() {
  Wire.begin();
  lcdd.begin();  // This is necessary to enable display; device goes into power-on mode

  lcdd.puts("BEER");
}

void loop() {
}

Supported device

Type#	Header file	Features	Interface	Evaluation board
PCA8561	PCA8561.h	18 X 4 LCD Segment Driver	I²C Fast-mode (400KHz)	PCA8561 18 × 4 LCD Segment Driver Arduino® Shield

Getting started

Use Library manager in Arduino IDE for easy install

Examples

Examples are provided as scketch files.

How to use?

After library install, Choose menu on Arduino-IDE: File→Examples→LCDDrivers_NXP_Arduino→ sketch for your try

List of sample code

Sketch	Target	Feature
PCA8561_simple	PCA8561	Simple sample for just showing "TEST" on LCD
PCA8561_string_scroll	PCA8561	Shows string scrolling feature
PCA8561_lib_test	PCA8561	Test code for all library features

TIPS

If you need to use different I²C bus on Arduino, it can be done like this. This sample shows how the Wire1 on Arduino Due can be operated.

#include <PCA8561.h>

// PCA8561 lcdd; // This line was changed to below
PCA8561 lcdd(Wire1);

void setup() {
  // Wire.begin(); // This line was changed to below
  Wire1.begin();
  lcdd.begin();  // This is necessary to enable display; device goes into power-on mode

  lcdd.puts("BEER");
}

void loop() {
}
