这家伙很懒，什么也没写！

图片发不出来，补上代码
```c
void fun_test(void)
{
    uint16_t delay_temp = 1000;
    rt_timer_control(&display_symble_blink_timer2_tcb, RT_TIMER_CTRL_SET_TIME, &delay_temp);
    rt_timer_start(&display_symble_blink_timer2_tcb);
}
void display_init(void)
{
    display_symble_blink_mode = Blink_Mode_NONE;
    display_symble_blink_state = 1;
    
    rt_timer_init(&display_symble_blink_timer_tcb,          // 显示符号闪烁定时器
                  "display_symble_blink_timer",
                  display_symble_blink_timer,
                  RT_NULL, 1000,
                  RT_TIMER_FLAG_PERIODIC | RT_TIMER_FLAG_SOFT_TIMER);
    
    rt_timer_init(&display_symble_blink_timer2_tcb,          // 显示符号闪烁定时器
                  "display_symble_blink_timer2",
                  display_symble_blink_timer2,
                  RT_NULL, 1000,
                  RT_TIMER_FLAG_PERIODIC | RT_TIMER_FLAG_SOFT_TIMER);
                  
    rt_timer_start(&display_symble_blink_timer_tcb);
    fun_test();
//    uint16_t delay_temp = 1000;
//    rt_timer_control(&display_symble_blink_timer2_tcb, RT_TIMER_CTRL_SET_TIME, &delay_temp);
//    rt_timer_start(&display_symble_blink_timer2_tcb);
}
```
