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

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,和芯片相连的话看芯片有没有虚焊,好多我们搞硬件的都拌.

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。...
