SmartConfig/Airkiss 配網需要APP/微信公眾號,這節大家先使用我做好的APP/微信公眾號
APP下載:
https://www.cnblogs.com/yangfengwu/p/11249674.html
微信公眾號: 掃描這個二維碼關注我的公眾號
其余的步驟等寫完8266的配網程序,在下面演示.
如果想自己實現微信綁定可以看↓ (注:配置過程和源碼全部是公開的,大家看文章即可實現)
如果你已經有做網頁的經驗了,可以直接
如果你沒有做過網頁,你需要先看
然后需要把微信小程序篇的所有章節從頭到尾看一遍
現在開始寫WIFI的配網程序
其實官方給了例子
咱把例子寫個單獨的.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_ */
然后主函數
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);
現在是模塊一啟動就進去配網...
編譯出錯
加上 -lairkiss\
下載進去,咱先測試下
SmartConfig:
下載完WIFI的程序,復位下WIFI
這個APP是我做的一個面向開發使用的,該APP源碼獲取方式: https://www.cnblogs.com/yangfengwu/p/11249674.html
AirKiss : 關注我的這個測試用的公眾號
復位WIFI模塊
好,現在優化下
按下固件按鈕(GPIO0)大約3S, 讓GPIO2那個燈快閃,進入配網模式,然后60S超時檢測.還有就是不讓WIFI打印官方內部寫的東西(打印的東西太多了...)

然后還有兩個地方,無論是SmartConfig 還是 Airkiss 配網,配完網以后都重啟下
好,測試
按下大約3S,指示燈快閃
軟件就不截圖了,按照上面的步驟操作
SmartConfig 打印的信息
Airkiss 打印的信息

好現在,不讓調試信息通過usart0打印
這個設置以后 printf就不會通過uart0打印了 ,會用uart1(GPIO2) 打印......
這個不強求哈!!!大家不修改也可以,我只是不希望讓系統一直打印各種信息,我擔心后面和單片機做通信的時候會出問題!
當然大家也可以直接用 USART_SendData(uint8 uart, uint8 TxChar) 發送數據,我只不過是封裝成可以用printf形式
還記得咱前面的某一節咱自己寫的printf不,不過呢,咱直接用lua源碼里面寫的,因為我寫的那個太占內存.....
把這部分代碼放到 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 == '\0') return; put(ch); } lflag = 0; width = 0; zwidth = ' '; reswitch: switch (ch = *fmt++) { case '\0': /* 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); }
需要修改一個地方
然后全部替換為
就可以實現printf的方式了
如果大家嫌麻煩也可以不用復制粘貼那部分
直接用 uart0_write_char()
現在只是模塊一開始啟動的時候打印些自身的信息,后期的都是打印的咱自己寫的
如果大家不希望打印信號強度
可以
好了,又完成一節
