前面我们已经实现点灯下面就做一些数据交互的内容先搞一下串口让数据可以用串口打印以及通过虚拟终端显示出来就相当于有个显示屏可以显示数据了。

三、STM32CubeMX配置串口
1、配置开启USART1
开启USART1配置为异步模式并设置全局中断就可以看到右侧的引脚PA9、PA10为TX和RX设置底板的时候也可以通过这里来确认引脚位置避免搞反了 设置属性为9600比特率、8个数据位、一个停止位无奇偶校验
2、设置usart中断优先级
设置优先级 3、配置外设独立生成.c和.h
配置外设生成独立的.c和.h否则我们后面就找不到usart.c和usart.h了都在main.c中了这种结构太差了所以建议这里都勾选一下 参数设置我们使用默认的即可所以这里最简单的串口配置就完成了时钟我们这里也暂时不配置使用HSE。 可以直接右上角 GENERATE CODE生成代码然后打开MDK工程了。
四、MDK串口收发代码中断回调接收后发送接收到的内容
MDK中主要改三个地方usart.c、usart.h、stm32f1xx_it.c
1、usart.h
usart.h我们在用户可添加的位置增加相关宏和全局变量这里设置了接收中断的缓存大小为1一个字节一个字节接收处理

}
#endif#endif /* __USART_H__ */
2、usart.c
usart.c增加中断处理以及中断回调在回调中处理接收内容HAL_UART_RxCpltCallback回调中我这里是根据报文头和报尾确定一包数据后进行业务处理调用这里暂时收到什么就发送什么
/* USER CODE BEGIN Header */

}/* USER CODE BEGIN 1 */
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{if(huart-Instance USART1){//printf(uart recv now:%02x , aRxBuffer[0]);//printf(\r\n);HAL_UART_Transmit(huart1, aRxBuffer, 1, 1000);while(__HAL_UART_GET_FLAG(huart1, UART_FLAG_TC) ! SET);}
}
/* USER CODE END 1 */
3、stm32f1xx_it.c
stm32f1xx_it.c中根据全局中断的回调判断串口状态并调用接收中断

}/* USER CODE BEGIN 1 *//* USER CODE END 1 */
之后mdk进行编译生成hex即可这个之前已经章节已经说过了不再赘述。
五、创建虚拟串口并通过Proteus配置及仿真串口通信
1、创建虚拟串口
参考我这里推荐的串口工具创建一组虚拟串口https://blog.csdn.net/weixin_39510813/article/details/135069554?spm1001.2014.3001.5502 或者使用其它虚拟串口工具也可以只要保证后续有串口可用即可。
2、添加串口元器件及虚拟终端
P后搜索COMPIM后添加 添加虚拟终端在仪器栏选择VIRTUAL TERMINAL即虚拟终端后添加
3、接线配置元器件并烧入hex
上节的LED灯我们先可以不动然后P9、P10对应的口接TXD、RXD相当于将STM32的TX和RX映射到电脑的虚拟串口上然后虚拟终端的RX链接串口的RX即可这样我们通过虚拟串口工具虚拟两个串口一个串口分配给STM32来映射一个用来通过串口工具在电脑上进行收发模拟和STM32的串口进行收发。 对于串口原件还需要选择一下串口设置一下波特率、停止位这些 虚拟终端也需要配置一下 之后在STM32元器件上配置一下hex和时钟频率
4、进行仿真测试
开始仿真并运行然后通过串口工具定时发送即可
5、可能的问题
1、虚拟终端的串口有时候无法弹出根据这里顺利解决了调试-》恢复弹出窗口
https://blog.csdn.net/qq_36047832/article/details/90609487
2、此外似乎STM32回显返回给串口的内容总是和发送给STM32的内容不一致发送的时候是对的但是返回的时候是乱码最后发现接收中断的地方没有对接收空间进行memset导致了乱码此外还可能和时钟频率有关系适当调高时钟频率 六、最后
这样子基于串口通信的STM32应用开发基本就入门了串口通信由于比较常见所以这里先简要总结了一下后续的内容就可以通过串口来打印日志了STM32F103有两组串口一组我们可以用来打印日志一组用来和外部通信做交互。接下来我们接着去总结一下按键、蜂鸣器、定时器、看门狗等内容再考虑继续往下总结I2C、ADC、SPI等接口来读取一些传感器信息以及读写flash等。
