#define NVIC_PriorityGroup_2 ((uint32_t)0x500) /*!< 2 bits for pre-emption priority
ebox_init()中使用了中断分组。
取值范围是0-3.最大值应该是3.所以不知道你这个5是怎么设置过去的。
代码原来的是4也是不对的。
做如下修改
if(preemption_priority > 3)preemption_priority = 3;
if(sub_priority > 3)sub_priority = 3;
系统默认优先级0,0
void interrupt(IrqType type, FunctionalState enable, uint8_t preemption_priority = 0, uint8_t sub_priority = 0);
如果你想修改默认的优先级设置
uart3.interrupt(RxIrq, ENABLE, 0-3,0-3);
