先用文本編輯器打開該網(wǎng)頁寒亥，看看控制LED等開關(guān)的代碼是什么，全部代碼如下：

其中關(guān)鍵代碼是：
<form method="get" action="/leds.cgi">
<input value="1" name="led" type="checkbox">LED1<br>
<input value="2" name="led" type="checkbox">LED2<br>
<input value="3" name="led" type="checkbox">LED3<br>
<input value="4" name="led" type="checkbox">LED4

一些疑問
- 開發(fā)板中的網(wǎng)頁運(yùn)行在什么之上北戏，開發(fā)板上都有哪些目錄和文件（至少有個(gè)/www/leds.cgi）强缘，如何查看？
- 關(guān)于下面一段話采呐，standalone是什么概念？
Applications running in standalone (without an RTOS) or running with FreeRTOS operating system
