1.在user_init(void)初始化好串口基本信息進(jìn)入ESP8266_STA_Init();設(shè)置STA基本信息，利用軟件定時(shí)器連接wifi
- void ICACHE_FLASH_ATTR user_init(void)
- {
- uart_init(115200,115200);
- os_delay_us(1000);
- os_printf("\r\n==========================================\r\n");
- os_printf("\r\n ProjectName: %s\r\n",ProjectName);
- os_printf("\r\n==========================================\r\n");
- ESP8266_STA_Init();
- OS_Timer_1_Init_JX(1000,1);
- os_printf("===================user init is over====================");
- }
- void ICACHE_FLASH_ATTR ESP8266_NetCon_Init()
- {
- ST_NetCon.type = ESPCONN_UDP; //設(shè)置通信協(xié)議為UDP
- ST_NetCon.proto.udp = (esp_udp *)os_zalloc(sizeof(esp_udp)); // 開(kāi)辟內(nèi)存
- //此處設(shè)置本地端口號(hào)以及遠(yuǎn)程設(shè)備的IP地址和端口號(hào)，因?yàn)镋SP8266設(shè)置為客戶端
- ST_NetCon.proto.udp->local_port = 8266;
- ST_NetCon.proto.udp->remote_port = 8888;
- ST_NetCon.proto.udp->remote_ip[0]=192;
- ST_NetCon.proto.udp->remote_ip[1]=168;
- ST_NetCon.proto.udp->remote_ip[2]=1;
- ST_NetCon.proto.udp->remote_ip[3]=8;
- Uart_arg = &ST_NetCon;//把遠(yuǎn)程設(shè)備的IP地址和端口號(hào)地址賦值給Uart_arg，方便在串口函數(shù)中使用
- //注冊(cè)回調(diào)函數(shù)
- espconn_regist_recvcb(&ST_NetCon,ESP8266_WIFI_Recv_cb);
- espconn_regist_sentcb(&ST_NetCon,ESP8266_WIFI_Sent_cb);
- //初始化UDP通信
- espconn_create(&ST_NetCon);
- //客戶端主動(dòng)向服務(wù)器發(fā)送數(shù)據(jù)
- espconn_send(&ST_NetCon,"Hello,I am ESP8266\n",os_strlen("Hello,I am ESP8266\n"));
- }
4.在uart.c文件下定義結(jié)構(gòu)體struct espconn *Uart_arg;并在uart.h文件下定義好extern struct espconn *Uart_arg;
5.在uart.c文件下的uart_recvTask(os_event_t *events)函數(shù)中編寫(xiě)串口接收數(shù)據(jù)后的操作。()
- LOCAL void ICACHE_FLASH_ATTR ///////
- uart_recvTask(os_event_t *events)
- {
- ....... //
- //從串口接收數(shù)據(jù)后在此編寫(xiě)你要操作的程序
- {
- os_printf("\nESP8266 Uart0 Recieve Word:\n");
- uart0_sendStr(Uart0_Buffer); //串口打印從串口接收到的數(shù)據(jù)
- espconn_send(Uart_arg,Uart0_Buffer,os_strlen(Uart0_Buffer)); //發(fā)送數(shù)據(jù)給遠(yuǎn)端設(shè)備
- .........
- }
- }
