介紹

Keil作為使用廣泛的一款嵌入式開發IDE，大多數的工程師只用到了編譯和仿真功能，其實只需要一些編程小技巧就可以通過Keil將代碼的一些配置可視化。

本篇將要介紹的是Keil的一項功能叫做 Configuration Wizard (配置向導)，這是內嵌在Keil編輯器中的一項功能，按照既定規則在代碼中標記后則可以產生配置可視化的效果（如下圖所示），由于是以注釋的形式進行標記，所以并不會實際影響代碼的移植編譯以及正常功能。

配置向導語法

當編輯器檢測到代碼中存在有

//***  Use Configuration Wizard in Context Menu >> >***

并且以如下代碼結束

//***< > >***

那么Keil的編輯器則會識別并解析注釋內容生成對應的圖形化配置界面，編碼的規則如下所示

范例代碼

如下是介紹章節顯示圖對應的幫助文檔提供的范例代碼，可以參考實際編碼操作一下
