產品簡介

Grove - LCD RGB Backlight是一款16x2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作為控制芯片. 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。支持用戶自定義字符，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 接口，可以方便的和Arduino/Seeeduino連接，這是你在一些只需要顯示少量信息的場合的最佳選擇。

規格參數

• 供電電壓：5V
• 工作電流：< 60mA
• CGROM：10880 bit
• CGRAM：64*8 bit
• 多彩 的RGB 背光燈
• 內置英語日語字庫
• I2C 通信方式，節省IO口
• 自動上電復位

應用實例

這個實例會向你展示如何使用Grove - LCD RGB Backlight, 另外，我們需要一塊Seeeduino V3.0。

硬件連接

連接非常簡單，只需要通過一根Grove線連接到Seeeduino的I2C接口。

下載代碼

你可以到github下載驅動庫，點這裡。下載完之後，把它放到Arduino的libraries裡面。

Hello World

在庫裡面有個Hello World的example，我們將他打開，並且燒錄燒錄到Seeeduino V3.0。
你可以看到在LCD的第一排顯示了「Hello world」, 第二排顯示的是開機時間。

改變背光的顏色

Grove - LCD RGB Backlight很重要的一個特點在於可以改變背光的顏色，可以使用一下的函數方便改變背光顏色：

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

換個紅色的背光試試吧。
把代碼的顏色部分改成：

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

重新燒錄代碼，你可以看到，背光變成紅色的了，接下來，試試其他的顏色吧，讓你的LCD炫起來。

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)
