(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。wiring_digital-error: digitalWrite: can't index pinState with pin 9

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。 本帖最后由 Angelo 于 2015-5-21 14:33 编辑

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 = d0;
_data_pins = d1;
_data_pins = d2;
_data_pins = d3;
_data_pins = d4;
_data_pins = d5;
_data_pins = d6;
_data_pins = 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);
}

我测试了下，是这样子的。强！
