HIGH 高电平触发(该中断模式仅适用于Arduino due) 如果不需要使用外部中断了,可以用中断分离函数detachInterrupt(interrupt )来取消这一中断设置。 Example Code用外部中断实现LED的亮灭切换 1constbyteledPin =13;//LED的引脚2constbyteinterruptPin =2;//中断源引脚,根据所
With the help of this function the interrupt is attached in the code. Three parameters are presents in attachInterrupt function the 1stis interrupt pin in the care of this example the interrupt pin is 2, and the 2ndis ISR function which is named as Glow, and the 3rdis mode in this examp...

Simple example for receiving https://github.com/sui77/rc-switch/ */#include<RCSwitch.h> RCSwitch mySwitch =RCSwitch(); void setup(){Serial.begin(9600); mySwitch.enableReceive(0);// Receiver on interrupt 0 => that is pin #2}
If code size or timer usage matters, look at these examples. The TinyReceiver example uses the TinyIRReceiver library which can only receive NEC, Extended NEC, ONKYO and FAST protocols, but does not require any timer. They use pin change interrupt for on the fly decoding, which is the ...
One of the pins with external interrupt function (INT0, INT1,…) must be reserved for the debugger. With Arduino Uno this can be either digital pin 2 or 3 (PD2 or PD3 pin of the MCU). For Arduino Mega there are more options. By default, INT0 pin (Uno pin 2, Mega pin 21) ...
pinMode(interruptPin,INPUT_PULLUP); 1. 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]。
打开file-example-mpu6050-mpu6050_DMP6,有现成的实例代码。由于我的esp32的板载LED灯的pin number是2,修改#define LED_PIN 13为2。中断pin 2修改为#define INTERRUPT_PIN 13 //修改后 #define INTERRUPT_PIN 13 // use pin 2 on Arduino Uno & most boards #define LED_PIN 2 // (Arduino is 13, ...
