if(timerCounter>=1){ Serial.println("Timerinterruptevent!");timerCounter=0;} delay(100);} 代码解释 定时器中断：配置定时器1工作在CTC（ClearTimeronCompareMatch）模式，设置比较匹配值为15624，预分频为1024，大约每隔1秒触发一次定时器中断。在定时器中断服务
我们将为定时器中断向量定义一个中断处理程序,称为“TIMER0_COMPA_vect”。在这个中断处理程序中,我们将执行循环中使用的所有操作。 // Interrupt is called once a millisecond, SIGNAL(TIMER0_COMPA_vect) { unsigned long currentMillis = millis(); sweeper1.Update(currentMillis); //if(digitalRead(2) ==...
timer1.attach_ms(interrupt_time, timerIsr); // 打开定时器中断 interrupts(); //打开外部中断 } void loop() { if(timer_flag==1) { //判断是否发生定时器中断,这里是 interrupt_time ms发生一次 timer_flag=0; //清除标记 }} //定时器中断处理函数,其功能主要为了输出编码器得到的数据 void timerI...

2) 接下来就是中断程序,网上很多写中断的例子,我都试过但失败了,最后去查看interrupt.h才找到中断程序的定义使用(仅限Arduino IDE),格式:ISR(中断向量){中断程序;}代码如下:ISR(TIMER1_OVF_vect){ // TIMER1_OVF_vect是中断溢出向量,不同芯片具体定义还是要去头文件定义和技术文档查看,执行溢出中断程序后,...

This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important fe
