esp8266-01s控制舵机基于51单片机代码

下面是基于51单片机控制ESP8266-01S模块控制舵机的示例代码：

#include <reg52.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#define BAUD_RATE 9600

sbit servo_pin = P1^0;

void delay(unsigned int ms)
{
    unsigned int i, j;
    for(i = ms; i > 0; i--)
    {
        for(j = 110; j > 0; j--);
    }
}

void uart_init()
{
    TMOD &= 0x0F;
    TMOD |= 0x20;
    SCON = 0x50;
    TH1 = 256 - (11059200 / 12 / BAUD_RATE);
    TL1 = TH1;
    TR1 = 1;
    ES = 1;
    EA = 1;
}

void uart_send(char ch)
{
    SBUF = ch;
    while(TI == 0);
    TI = 0;
}

void uart_send_string(char *str)
{
    while(*str != '\0')
    {
        uart_send(*str++);
    }
}

void uart_receive() interrupt 4 using 1
{
    static char buffer[32];
    static uint8_t index = 0;
    char ch = SBUF;
    if(ch == '\r')
    {
        buffer[index] = '\0';
        index = 0;
        if(strcmp(buffer, "open") == 0)
        {
            servo_pin = 1;
            uart_send_string("servo opened\r\n");
        }
        else if(strcmp(buffer, "close") == 0)
        {
            servo_pin = 0;
            uart_send_string("servo closed\r\n");
        }
        else
        {
            uart_send_string("unknown command\r\n");
        }
    }
    else
    {
        buffer[index++] = ch;
    }
}

void main()
{
    uart_init();
    while(1)
    {
        delay(100);
    }
}

这个代码实现了通过串口控制舵机的开关，当接收到“open”时，打开舵机，当接收到“close”时，关闭舵机。详细说明见注释。
