单片机型号：STM32F070RBT6

使用MDK移植，或者使用RT—Thread-studio创建工程，同样跑的timeslice_sample的示例程序，运行结果都不一样，并且与文档中心或者内核实验手册描述的结果都不一样。

代码如下

```c
#include <rtthread.h>

#define THREAD_STACK_SIZE	1024
#define THREAD_PRIORITY	    20
#define THREAD_TIMESLICE    10

/* 线程入口 */
static void thread_entry(void* parameter)
{
    rt_uint32_t value;
    rt_uint32_t count = 0;

value = (rt_uint32_t)parameter;
    while (1)
    {
        if(0 == (count % 5))
        {           
            rt_kprintf("thread %d is running ,thread %d count = %d\n", value , value , count);

if(count > 200)
                return;            
        }
         count++;
     }  
}

int timeslice_sample(void)
{
    rt_thread_t tid;
    /* 创建线程1 */
    tid = rt_thread_create("thread1", 
                            thread_entry, (void*)1, 
                            THREAD_STACK_SIZE, 
                            THREAD_PRIORITY, THREAD_TIMESLICE); 
    if (tid != RT_NULL) 
        rt_thread_startup(tid);

/* 创建线程2 */
    tid = rt_thread_create("thread2", 
                            thread_entry, (void*)2,
                            THREAD_STACK_SIZE, 
                            THREAD_PRIORITY, THREAD_TIMESLICE-5);
    if (tid != RT_NULL) 
        rt_thread_startup(tid);
    return 0;
}

/* 导出到 msh 命令列表中 */
MSH_CMD_EXPORT(timeslice_sample, timeslice sample);
```

MDK移植运行结果如下：
```
msh >timeslice_sample

使用RT—Thread-studio创建工程，跑timeslice_sample的示例程序运行结果如下：
```
msh >timeslice_sample
msh >thread 1 is running ,thread 1 count = 0
thread 1 is running ,thread 1 count = 5
thread 1 is running ,thread 2 count = 135thread 1 is running ,thread 1 count = 15
thread 1 is running ,thread 2 count = 205thread 1 is running ,thread 1 count = 25
thread 1 is running ,thread 1 count = 30
thread 1 is running ,thread 1 count = 35
thread 1 is running ,thread 1 count = 40
thread 1 is running ,thread 1 count = 45
thread 1 is running ,thread 1 count = 50
thread 1 is running ,thread 1 count = 55
thread 1 is running ,thread 1 count = 60
thread 1 is running ,thread 1 count = 65
thread 1 is running ,thread 1 count = 70
thread 1 is running ,thread 1 count = 75
thread 1 is running ,thread 1 count = 80
thread 1 is running ,thread 1 count = 85
thread 1 is running ,thread 1 count = 90
thread 1 is running ,thread 1 count = 95
thread 1 is running ,thread 1 count = 100
thread 1 is running ,thread 1 count = 105

thread 1 is running ,thread 1 count = 120
thread 1 is running ,thread 1 count = 125
thread 1 is running ,thread 1 count = 130
thread 1 is running ,thread 1 count = 135
thread 1 is running ,thread 1 count = 140
thread 1 is running ,thread 1 count = 145

thread 1 is running ,thread 1 count = 175
thread 1 is running ,thread 1 count = 180

如上所示，结果不一样
