In system programming, an interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. An interrupt alerts the processor to a high-priority condition requiring the interruption of the current code the processor is executing. The processor ...

首先使用vs code打开AliOS-Things文件夹,然后在examples下新建一个文件夹AliOSLearning。 为了git管理版本方便,我们需要把app/example/AliOSLearning/这个文件夹添加到git的忽略文件夹。在vs code中打开AliOS-Things文件夹的.gitignore文件,添加一行app/example/AliOSLearning/,这样就把文件夹AliOSLearning列为忽略文件夹...
// Disable CPU interrupts and clear all CPU interrupt flags: IER = 0x0000; IFR = 0x0000; // Initialize the PIE vector table with pointers to the shell Interrupt // Service Routines (ISR). // This will populate the entire table, even if the interrupt is not used in this example. This...

1 pinMode(interruptPin, INPUT_PULLUP); 最后,我们使用attachInterrupt函数将中断附加到引脚。它接收中断号码作为第一个参数,作为第二个参数的中断服务程序,以及第三个中断模式。 在第一个参数中,我们将使用 digitalPinToInterrupt函数,该函数接收中断引脚作为输入,将实际的数字引脚转换为特定的中断号[6]。 作为第二...
