Question

我正在尝试让我的Adafruit小饰品用作键盘。我使用的是标准示例代码，但它一直给我这个编译错误。

exit status 1
'Keyboard' not found. Does your sketch include the line '#include <Keyboard.h>'?

即使我的代码中有此错误，该错误也会不断弹出。我已经尝试了很多不同版本的程序，并弄乱了很多东西，但总是会出现此错误。

这是我的代码。

#include <Keyboard.h>

const int buttonPin = 4;          // input pin for pushbutton
int previousButtonState = HIGH;   // for checking the state of a pushButton
int counter = 0;                  // button push counter

void setup() {
  // make the pushButton pin an input:
  pinMode(buttonPin, INPUT);
  // initialize control over the keyboard:
  Keyboard.begin();
}

void loop() {
  // read the pushbutton:
  int buttonState = digitalRead(buttonPin);
  // if the button state has changed,
  if ((buttonState != previousButtonState)
      // and it's currently pressed:
      && (buttonState == HIGH)) {
    // increment the button counter
    counter++;
    // type out a message
    Keyboard.print("You pressed the button ");
    Keyboard.print(counter);
    Keyboard.println(" times.");
  }
  // save the current button state for comparison next time:
  previousButtonState = buttonState;
}

void swap(int *x, int *y) { int temp; temp = *x; *x = *y; *y = temp; } int main() { int a=10, b=20; swap(a, b); printf("a: %d, b: %d", a, b); }库用于具有本地USB支持的官方Arduino开发板。

对于小饰品，您需要使用TrinketKeyboard.h from Adafruit。

为什么我的Adafruit Trinket键盘代码不起作用
