SIGINT(Signal Interrupt)是一个POSIX信号,通常用于中断前台进程。当用户按下Ctrl+C组合键时,操作系统会向当前的前台进程发送SIGINT信号。这个信号的主要作用是提供一种用户友好的方式来中断正在运行的程序,允许用户终止不再需要或行为异常的进程。 2. 列举可能导致程序接收到SIGINT信号的常见情况 用户操作:用户在终端中...
Hi, hard to say, it could be wrong init of peripheral, interrupt and/or rtos if used. Try to step the code to see where it goes away. Or share
