該程序是舊版本！最新版本爲20200208版：
https://blog.csdn.net/ZLK1214/article/details/104229202
本程序所用的單片機型號爲：STM32F103VE或STM32F407VE
復位引腳（PDN）應連接到STM32F1的PA2引腳或STM32F4的PD14引腳。不連接PDN引腳將導致固件無法下載！如果模塊上有PDN和RESET兩個引腳，只需要連接PDN引腳。因爲模塊上的RESET引腳是懸空的，根本就沒有連到芯片上
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或system_stm32f4xx.c文件！在F1單片機上是把PLL的倍頻係數由9改成6（8×9=12×6），並在工程屬性中定義HSE_VALUE=12000000
程序支持連接無密碼的熱點以及WEP、WPA-PSK和WPA2-PSK認證類型的熱點，加密方式支持TKIP和AES。WEP加密類型僅支持添加一個密鑰
程序暫不支持創建有密碼的AP熱點（路由器熱點）
88W8801不支持Ad-Hoc點對點模式
用Keil5編寫程序的時候，工程文件夾路徑最好不要出現中文哦！不然代碼提示可能會有問題
wifi_88w8801是主程序，直接打開下載運行即可。該程序裸機運行，不帶操作系統，運行最新的lwip-2.0.3協議棧
現在lwip2.1版本已經發布了。該版本的lwip壓縮包（lwip-2.1.0.zip）中的src/netif文件夾下沒有ethernetif.c了，那個文件是被移動到contrib-2.1.0.zip的examples/ethernetif文件夾下去了
sd8801_uapsta.c是WiFi模塊的固件，上電運行時必須由單片機發送給WiFi模塊運行
該固件數據非常大，爲了節約程序編譯下載的時間，可以運行flash_saver程序將這些數據保存到Flash固定區域（要求芯片Flash容量至少爲384KB）
然後根據串口提示，修改WiFi.h中WIFI_FIRMWAREAREA_ADDR的值（取消註釋）
這樣就可以移除sd8801_uapsta.c文件，大幅度降低程序燒寫時間了
本程序也支持88W8782芯片，但需要將固件sd8801_uapsta.c替換成8782的內容，然後把WiFi.h中的數據發送通道數WIFI_DATAPORTS_TX_NUM由11改爲15
Keil5工程下載地址：
【標準庫版本】https://pan.baidu.com/s/1HupWIIN_eTU-QvbTbQN66A（提取碼：t123）
【HAL庫版本】https://pan.baidu.com/s/1myogwFS687nCnsPEzU9ySQ（2019年12月12日發佈）
HAL庫版本的Keil工程不是由STM32CubeMX創建的，而是手工建立的。其代碼風格和標準庫版本是一致的。
2019年12月12日發佈的程序中還包含了SPI方式驅動88W8801的程序，包括標準庫版本和HAL庫版本。使用時直接替換WiFi_LowLevel.c即可。
【勘誤】
2020年1月10日：在某些環境下，掃描熱點時會出現Hard Error的錯誤。這是因爲WiFi_Scan_Callback函數裏面沒有正確處理IEEE TLV導致了緩衝區溢出。解決方法是在如圖所示的位置（while (ie_size > 0)下方）添加以下代碼：
if (TLV_STRUCTLEN(*ie_params) > ie_size)
{
ie_params->header.length = ie_size - sizeof(IEEEHeader);
printf("Found incomplete IEEE TLV! type=%#x\n", ie_params->header.type);
}
WiFi_ScanSSID_Callback也有同樣的問題，可以用同樣的方法修復。
2020年2月3日：STM32F4標準庫程序裏面WiFi_LowLevel.c的讀寫函數中，如果開啓了標準庫的assert_failed檢驗，則會因爲dma.DMA_BufferSize爲0而出錯。SDIO的DMA用不到這個成員，所以可以填寫任何非0值，將0改爲1即可解決問題。
此版本修復了上一個版本（20180807版和20181010版）存在的一些問題，主要更新如下：
1. 工程改成了使用StandardLIB，不使用MicroLIB
2. 移除了88W8801不支持的Ad-Hoc模式的代碼
3. 去掉了斷開連接的回調函數stop_callback裏面status參數的無效判斷
4. 添加了檢查PDN引腳是否正確連接的功能
5. F4單片機上自動開啓SDIO所需的PLL倍頻器
6. 可以根據指定的SDIO時鐘頻率自動計算分頻係數
7. 添加了輸出字符串格式的dump函數，並在TCP接收數據的案例中使用
8. 添加了保存在單片機Flash固定區域中的固件內容已被破壞的詳細printf輸出
9. WriteData函數允許禁用緩衝區大小檢查
10. 優化了命令幀緩衝區結構體，合併了WiFi.c中以Ex結尾的擴展函數
11. 優化了數據幀緩衝區結構體，去掉了數據幀的回調功能
12. 創建了ethernetif.h，將ethernetif結構體和相關的函數聲明在裏面
13. 按端口順序接收數據幀
14. 解決了第一次連接熱點失敗的bug
15. WiFi_EventHandler中用宏名錶示事件號
16. 把main函數中判斷SDIO中斷是否發生的代碼放到了LowLevel層中
17. 命令、數據和事件增加了bss字段的支持，給出了創建無密碼AP的示例代碼
18. 不再使用dhcp->offered_xxx，改成顯示netif裏面的IP地址
19. 修復了WiFi_EventHandler函數中認證失敗時無法自動重連的bug
20. 數據發送速度測速器使用setsockopt設置了recv超時時間，單片機端使用tcp_shutdown函數通知主機停止接收數據
21. 收發數據時改成等待DATAEND位而不是TXACT或RXACT位, 增加了超時判定
22. WriteData和ReadData失敗時重新讀寫，增加了固件下載出錯時重傳的功能，增加了address increment選項，以及是否允許使用多字節（Stream）模式的選項
23. 將網卡輸入函數由ethernet_input改爲通用的netif_input
24. 給頭文件加上了#ifndef防重複包含的宏定義
25. low_level_output發送數據幀前檢查網絡連接是否是連通的
26. 添加了顯示TCP報文字段詳細信息的功能（tcpdump）
27. wifi_test中添加了錯誤處理代碼
【模塊連線】
【Keil5工程截圖】
【筆者所用的開發板和WiFi模塊】
STM32F103VE開發板（外部5V電源供電）：
STM32F407VE開發板（電腦USB口供電）：
帶底板的88W8801 WiFi模塊：
如果用的開發板上面帶有SD卡槽，即使裏面不插內存卡，運行程序時，下載固件後或獲取MAC地址後一直出現CRC錯誤和data timeout錯誤，可以採取下面的措施：
（1）把SDIO模式由4位數據線模式改爲1位模式，只接SDIO_D0（PC8）和SDIO_D1（PC9，作爲SDIO中斷引腳），不接SDIO_D2~3（PC10~11） 。修改WiFi_LowLevel_SDIOInit函數，將下面兩句話註釋掉，只保留SDIO_Init
/* SDIO外設的總線寬度設爲4位 */
//sdio.SDIO_BusWide = SDIO_BusWide_4b;
SDIO_Init(&sdio);
//WiFi_LowLevel_WriteReg(0, SDIO_CCCR_BUSIFCTRL, WiFi_LowLevel_ReadReg(0, SDIO_CCCR_BUSIFCTRL) | SDIO_CCCR_BUSIFCTRL_BUSWID_4Bit);
改爲1位數據模式後，筆者上面的黑色帶卡槽開發板的問題已經解決（用電腦USB口供電，串口用的是USB轉TTL模塊）。
（2）如果還是不行，就降低SDIO的時鐘頻率。打開WiFi.h，將WIFI_CLOCK_FREQ改小。如100萬（1MHz），50萬（500kHz），或者10萬（100kHz），可以設爲0（使用最低頻率，也就是最高分頻係數）
不過SD卡槽裏面不要插內存卡。儘管插了內存卡進去，Wi-Fi模塊還是可以照常使用，但是SD卡是沒法用的，SD卡正常的初始化命令序列（如CMD2、CMD3）是無法成功執行的。
雖然SDIO標準規定可以總線上可以接多張SD卡，但STM32單片機的SDIO接口只支持接一張卡，STM32F103的芯片手冊Datasheet（不是參考手冊）中有聲明：
The current version supports only one SD/SDIO/MMC4.2 card at any one time and a stack of MMC4.1 or previous.
如果想要同時使用WiFi模塊和SD內存卡，建議SD內存卡採用SPI總線通信。
