用keil写出初始化TFT屏幕、初始化ESP8266模块并且连接WiFi网络的c语言代码

以下是基于Keil软件编写的初始化TFT屏幕、初始化ESP8266模块并连接WiFi网络的C语言代码：

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <stdbool.h>
#include "stm32f10x.h"
#include "tftlcd.h"

#define SSID "your_ssid" // WiFi SSID
#define PASSWORD "your_password" // WiFi 密码

// ESP8266 AT指令相关宏定义
#define AT_CMD "AT\r\n"
#define AT_RST "AT+RST\r\n"
#define AT_CWMODE "AT+CWMODE=1\r\n"
#define AT_CWJAP "AT+CWJAP=\"" SSID "\",\"" PASSWORD "\"\r\n"
#define AT_CIFSR "AT+CIFSR\r\n"
#define AT_CIPMUX "AT+CIPMUX=1\r\n"
#define AT_CIPSERVER "AT+CIPSERVER=1,80\r\n"

// ESP8266 状态枚举
typedef enum {
    ESP_OFFLINE,
    ESP_STARTUP,
    ESP_CONNECTED,
    ESP_DISCONNECTED
} esp8266_state_t;

esp8266_state_t esp8266_state = ESP_OFFLINE; // ESP8266 初始状态为离线

// 串口发送单个字符
void USART_SendChar(USART_TypeDef* USARTx, char ch) {
    while (!(USARTx->SR & 0x00000040));
    USARTx->DR = (ch & 0x1FF);
}

// 串口发送字符串
void USART_SendString(USART_TypeDef* USARTx, char* str) {
    while (*str) {
        USART_SendChar(USARTx, *str++);
    }
}

// 串口接收单个字符
char USART_ReceiveChar(USART_TypeDef* USARTx) {
    while (!(USARTx->SR & 0x00000020));
    return (USARTx->DR & 0xff);
}

// 串口接收字符串，以'\r'或'\n'为结束符
void USART_ReceiveString(USART_TypeDef* USARTx, char* str) {
    char ch = 0;
    while (ch != '\r' && ch != '\n') {
        ch = USART_ReceiveChar(USARTx);
        *str++ = ch;
    }
    *(str - 1) = '\0';
}

// 发送 ESP8266 AT 指令并获取回复
bool send_at_cmd(char* cmd, char* response) {
    char buffer[64] = {0};
    bool result = false;
    USART_SendString(USART1, cmd);
    HAL_Delay(500);
    USART_ReceiveString(USART1, buffer);
    if (strstr(buffer, response)) {
        result = true;
    }
    return result;
}

// 初始化 ESP8266 模块
bool esp8266_init(void) {
    if (send_at_cmd(AT_CMD, "OK")) {
        if (send_at_cmd(AT_RST, "ready")) {
            if (send_at_cmd(AT_CWMODE, "OK")) {
                if (send_at_cmd(AT_CWJAP, "OK")) {
                    if (send_at_cmd(AT_CIFSR, "OK")) {
                        if (send_at_cmd(AT_CIPMUX, "OK")) {
                            if (send_at_cmd(AT_CIPSERVER, "OK")) {
                                return true;
                            }
                        }
                    }
                }
            }
        }
    }
    return false;
}

int main(void) {
    // 初始化 TFT 屏幕
    TFTLCD_Init();

    // 初始化 ESP8266 模块
    if (esp8266_init()) {
        esp8266_state = ESP_CONNECTED;
    }

    while (1) {
        // 检测 ESP8266 是否连接上 WiFi 网络
        if (esp8266_state == ESP_CONNECTED) {
            // TODO: 此处可进行其他操作
        }
    }
}
