..\..\Middlewares\FreeRTOS\portable\RVDS\ARM_CM3\port.c(407): error: A1586E: Bad operand types (UnDefOT, Constant) for operator (

这个错误是由于在port.c文件的第407行使用了错误的操作数类型(UnDefOT, Constant)导致的。根据引用中提到的错误信息，最后发现是main.h中的#include "stm32f1xx_hal.h"的问题。根据引用中提供的解决方法，问题可能出现在中断中使用了不正确的函数。应该将xTimerReset替换为xTimerResetFromISR。此外，引用中提到的问题可能是由于中断优先级的设置不正确导致的。需要检查FreeRTOSConfig.h文件中配置的宏configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY，确保串口中断的优先级低于该宏定义的优先级。如果不是，则需要进行修改。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
