我可以回答这个问题。以下是一个示例代码:
#include <reg52.h>
#include <stdio.h>
#include <string.h>
#define BAUDRATE 9600
#define ESP8266_SSID "your_SSID"
#define ESP8266_PASSWORD "your_password"
#define ALIYUN_PRODUCT_KEY "your_product_key"
#define ALIYUN_DEVICE_NAME "your_device_name"
#define ALIYUN_DEVICE_SECRET "your_device_secret"
sbit ESP8266_RST = P1^0;
sbit ESP8266_CH_PD = P1^1;
void init_serial() {
TMOD = 0x20;
TH1 = 256 - (11059200 / 12 / BAUDRATE);
TL1 = TH1;
TR1 = 1;
SM0 = 0;
SM1 = 1;
REN = 1;
}
void send_byte(unsigned char byte) {
SBUF = byte;
while (!TI);
TI = 0;
}
void send_string(char *str) {
while (*str) {
send_byte(*str++);
}
}
void esp8266_send_command(char *cmd) {
send_string(cmd);
send_string("\r\n");
}
void esp8266_wait_for_response(char *response) {
char buffer[128];
int i = 0;
while (1) {
if (RI) {
buffer[i++] = SBUF;
RI = 0;
if (i >= strlen(response)) {
buffer[i] = '\0';
if (strcmp(buffer + i - strlen(response), response) == 0) {
break;
}
}
}
}
}
void esp8266_reset() {
ESP8266_RST = 0;
ESP8266_CH_PD = 0;
delay(100);
ESP8266_RST = 1;
ESP8266_CH_PD = 1;
delay(1000);
}
void esp8266_connect_wifi() {
esp8266_send_command("AT+CWJAP=\"" ESP8266_SSID "\",\"" ESP8266_PASSWORD "\"");
esp8266_wait_for_response("OK");
}
void esp8266_connect_aliyun() {
char buffer[128];
sprintf(buffer, "AT+IOTCID=\"%s.%s\"", ALIYUN_PRODUCT_KEY, ALIYUN_DEVICE_NAME);
esp8266_send_command(buffer);
esp8266_wait_for_response("OK");

esp8266_wait_for_response("OK");
esp8266_send_command("AT+IOTCONNECT");
esp8266_wait_for_response("CONNECTED");
}
void main() {
init_serial();
esp8266_reset();
esp8266_connect_wifi();
esp8266_connect_aliyun();
while (1) {
// do something
}
}
