I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work.
We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and text display features. It can replace the serial monitor of Arduino in some place, you can get running informations without a computer.
More than that, we also develop the dedicated picture data convert software (bitmap converter)now is available to support PC platform of windows, Linux, Mac OS. Through the bitmap convert software you can get your favorite picture displayed on I2C_LCD, without the need for complex programming.
I2C_LCD can provide you with a very convenient way of make. Enjoy yourself!

Step 1: Install the latest version of Arduino IDE to your computer.
Step 2: Download and install the I2C_LCD library to Arduino IDE:
Open Arduino IDE, click Sketch -> Include library -> Add .ZIP library.
Find and select the I2C_LCD.zip file you just downloaded.
Restart the Arduino IDE.
Step 3: Chose the example project which you like. (Take "HelloWorld" project for example here.)
Click File > Examples > I2C_LCD > HelloWorld
Step 4: Connect I2C_LCD to your Seeeduino Vx board with Grove cable. Then connect Seeeduino Vx board to your computer.
Step 5: Select your board and serial port.
Select the board: Click Tools > Board > "Arduino Duemilanove or Diecimila"(Seeeduino V3.0 Or early version), "Arduino Uno"(Seeeduino Lotus or Seeeduino V4.0).
Select the COM: Click Tools -> Serial Port -> COMX(which connected with your board.)
Step 6: Upload the program and enjoy yourself!
