该程序是旧版本！最新版本为版：
/ZLK1214/article/details/122915474
本程序所用的单片机型号为：STM32F103ZE
可以用STM32F103RE或STM32F103RD，但是STM32F103RC不行！
PB12端口为复位引脚（PDN），请务必连接！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文件，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AP热点（路由器热点）。需要创建AP热点代码的读者请私下联系QQ970349094。
88W8801不支持Ad-Hoc点对点模式, 请不要使用程序中与Ad-Hoc有关的函数。
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，运行的是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（要求芯片为STM32F103xE或以上）
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
移植到STM32F407VE单片机上的程序（1010版）：/ZLK1214/article/details/82995164
此版本修复了上一个版本（0729版）存在的一些问题，主要更新如下：
1. 收到命令回应时，如果result字段不为0，则调用回调函数时，传入的参数status为WIFI_STATUS_FAIL或WIFI_STATUS_UNSUPPORTED，不再是WIFI_STATUS_OK
当命令回应或数据帧确认超时时，status为WIFI_STATUS_NORESP（这个没变）
2. 数据帧确认超时时，串口会输出提示（WIFI_DISPLAY_RESPTIME选项启用的情况下）
3. 添加了连接WEP热点的支持（单WEP密钥），并能够显示已添加的密钥（串口发送k）
4. 修复了当关联热点成功但尚未认证成功时，串口发送R可以重连热点导致系统故障的bug
5. 添加了WiFi_EventProcess函数处理WiFi事件，修复了WiFi掉线后WiFi_Deauthenticate仍能执行成功的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. 修复了测速上位机程序中freeaddrinfo释放不了内存的问题
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（提取码：rn8h），然后把WiFi.h中的数据发送通道数WIFI_DATAPORTS_TX_NUM由11改为15。

顶层：
上面字都写错了，不是W8287，是W8801才对，自己改过来吧。。。
底层：
其中，7脚RST接的是中间14脚模组的PDN引脚，低电平有效。
