[Problem Discussion] After the comparative test, let's talk about the problem that adding delay in the interrupt program of the stm32 microcontroller may cause the program to crash
I rarely call delay programs in interrupt functions, mainly because my predecessors taught me this when I first came into contact with microcontrollers. It is said that programs are prone to run away,...
