編寫與一個USB裝置驅動程式的方法和其他匯流排驅動方式類似，驅動程式把驅動程式物件註冊到USB子系統中，稍後再使用製造商和裝置標識來判斷是否安裝了硬體。當然，這些製造商和裝置標識需要我們編寫進USB 驅動程式中。 USB 驅動程式依然遵循裝置模型 —— 匯流排、裝置、驅動
嵌入式Linux開發——(十五)移植YAFFS檔案系統
一、移植YAFFS檔案系統 1）YAFFS檔案系統的介紹 ①YAFFS（yet another flash file system）是一種類似於JFFS / JFFS2，專門為NAND Flash設計的嵌入式檔案系統，適用於大 &nbs
嵌入式Linux開發——(十四)移植Linux核心
基於Linux2.6.22.6 1、相關常識 ①VERSION = 2 PATCHLEVEL=6 主版本號，穩定版本用偶數來表示，每隔2~~3年出現一個穩定版 &nbs
Linux USB裝置驅動程式設計 和 USB下載線驅動設計
Linux USB裝置驅動程式設計 和 USB下載線驅動設計 USB裝置驅動模型 USB裝置包括配置(configuration)、介面（interface）和端點(endpoint)，一個USB裝置驅動程式對應一個USB介面，而非整個USB裝置。 在Lin
Linux usb 裝置驅動 (1)
在初始化了一些資源之後，可以看到第一個關鍵的函式呼叫——interface_to_usbdev。他通過一個usb_interface來得到該介面所在裝置的裝置描述結構。本來，要得到一個usb_device只要用interface_to_usbdev就夠了，但因為要增加對該usb_device的引用計數，我們

WIFI驅動移植--udhcpc獲取IP
在使用wpa工具連線WIFI的時候，一般採用DHCP方式自動獲取裝置ip。在執行完udhcpc命令後，發現獲取到了IP，但是ifconfig一看，還是沒有IP資訊。在獲取IP後需要配置指令碼設定ip。本文使用udhcpc命令配合配置指令碼，實現自動獲取、設定ip的功能。一、建

Linux 下wifi 驅動開發（三）—— SDIO介面WiFi驅動淺析
SDIO-Wifi模組是基於SDIO介面的符合wifi無線網路標準的嵌入式模組，內建無線網路協議IEEE802.11協議棧以及TCP/IP協議棧，能夠實現使用者主平臺數據通過SDIO口到無線網路之間的轉換。SDIO具有傳輸資料快，相容SD、MMC介面等特點。
嵌入式Linux學習-----u-boot移植
自從大二我就開始接觸微控制器，開始學習51微控制器程式設計及電路圖繪製，經過一段時間的學習，發現嵌入式很有意思。後來在師兄的推薦下，我到圖書館借了韋東山老師寫的《嵌入式Linux應用開發完全手冊》，開始學習嵌入式linux，在虛擬機器安裝Linux，熟悉Linux環境，各種
Linux 下wifi 驅動開發（一）—— WiFi基礎知識解析
一、WiFi相關基礎概念 1、什麼是wifi 我們看一下百度百科是如何定義的： Wi-Fi是一種可以將個人電腦、手持裝置（如pad、手機）等終端以無線方式互相連線的技術，事實上它是一個高頻無線電訊號。[1] 無線保真是一個無線網路通訊技術的品牌
