中断方式的任务恢复，会卡死在xTaskResumeFromISR（）函数

Howareyou

为什么会这样，小弟上传源码，求大神解解疑惑

出现这个问题是因为你在不受FreeRTOS管理的中断里面调用了FreeRTOS的API。

修改下你FreeRTOSConfig.h文件里面的，如下四个参数改成我的这样，然后试试看

1. /* The lowest interrupt priority that can be used in a call to a "set priority"
   
2. function. */
   
3. #define configLIBRARY_LOWEST_INTERRUPT_PRIORITY                        0x0f
   
4. 
   
5. /* The highest interrupt priority that can be used by any interrupt service
   
6. routine that makes calls to interrupt safe FreeRTOS API functions.  DO NOT CALL
   
7. INTERRUPT SAFE FREERTOS API FUNCTIONS FROM ANY INTERRUPT THAT HAS A HIGHER
   
8. PRIORITY THAN THIS! (higher priorities are lower numeric values. */
   
9. #define configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY        0x01
   
10. 
    
11. /* Interrupt priorities used by the kernel port layer itself.  These are generic
    
12. to all Cortex-M ports, and do not rely on any particular library functions. */
    
13. #define configKERNEL_INTERRUPT_PRIORITY                 ( configLIBRARY_LOWEST_INTERRUPT_PRIORITY << (8 - configPRIO_BITS) )
    
14. /* !!!! configMAX_SYSCALL_INTERRUPT_PRIORITY must not be set to zero !!!!
    
15. See http://www.FreeRTOS.org/RTOS-Cortex-M3-M4.html. */
    
16. #define configMAX_SYSCALL_INTERRUPT_PRIORITY         ( configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY << (8 - configPRIO_BITS) )
    
17.

FreeRTOS管理的中断？我直接配置的TIM2的中断，能进入中断，可是会卡在那！我要怎么配置中断才算是RTOS管理的中断
