Arduino SPI LCD Shield 在Pcduino上完美运行

EEbird

只需要简单的几步，我们就可以在Pcduino上运行Arduino SPI LCD Shield了，以下是简单的方法演示步骤：
一、 在Linker Base Shield 上的连线方式如图1、2

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 Digital 2
* SDA to Digital 3
* LAT to Digital 4
*
/ include the library code:
#include <core.h>
#include "Wire.h"
#include "LiquidCrystal.h"
// Connect via SPI. Data pin is #3, Clock is #2 and Latch is #4
LiquidCrystal lcd(11, 13, 10);
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);
}
