用移植到stm32的ucos写串口中断为什么一直死机啊，研究快两天了，请大侠指点一二。谢谢


中断处理函数

应该是向量表不对
个人感觉

ucos的cortexm3移植模板均没有设置NVIC的优先级分组，使用的是默认级别，
当用户添加自己中断服务时应该将Tmr_TickISR_Handler调为最高，OSPendSV调为最低，自己的中断服务处于中间即可！

                                 你这个中断处理程序只是接收中断处理，不是写中断。如果是写中断的话，只要你设置写中断允许，因为此时串口发送寄存器这时候本身就是空的，所以系统就会马上进到你现在的中断处理函数中，而你又没有对写中断做处理，系统就会死机。

是不是答非所问了？别人没见开了写中断，哪有你说的情况？！

楼上各位能给我发一份stm32+ucosii上串口中断的完整代码吗？最近我也在学习ucosii，但是没有什么资料，在学串口中断的时候不知道他和没有系统的有什么区别，求救！

不知大侠的问题是如何解决的，我现在也遇到了相似的问题，希望共同讨论一下。

shahexu

是你中断向量表的问题，换个最新的stm32f10x_vector.c然后在调试下
