STM32fo51k8驱动ESP8266联网获取时间并在1.44lcd屏幕上面显示实时时间，用STM32CubeMX生成详细代码，写出所以代码

好的，我会为你提供一个基于STM32F051K8的ESP8266联网获取时间并在1.44寸LCD屏幕上显示实时时间的详细代码。以下是实现该功能的步骤和代码：

1. 配置STM32F051K8的时钟和GPIO引脚，使其可以与ESP8266和LCD屏幕通信。

/* Configure USART1 clock and GPIO */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE);

/* Configure LCD GPIO */
GPIO_InitTypeDef GPIO_InitStruct;
GPIO_InitStruct.GPIO_Pin = GPIO_Pin_6 | GPIO_Pin_7 | GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10;
GPIO_InitStruct.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitStruct.GPIO_Speed = GPIO_Speed_2MHz;
GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;
GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;
GPIO_Init(GPIOB, &GPIO_InitStruct);

/* Configure ESP8266 GPIO */
GPIO_InitStruct.GPIO_Pin = GPIO_Pin_2 | GPIO_Pin_3;
GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AF;
GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;
GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_UP;
GPIO_Init(GPIOA, &GPIO_InitStruct);

GPIO_PinAFConfig(GPIOA, GPIO_PinSource2, GPIO_AF_1);
GPIO_PinAFConfig(GPIOA, GPIO_PinSource3, GPIO_AF_1);

2. 配置USART1串口，用于与ESP8266通信。

USART_InitTypeDef USART_InitStruct;
USART_InitStruct.USART_BaudRate = 115200;
USART_InitStruct.USART_WordLength = USART_WordLength_8b;
USART_InitStruct.USART_StopBits = USART_StopBits_1;
USART_InitStruct.USART_Parity = USART_Parity_No;
USART_InitStruct.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStruct.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
USART_Init(USART1, &USART_InitStruct);

USART_Cmd(USART1, ENABLE);

3. 配置ESP8266网络连接并获取时间。在这个例子中，我们使用ESP8266模块连接到NTP服务器获取时间。这里我们使用AT指令来控制ESP8266模块。

/* Configure ESP8266 */
usart_send_str("AT\r\n");
usart_wait_for_response("OK\r\n", 1000);

usart_send_str("AT+CWMODE=1\r\n");
usart_wait_for_response("OK\r\n", 1000);

usart_send_str("AT+CWJAP=\"SSID\",\"PASSWORD\"\r\n");
usart_wait_for_response("OK\r\n", 10000);

usart_send_str("AT+CIPSNTPCFG=1,1,\"pool.ntp.org\"\r\n");
usart_wait_for_response("OK\r\n", 1000);

usart_send_str("AT+CIPSNTPTIME?\r\n");
char* response = usart_wait_for_response("+CIPSNTPTIME:", 10000);

char* p = strstr(response, "+CIPSNTPTIME:");
if (p != NULL) {
  p += strlen("+CIPSNTPTIME:");
  time_t timestamp = atol(p);
  struct tm timeinfo;
  gmtime_r(&timestamp, &timeinfo);
}

4. 配置LCD屏幕并显示实时时间。

/* Configure LCD screen */
lcd_init();

/* Display time */
while (1) {
  char buffer[32];
  strftime(buffer, sizeof(buffer), "%Y-%m-%d %H:%M:%S", &timeinfo);
  lcd_clear();
  lcd_write_string(buffer);
  delay(1000);
}

完整代码如下：

#include "stm32f0xx.h"
#include "lcd.h"
#include <time.h>
#include <stdlib.h>
#include <string.h>

void usart_send_char(char c) {
  while (!(USART1->ISR & USART_ISR_TXE));
  USART1->TDR = c;
}

void usart_send_str(const char* str) {
  while (*str) {
    usart_send_char(*str++);
  }
}

char usart_receive_char(void) {
  while (!(USART1->ISR & USART_ISR_RXNE));
  return USART1->RDR;
}

int usart_receive_str(char* buffer, int bufsize, int timeout) {
  int received = 0;
  int start = HAL_GetTick();
  while (received < bufsize - 1) {
    if (HAL_GetTick() - start > timeout) {
      break;
    }
    char c = usart_receive_char();
    if (c == '\r' || c == '\n') {
      if (received == 0) {
        continue;
      } else {
        break;
      }
    }
    buffer[received++] = c;
  }
  buffer[received] = '\0';
  return received;
}

char* usart_wait_for_response(const char* expected, int timeout) {
  static char buffer[256];
  int start = HAL_GetTick();
  while (1) {
    if (HAL_GetTick() - start > timeout) {
      return NULL;
    }
    int received = usart_receive_str(buffer, sizeof(buffer), timeout);
    if (received > 0) {
      if (strstr(buffer, expected) != NULL) {
        return buffer;
      }
    }
  }
}

int main(void) {
  RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOB, ENABLE);
  GPIO_InitTypeDef GPIO_InitStruct;
  GPIO_InitStruct.GPIO_Pin = GPIO_Pin_6 | GPIO_Pin_7 | GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10;
  GPIO_InitStruct.GPIO_Mode = GPIO_Mode_OUT;
  GPIO_InitStruct.GPIO_Speed = GPIO_Speed_2MHz;
  GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;
  GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;
  GPIO_Init(GPIOB, &GPIO_InitStruct);

  RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);
  RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE);

  GPIO_InitStruct.GPIO_Pin = GPIO_Pin_2 | GPIO_Pin_3;
  GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AF;
  GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;
  GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_UP;
  GPIO_Init(GPIOA, &GPIO_InitStruct);

  GPIO_PinAFConfig(GPIOA, GPIO_PinSource2, GPIO_AF_1);
  GPIO_PinAFConfig(GPIOA, GPIO_PinSource3, GPIO_AF_1);

  USART_InitTypeDef USART_InitStruct;
  USART_InitStruct.USART_BaudRate = 115200;
  USART_InitStruct.USART_WordLength = USART_WordLength_8b;
  USART_InitStruct.USART_StopBits = USART_StopBits_1;
  USART_InitStruct.USART_Parity = USART_Parity_No;
  USART_InitStruct.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
  USART_InitStruct.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
  USART_Init(USART1, &USART_InitStruct);

  USART_Cmd(USART1, ENABLE);

  usart_send_str("AT\r\n");
  usart_wait_for_response("OK\r\n", 1000);

  usart_send_str("AT+CWMODE=1\r\n");
  usart_wait_for_response("OK\r\n", 1000);

  usart_send_str("AT+CWJAP=\"SSID\",\"PASSWORD\"\r\n");
  usart_wait_for_response("OK\r\n", 10000);

  usart_send_str("AT+CIPSNTPCFG=1,1,\"pool.ntp.org\"\r\n");
  usart_wait_for_response("OK\r\n", 1000);

  usart_send_str("AT+CIPSNTPTIME?\r\n");
  char* response = usart_wait_for_response("+CIPSNTPTIME:", 10000);

  struct tm timeinfo;
  char* p = strstr(response, "+CIPSNTPTIME:");
  if (p != NULL) {
    p += strlen("+CIPSNTPTIME:");
    time_t timestamp = atol(p);
    gmtime_r(&timestamp, &timeinfo);
  }

  lcd_init();

  while (1) {
    char buffer[32];
    strftime(buffer, sizeof(buffer), "%Y-%m-%d %H:%M:%S", &timeinfo);
    lcd_clear();
    lcd_write_string(buffer);
    delay(1000);
  }
}

这是一个简单的示例，可以帮助你了解如何使用STM32F051K8、ESP8266和LCD屏幕实现从NTP服务器获取时间并显示实时时间。当然，在实际项目中，你需要考虑更多的细节和错误处理。
