关于H7-TOOL高效检测RTOS任务栈使用率检测问题
现在部分RTOS需要使能宏定义才会检测，也有需要调用函数才可以检测，像uCOS-II这种是需要调用函数OSTaskStkChk来检测的。
如果用户开的任务比较多，任务栈也比较大，执行一轮的时间略多，C的代码如下：
/*
*********************************************************************************************************
* STACK CHECKING
*
* Description: This function is called to check the amount of free memory left on the specified task's
* stack.
*
* Arguments: prio is the task priority
*
* p_stk_data is a pointer to a data structure of type OS_STK_DATA.
*
* Returns : OS_ERR_NONE upon success
* OS_ERR_PRIO_INVALID if the priority you specify is higher that the maximum allowed
* (i.e. > OS_LOWEST_PRIO) or, you have not specified OS_PRIO_SELF.
* OS_ERR_TASK_NOT_EXISTif the desired task has not been created or is assigned to a Mutex PIP
* OS_ERR_TASK_OPT if you did NOT specified OS_TASK_OPT_STK_CHK when the task was created
* OS_ERR_PDATA_NULL if 'p_stk_data' is a NULL pointer

而H7-TOOL的RTOS Trace功能去检索的话，初步是打算采样此贴的方案，但是效率不够高，后面得找个更高效的方法
H7-TOOL检索程序系统stack和heap使用情况，方便大家使用了malloc和中断嵌套情况的监测（2023-05-03）
