(SKU:DFR0009)LCD Keypad Shield的例子程序在我的板子上不work

我把LCD的例子程序，烧写到我的板子上，不work。然后用别人的笔记本，编译烧写到我的Edison板子上，可以work。

我的报错信息如上所述，我是直接./sketch.elf后，报的错误信息！

应该是Arduino IDE的问题, 可以尝试重新安装一下:

另外Edison的固件也有更新过, 可以尝试跟着这个教程更新一下
http://www.intel.com/support/edison/sb/CS-035286.htm

我表示看不懂报错信息

奇葩的问题还真是奇葩的解决了
    问题出在： Arduino IDE，编译出问题。
                       我的Arduino IDE 是 arduino-1.6.0+Intel
                        换成arduino-1.5.3-Intel.1.0.4，就O了，真奇葩。

Edison 1.6.0 里面存在一个问题, LiquidCrystal这个类在构造函数里面调用了pinMode()函数,但此时 pinMode()函数还无法使用, 因此我们需要手动在 Setup 里面添加pinMode(), 让引脚变为输出模式

void LiquidCrystal::init(uint8_t fourbitmode, uint8_t rs, uint8_t rw, uint8_t enable,
                         uint8_t d0, uint8_t d1, uint8_t d2, uint8_t d3,
                         uint8_t d4, uint8_t d5, uint8_t d6, uint8_t d7)
{
  _rs_pin = rs;
  _rw_pin = rw;
  _enable_pin = enable;
  
  _data_pins[0] = d0;
  _data_pins[1] = d1;
  _data_pins[2] = d2;
  _data_pins[3] = d3;
  _data_pins[4] = d4;
  _data_pins[5] = d5;
  _data_pins[6] = d6;
  _data_pins[7] = d7;

  pinMode(_rs_pin, OUTPUT);
  // we can save 1 pin by not using RW. Indicate by passing 255 instead of pin#
  if (_rw_pin != 255) {
    pinMode(_rw_pin, OUTPUT);
  }
  pinMode(_enable_pin, OUTPUT);
  
  if (fourbitmode)
    _displayfunction = LCD_4BITMODE | LCD_1LINE | LCD_5x8DOTS;
  else
    _displayfunction = LCD_8BITMODE | LCD_1LINE | LCD_5x8DOTS;
  
  begin(16, 1);  
}

一下是测试代码:

#include <LiquidCrystal.h>

LiquidCrystal lcd(8, 9, 4, 5, 6, 7);        // 初始化LCD的引脚号

void setup() {
    pinMode(8, OUTPUT);
    pinMode(9, OUTPUT);
    pinMode(4, OUTPUT);
    pinMode(5, OUTPUT);
    pinMode(6, OUTPUT);
    pinMode(7, OUTPUT);
  lcd.begin(16, 2);  // 设置LCD为2行，每行16个字符
}

void loop() {
  lcd.setCursor(0, 0); 
  lcd.print("Hello");
  delay(500);
}
复制代码

我测试了下，是这样子的。强！
