Question

我在我的草图中引用了IRQn_Type和Tc类型（对于找到的here的startTimer函数），但是我得到一个编译错误，说这些类型“未在此范围内声明”。这些“内置”类型不是吗？如果没有，是否有必须包含的标题？

Dan，如果您正在尝试中断，这里是Arduino SE网站的列表并在gcc avr头文件中定义。我用来在Atmel Studio中用C编程AVR的那些：

#define INT0_vect         _VECTOR(1)   /* External Interrupt Request 0 */
#define INT1_vect         _VECTOR(2)   /* External Interrupt Request 1 */
#define PCINT0_vect       _VECTOR(3)   /* Pin Change Interrupt Request 0 */
#define PCINT1_vect       _VECTOR(4)   /* Pin Change Interrupt Request 0 */
#define PCINT2_vect       _VECTOR(5)   /* Pin Change Interrupt Request 1 */
#define WDT_vect          _VECTOR(6)   /* Watchdog Time-out Interrupt */
#define TIMER2_COMPA_vect _VECTOR(7)   /* Timer/Counter2 Compare Match A */
#define TIMER2_COMPB_vect _VECTOR(8)   /* Timer/Counter2 Compare Match A */
#define TIMER2_OVF_vect   _VECTOR(9)   /* Timer/Counter2 Overflow */
#define TIMER1_CAPT_vect  _VECTOR(10)  /* Timer/Counter1 Capture Event */
#define TIMER1_COMPA_vect _VECTOR(11)  /* Timer/Counter1 Compare Match A */
#define TIMER1_COMPB_vect _VECTOR(12)  /* Timer/Counter1 Compare Match B */
#define TIMER1_OVF_vect   _VECTOR(13)  /* Timer/Counter1 Overflow */
#define TIMER0_COMPA_vect _VECTOR(14)  /* TimerCounter0 Compare Match A */
#define TIMER0_COMPB_vect _VECTOR(15)  /* TimerCounter0 Compare Match B */
#define TIMER0_OVF_vect   _VECTOR(16)  /* Timer/Couner0 Overflow */
#define SPI_STC_vect      _VECTOR(17)  /* SPI Serial Transfer Complete */
#define USART_RX_vect     _VECTOR(18)  /* USART Rx Complete */
#define USART_UDRE_vect   _VECTOR(19)  /* USART, Data Register Empty */
#define USART_TX_vect     _VECTOR(20)  /* USART Tx Complete */
#define ADC_vect          _VECTOR(21)  /* ADC Conversion Complete */
#define EE_READY_vect     _VECTOR(22)  /* EEPROM Ready */
#define ANALOG_COMP_vect  _VECTOR(23)  /* Analog Comparator */
#define TWI_vect          _VECTOR(24)  /* Two-wire Serial Interface */
#define SPM_READY_vect    _VECTOR(25)  /* Store Program Memory Read */

我正在为Arduino Due编译，但我没有在Tools |下选择该板板。一旦我这样做，我就能编译。

'IRQn_Type'和'Tc'未定义编译Arduino sketch的错误
