Young Hu：

这是新的C2000的编程风格，采用类似面向对象的风格，定义了一段ADC的结构体，把所有的寄存器都封装在这个结构体中。

typedef struct ADC_Obj *ADC_Handle;

是定义一个指针，通过指针对ADC这个结构体进行操作。

ADC_Obj *adc = (ADC_Obj *)adcHandle;

定义一个局部变量指针，通过函数定义，可以将ADC结构体复制给这个局部指针。

这样保证了函数的可复用性。

inline，自己去网上查吧

//! \brief Defines the analog-to-digital converter (ADC) handle
//!
typedef struct ADC_Obj *ADC_Handle;

inline void ADC_clearIntFlag(ADC_Handle adcHandle, const ADC_IntNumber_e intNumber)
{
ADC_Obj *adc = (ADC_Obj *)adcHandle;

// clear the bit
adc->ADCINTFLGCLR = 1 << intNumber;

return;
} // end of ADC_clearIntFlag() function

重新开始：

回复 Young Hu:

谢谢您的解答

我还是有些不太懂

typedef struct _ADC_Obj_

{

····

}ADC_Obj;这已经声明了一个新结构体类型名ADC_Obj

而typedef struct ADC_Obj *ADC_Handle;这条语句怎么理解？我感觉按C语言应该是这样的typedef ADC_Obj *ADC_Handle;或者是

typedef struct _ADC_Obj_ *ADC_Handle;

//! \brief Defines the analog-to-digital converter (ADC) handle
//!
typedef struct ADC_Obj *ADC_Handle;

inline void ADC_clearIntFlag(ADC_Handle adcHandle, const ADC_IntNumber_e intNumber)
{
ADC_Obj *adc = (ADC_Obj *)adcHandle;

// clear the bit
adc->ADCINTFLGCLR = 1 << intNumber;

return;
} // end of ADC_clearIntFlag() function

10#：

回复重新开始:

通过typedef定义一个数据类型，再用同样的方式定义该类型的一个变量（这里是个指针）。

后面你列出的写法应该也是正确的，建议阅读一下C语言中关于typedef的使用说明确认一下。
