Teensy 3.2 Hellokeypad草图编译错误

Question

当我尝试编译HelloKeypad演示草图时，我得到了一个编译器错误。

我使用的是一台Windows7计算机，使用的是一个很小的3.2主板。

我买了一个像这样的键盘：https://www.adafruit.com/products/1824

我从这里下载了keypad.zip文件：https://www.pjrc.com/teensy/td_libs_Keypad.html，我使用的是同一个网页上的示例草图：

/* @file HelloKeypad.pde
|| @version 1.0
|| @author Alexander Brevig
|| @contact alexanderbrevig@gmail.com
||
|| @description
|| | Demonstrates the simplest use of the matrix Keypad library.
|| #
*/
#include <Keypad.h>

const byte ROWS = 4; //four rows
const byte COLS = 3; //three columns
char keys[ROWS][COLS] = {
  {'1','2','3'},
  {'4','5','6'},
  {'7','8','9'},
  {'*','0','#'}
};
byte rowPins[ROWS] = {5, 4, 3, 2}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {8, 7, 6}; //connect to the column pinouts of the keypad

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

void setup(){
  Serial.begin(9600);
}

void loop(){
  char key = keypad.getKey();

  if (key){
    Serial.println(key);
  }
}

以下是编译器消息。

Keypad.zip文件是否已过期？

谢谢你的帮助。

Answer 1

可以使用Arduino IDE 1.6.3而不是1.6.6。

根据pjrc forum中的以下post，它解决了库支持的问题。
