stm32f103zet6 ili9341(fsmc) freertos 制作数字电子时钟

配置教程请参考 STM32F103ZET6 FREERTOS 双UART 多任务多串口输出（配置教程）

主函数和配置和该教程一模一样，不需要添加什么变动

唯一需要添加的是在freertos.c 的 void StartTask02(void const * argument)中写如下代码

/* USER CODE BEGIN Header_StartTask02 */
/**
* @brief Function implementing the myTask02 thread.
* @param argument: Not used
* @retval None
*/
/* USER CODE END Header_StartTask02 */
void StartTask02(void const * argument)
{/* USER CODE BEGIN StartTask02 */char date_time[] = "2024-10-23 12:59:59";char str[30]; int year = 2024;int month = 10;int date = 23;int hour = 12;int minute = 59;int second = 59;char month_t[3];char date_t[3];char hour_t[3];char minute_t[3];char second_t[3];/* Infinite loop */for(;;){osDelay(996);second++;if(second == 60){second = 0;minute++;if(minute==60){minute = 0;hour++;if(hour==25){hour = 0;date++;if(month == 1||month == 3||month == 5||month == 7||month == 8||month == 10||month == 12){if(date == 32){date = 0;month++;if(month == 13){year++;month = 1;}}}else if(month == 2){if(date == 29){date = 0;month++;if(month == 13){year++;month = 1;}}}else{if(date == 31){date = 0;month++;if(month == 13){year++;month = 1;}}						}}}}if(date<10){sprintf(date_t,"0%d",date);}else{sprintf(date_t,"%d",date);}if(month<10){sprintf(month_t,"0%d",month);}else{sprintf(month_t,"%d",month);}if(hour<10){sprintf(hour_t,"0%d",hour);}else{sprintf(hour_t,"%d",hour);}if(minute<10){sprintf(minute_t,"0%d",minute);}else{sprintf(minute_t,"%d",minute);}if(second<10){sprintf(second_t,"0%d",second);}else{sprintf(second_t,"%d",second);}//if(month<10||date<10||hour<10||minute<10||second<10){//	sprintf(str,"%d - %d - %d %d : %d : %d",year,month,date,hour,minute,second);//}sprintf(str,"%d - %s - %s %s : %s : %s",year,month_t,date_t,hour_t,minute_t,second_t);//LCD_Clear(BLUE); 为了每次输出不会有上一次输出字符的残留,不过画面会有闪烁，看起来有些异样LCD_ShowString(40,150,360,32,16,(uint8_t*)str);}/* USER CODE END StartTask02 */
}

效果如下:
