2 [2 f) ]; k+ e/ z& P 这里是一种条件编译。extern “C”指令非常有用，因为C和C++的近亲关系。注意：extern “C”指令中的C，表示的一种编译和连接规约，而不是一种语言。C表示符合C语言的编译和连接规约的任何语言，如Fortran、assembler等。6 `! k# I0 a/ i1 }' ~# d5 _
" Z: h! E- Y- D& o7 S( d
还有要说明的是，extern “C”指令仅指定编译和连接规约，但不影响语义。例如在函数声明中，指定了extern “C”，仍然要遵守C++的类型检测、参数转换规则。
! {+ u1 r( `, m一开始我不解 extern “C” { 这个语句的意思，原来是用来说明后面的定义都是使用C语言写的。这个 __cplusplus 是指C++来的，4、5句的意思就是说如果用C++编译器的话，它里面是定义有__cplusplus 这个的，而通过 extern “C” { 告知编译器，这段代码是用C编写的，要按照C语言编译。这是因为C++里面有函数重载，编译的时候把参数也编译了，而C的话，编译只编译函数名。

不同版本的标准外设库的变量定义略有不同，如3.4版本中就没有之前版本的TRUE和FALSE的定义，用户也可以根据自己的需求按照上面的格式定义自己的布尔形变量。在使用标准外设库进行开发遇到相关的定义问题时应首先找到对应的头文件定义 。2 X2 ^' S5 y5 C2 R

const是一个C语言的关键字，它限定一个变量不允许被改变。使用const在一定程度上可以提高程序的安全性和可靠性。另外，在观看别人代码的时候，清晰理解const所起的作用，对理解对方的程序也有一些帮助。另外CONST在其他编程语言中也有出现，如C++、PHP5、C#.net、HC08 C。

DMA 在实现DMA传输时，是由DMA控制器直接掌管总线，因此，存在着一个总线控制权转移问题。即DMA传输前，CPU要把总线控制权交给DMA控制器，而在结束DMA传输后，DMA控制器应立即把总线控制权再交回给CPU。一个完整的DMA传输过程必须经过DMA请求、DMA响应、DMA传输、DMA结束4个步骤。 */ 8 O- a' U) n0 p5 C3 I$ c

在键值寄存器(IWDG_KR)中写入 0xCCCC，开始启用独立看门狗；此时计数器开始从其复 位值 0xFFF 递减计数。当计数器计数到末尾 0x000 时，会产生一个复位信号(IWDG_RESET)。 无论何时，只要键寄存器 IWDG_KR 中被写入 0xAAAA， IWDG_RLR 中的值就会被重新加载 到计数器中从而避免产生看门狗复位 。 IWDG_PR 和 IWDG_RLR 寄存器具有写保护功能。要修改这两个寄存器的值，必须先向 IWDG_KR 寄存器中写入 0x5555。将其他值写入这个寄存器将会打乱操作顺序，寄存器将重新 被保护。重装载操作(即写入 0xAAAA)也会启动写保护功能。 还有两个寄存器，一个预分频寄存器（IWDG_PR），该寄存器用来设置看门狗时钟的分频 系数。另一个重装载寄存器。该寄存器用来保存重装载到计数器中的值。该寄存器也是一个 32 位寄存器，但是只有低 12 位是有效的。 只要对以上三个寄存器进行相应的设置，我们就可以启动 STM32 的独立看门狗。 那么这个就是看门狗定义的 结构体类型。 typedef struct
