.Rtthread3.0.3includerthw.h(10): error:  #147: declaration is incompatible with "extern void rt_hw_interrupt_disable(void)"  (declared at line 95 of ".Rtthread3.0.3includertthread.h") extern rt_base_t rt_hw_interrupt_disable(void);

声明冲突，禁用中断函数的返回值类型需要一直，在单片机系统中，它们指的是一个东西。只是“称呼”不一样。

• 把extern void rt_hw_interrupt_disable(void) 改为
•  extern rt_base_t rt_hw_interrupt_disable(void)
