在keil MDK自带的发动代码有一个优势便是可视化的装备选项，便是Configuration wizard选项，这样就省去了咱们手动输入装备的问题。比方下面关于Memory的规划的Configuration界面：
而在发动代码中的这个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
能够看出，图形化的Configuration句子放在了程序的注释上。详细的语法如下：
| 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. |
别的还有一个重要的一点：假如想要显现Configuration Wizard，
必须在代码文本的头100行之内有如下指令：
//<<
别的在还有一个可选的指令表明Configuration Wizard的完毕：
//<<
