优秀不够,你是否无可替代

知识从未如此性感。 烂程序员关心的是代码,好程序员关心的是数据结构和它们之间的关系 --QQ群: 607064330 --本人QQ:946029359 --淘宝 https://shop411638453.taobao.com/ 博客园所有资料源码链接 https://www.cnblogs.com/yangfengwu/ 看博客阅读说明

26-ESP8266 SDK开发基础入门篇--编写WIFI模块 SmartConfig/Airkiss 一键配网

https://www.cnblogs.com/yangfengwu/p/11427504.html

 

SmartConfig/Airkiss 配网需要APP/微信公众号,这节大家先使用我做好的APP/微信公众号

APP下载: 

https://www.cnblogs.com/yangfengwu/p/11249674.html

 

 

 微信公众号: 扫描这个二维码关注我的公众号

    

其余的步骤等写完8266的配网程序,在下面演示.

 

 如果想自己实现微信绑定可以看↓ (注:配置过程和源码全部是公开的,大家看文章即可实现)

 

如果你已经有做网页的经验了,可以直接

 

 

 

 如果你没有做过网页,你需要先看

  

 

 

然后需要把微信小程序篇的所有章节从头到尾看一遍

 

 

现在开始写WIFI的配网程序

其实官方给了例子

 

 

 咱把例子写个单独的.C和.H文件,方便咱后期使用

 现在是模块一启动就进去配网...

编译出错

加上    -lairkiss\

 

下载进去,咱先测试下

 

SmartConfig:

    

 

 下载完WIFI的程序,复位下WIFI

 

                                                                                                                      

      

 

 这个APP是我做的一个面向开发使用的,该APP源码获取方式:  https://www.cnblogs.com/yangfengwu/p/11249674.html

 

 

 AirKiss :  关注我的这个测试用的公众号

复位WIFI模块

    

 

 

 

 好,现在优化下

按下固件按钮(GPIO0)大约3S, 让GPIO2那个灯快闪,进入配网模式,然后60S超时检测.还有就是不让WIFI打印官方内部写的东西(打印的东西太多了...)

然后还有两个地方,无论是SmartConfig 还是 Airkiss 配网,配完网以后都重启下

 

 

 

 

 

 好,测试

按下大约3S,指示灯快闪

 

 软件就不截图了,按照上面的步骤操作

好现在,不让调试信息通过usart0打印

 

 

 

 这个设置以后  printf就不会通过uart0打印了 ,会用uart1(GPIO2) 打印......

 这个不强求哈!!!大家不修改也可以,我只是不希望让系统一直打印各种信息,我担心后面和单片机做通信的时候会出问题!

当然大家也可以直接用  USART_SendData(uint8 uart, uint8 TxChar)  发送数据,我只不过是封装成可以用printf形式

 

还记得咱前面的某一节咱自己写的printf不,不过呢,咱直接用lua源码里面写的,因为我写的那个太占内存.....

 

 

 

 

 

 

把这部分代码放到 uart.c 里面

}

{
    kdoprnt(uart0_write_char, fmt, ap);
}

                kprintn(put, ul, 8, width, zwidth);
                break;
            case 'u':

                    va_arg(ap, uint32_t) : va_arg(ap, uint32_t);
                kprintn(put, ul, 10, width, zwidth);
                break;

                   else
                   {
                      width = width * 10 + ch - '0';
                   }

static void kprintn(void (*put)(const char), uint32_t ul, int base, int width, char padchar)

    p = buf;
    do {
        *p++ = "0123456789abcdef"[ul % base];
    } while (ul /= base);

        while (p - buf < width--) {
          put(padchar);
        }

    do {
        put(*--p);
    } while (p > buf);
}

需要修改一个地方

 

 

 

 

 

 

 

然后全部替换为

 

 

就可以实现printf的方式了

 

如果大家嫌麻烦也可以不用复制粘贴那部分

直接用  uart0_write_char()  

 

现在只是模块一开始启动的时候打印些自身的信息,后期的都是打印的咱自己写的

 

 

 

如果大家不希望打印信号强度

 

 

 

 

 

 

可以

 

 

 

 

好了,又完成一节
