的方法解决一下，现在和大家分享一下我自己的经验。一、串口在串口中断进不去的情况下，这是我所经历的最普遍的一个问题，身边的朋友也有好多对这个问题有困惑。有几种解决方法，其一，检查硬件，也就是从PCB上面看和我们的串口相连的走线，电阻检查有没有焊错型号，和芯片相连的话

STM32F4定时器5 中断异常进不去问题出现问题现象：用定时器5来发脉冲，有时候当指令发送后，定时器不发脉冲，debug时发现程序执行到打开定时器5后，进不去中断，之后就一直进不去中断，才导致发不

今天发现定时器中断总是进不去.发现了2个问题一.生成的配置文件有问题需要点好几次NVIC中断,才能生成合格的代码. 生成的tim.c文件中应该有HAL_NVIC_EnableIRQ

中断接收问题描述：在while（1）里面进行串口的发送，在中断进行串口的接收，但是接收一会后就再也进不去中断了。有可能串口发送的过程中停止了串口接收中断。...

以前我记得有个设置.可以像 PADS一样.拖动元件,与元件相连接的布线会自动更改位置.这在布局中比较方便.但是很长时间没用到这个功能忘了如何设置了.
