【程式】Marvell 88W8801 WiFi模組連線路由器，並使用lwip2.0.3建立http伺服器（20180807版）
阿新 • • 發佈：2019-01-10
本程式所用的微控制器型號為：STM32F103ZE
可以用STM32F103RE或STM32F103RD，但是STM32F103RC不行！
PB12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12MHz，請修改system_stm32f10x.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（要求晶片為STM32F103xE或以上）
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
此版本修復了上一個版本（20180729版）存在的一些問題，主要更新如下：
1. 收到命令迴應時，如果result欄位不為0，則呼叫回撥函式時，傳入的引數status為WIFI_STATUS_FAIL或WIFI_STATUS_UNSUPPORTED，不再是WIFI_STATUS_OK
當命令迴應或資料幀確認超時時，status為WIFI_STATUS_NORESP（這個沒變）
2. 資料幀確認超時時，串列埠會輸出提示（WIFI_DISPLAY_RESPTIME選項啟用的情況下）
3. 添加了連線WEP熱點的支援（單WEP金鑰），並能夠顯示已新增的金鑰（串列埠傳送k）
4. 修復了當關聯熱點成功但尚未認證成功時，串列埠傳送R可以重連熱點導致系統故障的bug
5. 添加了WiFi_EventProcess函式處理WiFi事件，修復了WiFi掉線後WiFi_Deauthenticate仍能執行成功的bug（wifi_ssid_info未清零）
6. 把wifi_test中的IP4_*全部改成了IP_*，如ip4_addr_t改成了ip_addr_t
7. 修復了測速上位機程式中freeaddrinfo釋放不了記憶體的問題
【模組連線】
頂層：
上面字都寫錯了，不是W8287，是W8801才對，自己改過來吧。。。
底層：
其中，7腳RST接的是中間14腳模組的PDN引腳，低電平有效。

【筆者所用的開發板和WiFi模組】
【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
