STM32fo51k8驱动1.44,lcd 屏和ESP8266在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，以下是基于STM32CubeMX生成的详细代码，实现将ESP8266和1.44寸LCD屏幕连接到STM32F051K8上，同时显示实时时间的功能： 首先，需要配置STM32F051K8的GPIO口和时钟： ```c // 定义引脚号 #define LCD_CE_Pin GPIO_PIN_4 #define LCD_CE_GPIO_Port GPIOA #define LCD_RST_Pin GPIO_PIN_5 #define LCD_RST_GPIO_Port GPIOA #define LCD_DC_Pin GPIO_PIN_6 #define LCD_DC_GPIO_Port GPIOA #define LCD_DIN_Pin GPIO_PIN_7 #define LCD_DIN_GPIO_Port GPIOA #define LCD_CLK_Pin GPIO_PIN_0 #define LCD_CLK_GPIO_Port GPIOB #define ESP8266_TX_Pin GPIO_PIN_6 #define ESP8266_TX_GPIO_Port GPIOB #define ESP8266_RX_Pin GPIO_PIN_7 #define ESP8266_RX_GPIO_Port GPIOB // 使能GPIO口时钟 __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_ENABLE(); // 配置LCD屏幕引脚为输出 GPIO_InitTypeDef GPIO_InitStruct = {0}; GPIO_InitStruct.Pin = LCD_CE_Pin|LCD_RST_Pin|LCD_DC_Pin|LCD_DIN_Pin; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(LCD_CE_GPIO_Port, &GPIO_InitStruct); GPIO_InitStruct.Pin = LCD_CLK_Pin; HAL_GPIO_Init(LCD_CLK_GPIO_Port, &GPIO_InitStruct); // 配置ESP8266引脚为复用推挽输出 GPIO_InitStruct.Pin = ESP8266_TX_Pin|ESP8266_RX_Pin; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Alternate = GPIO_AF0_USART1; HAL_GPIO_Init(GPIOB, &GPIO_InitStruct); // 使能USART1时钟 __HAL_RCC_USART1_CLK_ENABLE(); ``` 然后，需要配置STM32F051K8的USART1串口和时钟： ```c // 定义串口号 #define ESP8266_UART huart1 // 使能USART1时钟 __HAL_RCC_USART1_CLK_ENABLE(); // 配置USART1 ESP8266_UART.Instance = USART1; ESP8266_UART.Init.BaudRate = 115200; ESP8266_UART.Init.WordLength = UART_WORDLENGTH_8B; ESP8266_UART.Init.StopBits = UART_STOPBITS_1; ESP8266_UART.Init.Parity = UART_PARITY_NONE; ESP8266_UART.Init.Mode = UART_MODE_TX_RX; ESP8266_UART.Init.HwFlowCtl = UART_HWCONTROL_NONE; ESP8266_UART.Init.OverSampling = UART_OVERSAMPLING_16; HAL_UART_Init(&ESP8266_UART); ``` 接下来，需要编写一些控制LCD屏幕的函数： ```c void lcd_cmd(uint8_t cmd) { LCD_CE_Low(); LCD_DC_Low(); for (int i = 0; i < 8; i++) { if (cmd & 0x80) { LCD_DIN_High(); } else { LCD_DIN_Low(); } cmd <<= 1; LCD_CLK_Low(); LCD_CLK_High(); } LCD_CE_High(); } void lcd_data(uint8_t data) { LCD_CE_Low(); LCD_DC_High(); for (int i = 0; i < 8; i++) { if (data & 0x80) { LCD_DIN_High(); } else { LCD_DIN_Low(); } data <<= 1; LCD_CLK_Low(); LCD_CLK_High(); } LCD_CE_High(); } void lcd_init() { LCD_RST_High(); HAL_Delay(10); LCD_RST_Low(); HAL_Delay(10); LCD_RST_High(); HAL_Delay(10); lcd_cmd(0x21); lcd_cmd(0xB1); lcd_cmd(0x04); lcd_cmd(0x14); lcd_cmd(0x0C); lcd_cmd(0x20); lcd_cmd(0x0C); } void lcd_set_cursor(uint8_t x, uint8_t y) { lcd_cmd(0x80 | x); lcd_cmd(0x40 | y); } void lcd_clear() { for (int i = 0; i < 84; i++) { for (int j = 0; j < 6; j++) { lcd_set_cursor(i, j); lcd_data(0x00); } } } void lcd_write_char(char c) { for (int i = 0; i < 5; i++) { lcd_data(font[c - 0x20][i]); } lcd_data(0x00); } ``` 其中，`lcd_cmd`和`lcd_data`函数用于向LCD屏幕发送指令和数据，`lcd_init`函数用于初始化LCD屏幕，`lcd_set_cursor`函数用于设置光标位置，`lcd_clear`函数用于清空屏幕，`lcd_write_char`函数用于显示字符。 最后，需要编写一个函数来获取当前时间并在LCD屏幕上显示： ```c void display_time() { RTC_TimeTypeDef time; HAL_RTC_GetTime(&hrtc, &time, RTC_FORMAT_BIN); char hour[3]; char minute[3]; char second[3]; sprintf(hour, "%02d", time.Hours); sprintf(minute, "%02d", time.Minutes); sprintf(second, "%02d", time.Seconds); lcd_set_cursor(0, 0); lcd_write_char(hour[0]); lcd_write_char(hour[1]); lcd_write_char(':'); lcd_write_char(minute[0]); lcd_write_char(minute[1]); lcd_write_char(':'); lcd_write_char(second[0]); lcd_write_char(second[1]); } ``` 在这个函数中，我们使用了STM32F051K8的RTC模块来获取当前时间，并将它显示在LCD屏幕上。 完整代码如下：
