Grove – LCD RGB Backlight – RGB 全彩背光 炫彩背光 LCD

Grove – LCD RGB Backlight 是一款16×2的LCD顯示器。如果你之前使用過Grove – Serial LCD, 那麼你應該對1602的LCD不會陌生,不同的是Grove – LCD RGB Backlight採用了RGB的背光燈. Grove – LCD RGB Backlight內部使用低功耗CMOS技術的AIP31068L作為控制晶片. 整個模塊使用I2C的通信方式,只需兩個IO口即可完成控制,省下來的IO,你可以用來做更多有意義的事情。支援用戶自定義字元,想在LCD上打出一個愛心?這只是一件很簡單的事情。另外,多彩的RGB背光,使你的應用更加奪目絢麗。Grove – LCD RGB Backlight 採用標準的4pin Grove 介面,可以方便的和Arduino 連接,這是你在一些只需要顯示少量資訊的場合的最佳選擇。

Grove – LCD RGB Backlight

Grove – LCD RGB Backlight is a full-color backlight 16×2 LCD. High contrast and ease of use make it a perfect I2C LCD display for Arduino and Raspberry Pi.

The traditional 1602 LCD requires up to 10 I/O pins to display, and the 1602 LCD with RGB backlight requires an extra 3 pins to control the backlight color. This will take up a lot of I/O pins on the main control board, especially for development boards with less I/O resources such as Arduino and Raspberry Pi. Grove – LCD RGB Backlight makes it totally different! With the help of Grove I2C connector, only 2 signal pins and 2 power pins are needed. You don’t even need to care about how to connect these pins. Just plug it into the I2C interface on Seeeduino or Arduino/Raspberry Pi+baseshield via the Grove cable. No complicated wiring, no soldering, no need to worry about burning the LCD caused by the wrong current limiting resistor. Easy peasy.

What’s more, this LCD module is not only a character LCD but also can display your DIY images, such as a heart and a smiling face. 16×2 means two lines and each line have 16 columns, 32 characters in total. Each character contains 5*8 pixels. You can check here to make your own images array, just release your creativity and imaginations.

Features

  • Full-color RGB Backlight
  • High contrast, clearly visible in direct sunlight
  • I2C communication uses only two I/O pins
  • Automatic power-on reset

 

Introduction

Done with tedious mono color backlight? This Grove enables you to set the color to whatever you like via the simple and concise Grove interface. It takes I2C as communication method with your microcontroller. So number of pins required for data exchange and backlight control shrinks from ~10 to 2, relieving IOs for other challenging tasks. Besides, Grove – LCD RGB Backlight supports user-defined characters. Want to get a love heart or some other foreign characters? Just take advantage of this feature and design it!

 

Specification

  • Input Voltage:5V
  • Operating Current<60mA
  • CGROM: 10880 bit
  • CGRAM: 64*8 bit
  • Colorful RGB Backlight
  • Built-in English and Japanese fonts
  • I2C communication, uses only two IOs
  • Automatic power-on reset
  • Suli-compatible Library

Demonstration

This demonstration will show you how to use Grove – LCD RGB Backlight, we need a Seeeduino V3.0 else.

Hardware Installation

Hardware installation is very easy, because there’s an I2C Grove in Seeeduino,
so what we need to do is connect it to I2C Grove via a Grove cable.

Download Code and Upload

You can download the demo code in github, click here, then extract it to anywhere.

there is a Hello World example in the library, open it, and upload to Seeeduino V3.0.
then you can see “Hello world” on the first row, and second row will print the number of second since reset.

Change Color of Backlight

One of Grove – LCD RGB Backlight’s most important feature is: you can change the color backlight, and it’s a very simple thing, just use the following function:

void setRGB(int r, int g, int b);

Then let’s try a Red backlight.

Modify the code about color into :

const int colorR = 255;
const int colorG = 0;
const int colorB = 0;

Upload the code again, woo, see the backlight turn to Red? Then why not try another color? Whatever you like.

With Raspberry Pi

This example will change backlight color and display text. You should connect to GrovePi+ with it like the following picture.

# Grovepi + grove RGB LCD module
 
# Example for using the Grove I2C color LCD
from grove_rgb_lcd import *

while(True):
    setText("Hello world\nLCD test")
    setRGB(0,128,64)
    for c in range(0,255):
        setRGB(c,255-c,0)
        time.sleep(0.01)
    setRGB(0,255,0)
    setText("Bye bye, this should wrap")
    time.sleep(1.5)

Run The Program

  • Find the path to the file(According to your own path)
   cd GrovePi/Software/Python/grove_rgb_lcd/
  • Run program
    sudo python example.py
