【程式】STM32F407VE微控制器驅動Marvell 88W8801 WiFi模組的程式（20181010版）

阿新 • • 發佈：2018-12-14

本程式所用的微控制器型號為：STM32F407VE
PD14埠為復位引腳（PDN），請務必連線！
晶振用的是8MHz，請注意檢查自己的開發板，看看晶振是不是8MHz。如果是25MHz，請修改system_stm32f4xx.c檔案！

程式支援連線無密碼的熱點以及WEP、WPA-PSK和WPA2-PSK認證型別的熱點，加密方式支援TKIP和AES。WEP加密型別僅支援新增一個金鑰。
程式暫不支援建立AP熱點（路由器熱點）。
88W8801不支援Ad-Hoc點對點模式, 請不要使用程式中與Ad-Hoc有關的函式。

用Keil5編寫程式的時候，工程資料夾路徑最好不要出現中文哦！不然程式碼提示可能會有問題
wifi_88w8801是主程式，直接開啟下載執行即可。該程式裸機執行，不帶作業系統，執行最新的lwip-2.0.3協議棧

sd8801_uapsta.c是WiFi模組的韌體，上電執行時必須由單片機發送給WiFi模組執行
該韌體資料非常大，為了節約程式編譯下載的時間，可以執行flash_saver程式將這些資料儲存到Flash固定區域
然後根據串列埠提示，修改WiFi.h中WIFI_FIRMWAREAREA_ADDR的值（取消註釋）
這樣就可以移除sd8801_uapsta.c檔案，大幅度降低程式燒寫時間了

【模組連線】

D0~D3接PC8~11，CMD接PD2，CLK接PC12，RESET懸空，PDN接PD14。GND接電源負極，VCC直接接到電源正極。

【Keil5工程截圖】

【筆者所用的開發板和WiFi模組】

在筆者所用的開發板上，Wi-Fi模組的VCC不是直接接到電源上的，而是串聯了一個場效電晶體，當PA15為低電平時Wi-Fi模組通電。

【程式執行截圖】

1. 串列埠輸出

2. ping IP地址和計算機名

3. IE瀏覽器通過計算機名訪問板上的HTTP伺服器

4. 路由器管理頁面中看到的DHCP客戶端列表

5. TCP和UDP資料傳送速度測試結果
