操作演示如下：
一、 I2C的连线方式如图
正面
背面
二、线路连接好之后，打开LXTerminal，进入目录，如图所示
三.打开代码，见下图
四、、代码打开成功之后，输入make进行编译，出现可执行文件，如下图
五、 运行代码，简单快捷的I2C通信就能在您的Pcduino上实现了
/*
This sketch prints "Hello World!" to the LCD
and shows the time.
The circuit:
* 5V to Arduino 5V pin
* GND to Arduino GND pin
* SCL to Analog #5
* SDA to Analog #4
*/
// include the library code:
#include
#include "Wire.h"
#include "LiquidCrystal.h"
// Connect via i2c, default address #0 (A0-A2 not jumpered)
LiquidCrystal lcd(0);
void setup() {
// set up the LCD's number of rows and columns:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("hello, world!");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
lcd.setBacklight(HIGH);
delay(500);
lcd.setBacklight(LOW);
delay(500);
}
