Hi. More detail info of code:

//Sensor PIR – Security system
InterruptIn IO1(PA_0); // xDot:pin 34 – PCB: i1 Conector P1-2
InterruptIn IO2(PB_12); // xDot:pin 9 – PCB: i2 Conector P1-3
InterruptIn IO3(PB_13); // xDot:pin 10 – PCB: i3 Conector P1-4
InterruptIn IO4(PB_15); // xDot:pin 11 – PCB: i4 Conector P1-5
InterruptIn IO5(PB_14); // xDot:pin 12 – PCB: i5 Conector P1-6

void rise1() {
pc.printf(“IO1=Sensor PIR detect RISE !\r\n”); // Turn on led1 +led2
led1 = 1;
mon_cpu_pcb();
in_int=1; // Interrup arrived to PIN:P1-1
counter_1++;
wait (0.1);
led1=0;

}

void fall1() {
pc.printf(“IO1=Sensor PIR detect FALL !\r\n”); // Turn on led1 +led2
pc.printf(“IO5 -> Nr Pulse read:%d\r\n”, counter_1);

}
