'Keyboard'未在此范围内声明 - Arduino 编码

Question

我正在为Arduino编写一个简单的程序，该程序将输入2个按钮和输出模拟键，以在克隆英雄中使用2个不同的功能。

arduino编辑器（在线和本地版本）吐出

'Keyboard' was not declared in this scope

离线编辑器询问是否包括键盘。

有什么想法为什么？

// Keyboard - Version: Latest
#include <Keyboard.h>
//btnWhammy is the button to replace whammy bar function
//btnSP is the button to replace star power activation
//Set Clone Hero to register j for whammy and k for star power
//declaring constant integers for the pins on the Arduino
const int btnWhammy = 2;
const int btnSP = 13;
//Declaring integers for the state of the button press
int btnWhammyState = 0;
int btnSPState = 0;
void setup() {
  //Initialisation of the pins as inputs
  pinMode(btnWhammy, INPUT);
  pinMode(btnSP, INPUT);
}
void loop() {
  //Setting the button states to the read of the digital pin (LOW is off, HIGH is on)
  btnWhammyState = digitalRead(btnWhammy);
  btnSPState = digitalRead(btnSP);
  //If the whammy button is pressed, send 'j' to the keyboard, wait 100ms then release all keys
  if (btnWhammyState == HIGH) {
    Keyboard.press('j');
    delay(100);
    Keyboard.releaseAll();
  }
  //If the Star Power button is pressed, send 'k' to the keyboard, wait 100ms then release all keys
  if (btnSPState == HIGH) {
    Keyboard.press('k');
    delay(100);
    Keyboard.releaseAll();
  }
}

Answer 1

这是一个经典的错误 - 您可能正在为非Leonardo董事会编译，例如UNO。不包括键盘。h库，因为它不适合您要编译的板。

。

我拿了您的代码并为Leonardo编辑 - 没有问题。对于uno，我遇到的错误与您相同...

在此范围中没有声明键盘键，我发现了一个非常简单且有效的问题，只需转到您的主文件，您可以在其中声明您面对的所有其他键note

#include <DigiKeyboard.h>
#define KEY_UP_ARROW   0x52
#define KEY_DOWN_ARROW   0x51
#define KEY_LEFT_ARROW   0x50
#define KEY_RIGHT_ARROW   0x4F
#define KEY_TAB 0x2B
