该程序是旧版本！最新版本为20200208版：
https://blog.csdn.net/ZLK1214/article/details/104229202
本程序所用的单片机型号为：STM32F103VE或STM32F407VE
复位引脚（PDN）应连接到STM32F1的PA2引脚或STM32F4的PD14引脚。不连接PDN引脚将导致固件无法下载！如果模块上有PDN和RESET两个引脚，只需要连接PDN引脚。因为模块上的RESET引脚是悬空的，根本就没有连到芯片上
晶振用的是8MHz，请注意检查自己的开发板，看看晶振是不是8MHz。如果是12MHz，请修改system_stm32f10x.c或system_stm32f4xx.c文件！在F1单片机上是把PLL的倍频系数由9改成6（8×9=12×6），并在工程属性中定义HSE_VALUE=12000000
程序支持连接无密码的热点以及WEP、WPA-PSK和WPA2-PSK认证类型的热点，加密方式支持TKIP和AES。WEP加密类型仅支持添加一个密钥
程序暂不支持创建有密码的AP热点（路由器热点）
88W8801不支持Ad-Hoc点对点模式
用Keil5编写程序的时候，工程文件夹路径最好不要出现中文哦！不然代码提示可能会有问题
wifi_88w8801是主程序，直接打开下载运行即可。该程序裸机运行，不带操作系统，运行最新的lwip-2.0.3协议栈
现在lwip2.1版本已经发布了。该版本的lwip压缩包（lwip-2.1.0.zip）中的src/netif文件夹下没有ethernetif.c了，那个文件是被移动到contrib-2.1.0.zip的examples/ethernetif文件夹下去了
sd8801_uapsta.c是WiFi模块的固件，上电运行时必须由单片机发送给WiFi模块运行
该固件数据非常大，为了节约程序编译下载的时间，可以运行flash_saver程序将这些数据保存到Flash固定区域（要求芯片Flash容量至少为384KB）
然后根据串口提示，修改WiFi.h中WIFI_FIRMWAREAREA_ADDR的值（取消注释）
这样就可以移除sd8801_uapsta.c文件，大幅度降低程序烧写时间了
本程序也支持88W8782芯片，但需要将固件sd8801_uapsta.c替换成8782的内容，然后把WiFi.h中的数据发送通道数WIFI_DATAPORTS_TX_NUM由11改为15
Keil5工程下载地址：
【标准库版本】https://pan.baidu.com/s/1HupWIIN_eTU-QvbTbQN66A（提取码：t123）
【HAL库版本】https://pan.baidu.com/s/1myogwFS687nCnsPEzU9ySQ（2019年12月12日发布）
HAL库版本的Keil工程不是由STM32CubeMX创建的，而是手工建立的。其代码风格和标准库版本是一致的。
2019年12月12日发布的程序中还包含了SPI方式驱动88W8801的程序，包括标准库版本和HAL库版本。使用时直接替换WiFi_LowLevel.c即可。
【勘误】
2020年1月10日：在某些环境下，扫描热点时会出现Hard Error的错误。这是因为WiFi_Scan_Callback函数里面没有正确处理IEEE TLV导致了缓冲区溢出。解决方法是在如图所示的位置（while (ie_size > 0)下方）添加以下代码：
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也有同样的问题，可以用同样的方法修复。
2020年2月3日：STM32F4标准库程序里面WiFi_LowLevel.c的读写函数中，如果开启了标准库的assert_failed检验，则会因为dma.DMA_BufferSize为0而出错。SDIO的DMA用不到这个成员，所以可以填写任何非0值，将0改为1即可解决问题。
此版本修复了上一个版本（20180807版和20181010版）存在的一些问题，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模式的代码
3. 去掉了断开连接的回调函数stop_callback里面status参数的无效判断
4. 添加了检查PDN引脚是否正确连接的功能
5. F4单片机上自动开启SDIO所需的PLL倍频器
6. 可以根据指定的SDIO时钟频率自动计算分频系数
7. 添加了输出字符串格式的dump函数，并在TCP接收数据的案例中使用
8. 添加了保存在单片机Flash固定区域中的固件内容已被破坏的详细printf输出
9. WriteData函数允许禁用缓冲区大小检查
10. 优化了命令帧缓冲区结构体，合并了WiFi.c中以Ex结尾的扩展函数
11. 优化了数据帧缓冲区结构体，去掉了数据帧的回调功能
12. 创建了ethernetif.h，将ethernetif结构体和相关的函数声明在里面
13. 按端口顺序接收数据帧
14. 解决了第一次连接热点失败的bug
15. WiFi_EventHandler中用宏名表示事件号
16. 把main函数中判断SDIO中断是否发生的代码放到了LowLevel层中
17. 命令、数据和事件增加了bss字段的支持，给出了创建无密码AP的示例代码
18. 不再使用dhcp->offered_xxx，改成显示netif里面的IP地址
19. 修复了WiFi_EventHandler函数中认证失败时无法自动重连的bug
20. 数据发送速度测速器使用setsockopt设置了recv超时时间，单片机端使用tcp_shutdown函数通知主机停止接收数据
21. 收发数据时改成等待DATAEND位而不是TXACT或RXACT位, 增加了超时判定
22. WriteData和ReadData失败时重新读写，增加了固件下载出错时重传的功能，增加了address increment选项，以及是否允许使用多字节（Stream）模式的选项
23. 将网卡输入函数由ethernet_input改为通用的netif_input
24. 给头文件加上了#ifndef防重复包含的宏定义
25. low_level_output发送数据帧前检查网络连接是否是连通的
26. 添加了显示TCP报文字段详细信息的功能（tcpdump）
27. wifi_test中添加了错误处理代码

【笔者所用的开发板和WiFi模块】
STM32F103VE开发板（外部5V电源供电）：
STM32F407VE开发板（电脑USB口供电）：
带底板的88W8801 WiFi模块：
如果用的开发板上面带有SD卡槽，即使里面不插内存卡，运行程序时，下载固件后或获取MAC地址后一直出现CRC错误和data timeout错误，可以采取下面的措施：
（1）把SDIO模式由4位数据线模式改为1位模式，只接SDIO_D0（PC8）和SDIO_D1（PC9，作为SDIO中断引脚），不接SDIO_D2~3（PC10~11） 。修改WiFi_LowLevel_SDIOInit函数，将下面两句话注释掉，只保留SDIO_Init
/* SDIO外设的总线宽度设为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);
改为1位数据模式后，笔者上面的黑色带卡槽开发板的问题已经解决（用电脑USB口供电，串口用的是USB转TTL模块）。
（2）如果还是不行，就降低SDIO的时钟频率。打开WiFi.h，将WIFI_CLOCK_FREQ改小。如100万（1MHz），50万（500kHz），或者10万（100kHz），可以设为0（使用最低频率，也就是最高分频系数）
不过SD卡槽里面不要插内存卡。尽管插了内存卡进去，Wi-Fi模块还是可以照常使用，但是SD卡是没法用的，SD卡正常的初始化命令序列（如CMD2、CMD3）是无法成功执行的。
虽然SDIO标准规定可以总线上可以接多张SD卡，但STM32单片机的SDIO接口只支持接一张卡，STM32F103的芯片手册Datasheet（不是参考手册）中有声明：
The current version supports only one SD/SDIO/MMC4.2 card at any one time and a stack of MMC4.1 or previous.
如果想要同时使用WiFi模块和SD内存卡，建议SD内存卡采用SPI总线通信。
【程序运行截图】
1. 串口输出
2. ping IP地址和计算机名
3. 访问http服务器
4. 将固件烧写到单片机Flash固定区域的程序（用于节约主程序烧写时间）
