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

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

smart_config.h
#ifndef APP_INCLUDE_SMART_CONFIG_H_ #define APP_INCLUDE_SMART_CONFIG_H_ void smartconfig_task(void *pvParameters); #endif /* APP_INCLUDE_SMART_CONFIG_H_ */
然后主函数
wifi_station_disconnect(); wifi_set_event_handler_cb(wifi_event_monitor_handle_event_cb); wifi_set_opmode(STATION_MODE); smartconfig_set_type(SC_TYPE_ESPTOUCH_AIRKISS);//SmartConfig + AirKiss xTaskCreate(smartconfig_task, "smartconfig_task", 256, NULL, 2, NULL);
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
static void kprintn (void (*)(const char), uint32_t, int, int, char); static void kdoprnt (void (*)(const char), const char *, va_list); void dbg_printf(const char *fmt, ...) { va_list ap; va_start(ap, fmt); kdoprnt(uart0_write_char, fmt, ap); va_end(ap); } void dbg_vprintf(const char *fmt, va_list ap) { kdoprnt(uart0_write_char, fmt, ap); } void kdoprnt(void (*put)(const char), const char *fmt, va_list ap) { register char *p; register int ch, n; unsigned long ul; int lflag, set; char zwidth; char width; for (;;) { while ((ch = *fmt++) != '%') { if (ch == ' ') return; put(ch); } lflag = 0; width = 0; zwidth = ' '; reswitch: switch (ch = *fmt++) { case ' ': /* XXX print the last format character? */ return; case 'l': lflag = 1; goto reswitch; case 'c': ch = va_arg(ap, int); put(ch & 0x7f); break; case 's': p = va_arg(ap, char *); if (p == 0) { p = "<null>"; } while ((ch = *p++)) put(ch); break; case 'd': ul = lflag ? va_arg(ap, long) : va_arg(ap, int); if ((long)ul < 0) { put('-'); ul = -(long)ul; } kprintn(put, ul, 10, width, zwidth); break; case 'o': ul = lflag ? va_arg(ap, uint32_t) : va_arg(ap, uint32_t); kprintn(put, ul, 8, width, zwidth); break; case 'u': ul = lflag ? va_arg(ap, uint32_t) : va_arg(ap, uint32_t); kprintn(put, ul, 10, width, zwidth); break; case 'x': ul = lflag ? va_arg(ap, uint32_t) : va_arg(ap, uint32_t); kprintn(put, ul, 16, width, zwidth); break; default: if (ch >= '0' && ch <= '9') { if (ch == '0' && width == 0 && zwidth == ' ') { zwidth = '0'; } else { width = width * 10 + ch - '0'; } goto reswitch; } put('%'); if (lflag) put('l'); put(ch); } } va_end(ap); } static void kprintn(void (*put)(const char), uint32_t ul, int base, int width, char padchar) { /* hold a long in base 8 */ char *p, buf[(sizeof(long) * 8 / 3) + 2]; 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
