attachPinChangeInterrupt 是Arduino 中用于设置引脚变化中断的函数。 attachPinChangeInterrupt 函数允许你在 Arduino 板上几乎任何数字引脚上设置中断,而不仅仅是标准的外部中断引脚(如 D2 和 D3)。这对于需要监控多个引脚状态变化的项目特别有用。 函数原型 cpp attachPinChangeInterrupt(pin, ISR, mode); pin:要...
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...
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...

External Interrupts:Pins 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2)can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. ...
When you want to monitor change across any pin, you can use this pin as an interrupt instead of repeatedly monitoring the state of this pin. PWM GPIO pins All general-purpose input output pins can be used to generate PWM except digital input pins from GPIO pins 34-39. Because these pins...
=> "RC filtered" behaviour of the SPI pin on the arduino header. - Second test project : "SDK_2.6.2_EVK-MIMXRT1060\boards\evkmimxrt1060\driver_examples\lpspi\interrupt_b2b" => Same "RC filtered" behaviour of the SPI pin on the arduino header. Can you confirm which SDK you are us...
