【程序】Marvell 88W8801 WiFi模块连接路由器，并使用lwip2.0.3建立http服务器（20180729版）

该程序是旧版本！最新版本为20220213版：
https://blog.csdn/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，请务必连接！
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！

程序支持连接无密码的热点以及WPA-PSK和WPA2-PSK认证类型的热点，加密方式支持TKIP和AES。
程序暂不支持WEP加密方式，也不支持Ad-Hoc模式，或创建AP热点（路由器热点）。

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

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

本程序由STM32F103RE单片机无操作系统驱动88W8686模块的程序（20180706版）修改而来。主要改动如下：
1. 修改了寄存器的定义。88W8801的寄存器位置与88W8686不一样
2. 修改了固件下载函数WiFi_DownloadFirmware。88W8686有两个固件，先下载helper_sd后下载sd8686，但88W8801只有一个固件：sd8801_uapsta
3. 修改了WiFi_LowLevel_GetBlockNum函数。该函数不再返回0，因为88W8801仅在下载固件时才能使用多字节模式（高速模式下也行）
   提示：从CIS信息中可以看出，88W8801最大允许的块大小为512，所以在下载固件前就用WiFi_LowLevel_SetBlockSize函数把Function 1的块大小设为512，之后保持不动，也是可以的
4. 修改了WiFi_LowLevel_GPIOInit函数。88W8801模组的复位引脚是PDN，低电平有效，不需要像88W8686那样在电源引脚上外接三极管辅助复位
5. 88W8686只有一个数据通道，但88W8801有11个数据通道，所以wifi_tx_packet全局变量变成了一个数组，修改了数据帧的发送、接收和确认代码
6. 88W8801的固件自带EAPOL认证功能，所以程序中去掉了处理EAPOL认证代码。WiFi_KeyMaterial函数也做了修改，仅支持获取密钥，不支持设置密钥
7. 88W8801的数据帧描述符和88W8686不一样。命令头部的seq_num变成了8字节，多了一个bss字段。事件头部event_id变成了16字节，多了bss_num和bss_type字段。有些事件的结构中不包含mac_address等字段。
8. 88W8686支持Ad-hoc模式，但88W8801不支持。笔者暂时不确定88W8782是否支持Ad-hoc，所以把Ad-hoc代码保留在了程序中，模块在不支持的情况下会提示Ad-hoc mode is unsupported
9. 新增事件：Event 23（WWM事件）和Event 43（认证成功事件），WiFi_AuthenticationCompleteHandler函数在43号事件产生时调用

10. 修改了WiFi_LowLevel_VerifyFirmware函数。函数会检查WIFI_FIRMWARE_SIZE的值是否有效，避免出现Hard Error错误
    flash saver程序也会检查芯片Flash总大小是否合法
11. 添加了RTC时钟类型检测代码。当当前运行的RTC时钟与宏定义RTC_USELSI不符时自动重置RTC
12. 把程序中用netif_set_up/down的地方都改成了netif_set_link_up/down。用netif_is_link_up函数可判断WiFi是否已连上网
    在low_level_init函数中去掉了默认的NETIF_FLAG_LINK_UP选项, 因为无线网卡默认是未连接状态
13. 修改了wifi_test中的测试代码，测试DNS时会检查tcp_connect函数的返回值，连接建立成功后不是立即关闭连接，而是发送一个简单的HTTP请求接收网页数据，最后（被动）等待连接关闭

【勘误】

2018年8月1日：测速器上位机程序中，network.c里面的network_find_ip函数中，freeaddrinfo函数调用的位置不对，因为传入的参数info始终为NULL，应该传入的是getaddrinfo从第四个参数返回的值。正确的代码为（【程序】Windows下根据计算机名获取IP地址的C语言程序_ZLK1214的专栏-CSDN博客）中的方法二的代码

【模块连线】

模块底板的PCB文件（可以自己打一个PCB出来）：8782模块资料.zip_免费高速下载|百度网盘-分享无限制

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。
