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...

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 1 const byte ledPin = 13; //LED的引脚 2 const byte interruptPin = 2; //中断源引脚,根据所用板子查表得到中断编号interrupt 3 volatile byte state = LOW; 4 5 vo...

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}
{ // allow I2C requests that don't require a register read // for example, some devices using an interrupt pin to signify new data available // do not always require the register read so upon interrupt you call Wire.requestFrom() if (theRegister != I2C_REGISTER_NOT_SPECIFIED) { Wire....
Below is code putting all of these together. You’ll notice I’m using cli() before enabling the interrupts and sei() afterward. cli() turns interrupts off while we’re messing with them and then sei() turns them back on. Also, you should include avr/interrupt.h at the top of the ...
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, ...
