The next way to use Arduino timer interrupt is by comparing the timer count to a specific value. Every time the timer’s count is equal to that value, the interrupt occurs. This is calledTimer Compare Interrupt. When using timer overflow interrupt, the interrupt triggers after 255 counts. I...
在我们的情况下,我们不会检测到信号的下降沿,所以我们通过下降。 constbyte interruptPin=13;// 13 对应板载LED 2 对应433中断0volatilebyte interruptCounter=0;intnumberOfInterrupts=0;voidsetup(){Serial.begin(115200);pinMode(interruptPin,INPUT_PULLUP);attachInterrupt(digitalPinToInterrupt(interruptPin),handle...

Arduino Interrupt Call Stack For normal function calls, a stack is used to save and restore the Program Counter (PC). The PC contains the address of the current instruction. When a subroutine is called, the value of the PC is pushed onto the stack, and when the subroutine is finished, ...
