关于keil MDK 的配置文件Configuration Wizard

在keil MDK自带的启动代码有一个优势就是可视化的配置选项，就是Configuration wizard选项，这样就省去了我们手动输入配置的问题。比如下面对于Memory的设计的Configuration界面：

而在启动代码中的这个Configuration的程序为：

// Watchdog Timer Setup

// Watchdog Timer Control Register (WTCON)

// Prescaler Value <0-255>

// Watchdog Timer Enable

// Clock Division Factor

// <0=> 16 <1=> 32 <2=> 64 <3=> 128

// Interrupt Generation Enable

// Reset Enable

//

// Watchdog Timer Data Register (WTDAT)

// Count Reload Value <0-65535>

//

// Watchdog Timer Setup

可以看出，图形化的Configuration语句放在了程序的注释上。具体的语法如下：

Item	Text	Description
	yes	Heading: the following options belong to a group.
	yes	Heading with Enable: the following options belong to a group, which can be enabled via a checkbox.
	yes	Heading with Enable: modifies a specific bit (bit 4, in this example).
or	yes	Heading or Enable end.
	yes	Tool-tip help for previous item.
	yes	Option for bit values which can be set via a checkbox.
	yes	Option with selection or number entry.
	yes	Modify a range of bits (example: bit 4 to 5).
	yes	modify a single bit (example: bit 4).
	yes	Option with ASCII string entry.
	yes	Option with ASCII string entry and a size limit of 10 characters.
Modifier		Description
<0-31>	no	Value range for option fields.
<0-100:10>	no	Value range for option fields with step 10.
<0x40-0x1000:0x10>	no	Value range in hex format and step 10.
<0=>	yes	Value and text for selection.
<#+1> <#-1> <#*8> <#/3>	no	value modification (add, sub, mul, div) before number is merged into field.

另外还有一个重要的一点：如果想要显示Configuration Wizard，

必须在代码文本的头100行之内有如下命令：

//>>

另外在还有一个可选的命令表示Configuration Wizard的结束：
