Arduino Uno上的"pin change"中断是通过PCINT(Pin Change Interrupt)来实现的。PCINT是Arduino Uno上的一个特殊功能,它允许在特定引脚状态变化时触发中断。 在Arduino Uno上,有三个可用的PCINT引脚组,分别是PCINT0、PCINT1和PCINT2。每个组包含多个引脚,可以通过设置相应的寄存器来启用或禁用中断。 具体来...
On a standard Arduino Uno Pin 2 and 3 havePinInterrupts. Those are exclusively for a single pin and can detect RISING, FALLING and CHANGE. PinChangeInterruptsinstead are used for a whole port (they should have better named them PortChangeInterrupts) and can only detect CHANGE for a whole ...
Hardware interrupts are also easier to use in the Arduino environment. You just call the function attachInterrupt and input the interrupt number and the function to call when it triggers. But up until recently, there wasn’t a good Pin Change Interrupt library and even now it isn’t included...
a = arduino('COM4','Uno'); configurePin(a,'D3','pullup'); Display current pin mode. pinmode = configurePin(a,'D3') pinmode = 'Pullup' Clear Pin Mode This example uses: Copy CodeCopy Command Display current pin mode and reset it to 'Unset'. ...
