基于STM32F103RCT6开发HAL库CubeIDE简单任务调度作为刚入门的小白检测调试是否有问题有需要的朋友可以作为参考。实现模拟任务调度OLEDADCRTC时钟ds18b20光敏传感器BEEP按键CAN通信UART通信ws2812B灯TTL转USB串口大概就这些外设。芯片配置图ws2812b是通过最简单的NOP延时进行即通过IO口操作。OLED初始播放公司logo按下按键后显示RTC时钟和温度传感器数据按键也控制蜂鸣器按下后响再次按下后反转电平然后通过光敏电阻进行ADC转换控制其中一个灯的亮度。uart在电脑上的串口调试助手进行输入输出can通信通过zprocan软件致电原子usbcanfd设备进行通信。其中还有ook无线通信但是还没有实现。下面提供主函数代码块/* USER CODE BEGIN Header */ /** ****************************************************************************** * file : main.c * brief : Main program body ****************************************************************************** * attention * * Copyright (c) 2026 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************** */ /* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include main.h #include adc.h #include can.h #include rtc.h #include usart.h #include gpio.h /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ #include stdio.h #include string.h #include ds18b20.h #include oled.h #include bmp.h #include ws2812b.h /* USER CODE END Includes */ /* Private typedef -----------------------------------------------------------*/ /* USER CODE BEGIN PTD */ typedef struct{ uint8_t run;//调度标志 uint16_t timCount;//时间片计数值 uint16_t timRload;//时间片重载值 void (*pTaskFuncCb)(void);//函数指针变量 } TaskComps_t;
