I get wiring op from this link
https://github.com/WereCatf/WiringOP
and install it and interrupt w ...

I tried this code.

code:

#include <wiringPi.h>
#include <stdlib.h>
#include <stdio.h>
#define pin 0
void signal(void){
printf("Signal\n");
}
int main(void){
if(wiringPiSetup() == -1) {
printf("wiringPiSetup Error\n");
}
pinMode(pin,INPUT);
wiringPiISR(pin, INT_EDGE_FALLING, signal );
// wiringPiISR(pin, INT_EDGE_RISING, signal );
while(1) {
sleep(10000);
}
return 0;
}

But An error occurred.

sudo ./test1
[wiringPiISR

2677] the pin:0 is invalid, please check it over!

Please show me your sample source code

You can copy modified source from here.
You can use wiringPiISR with all GPIO(GPIO0-GPIO26).
You need to load gpio_sunxi.
waitForInterrupt function don't work.

Because a device file is being read periodically.

I tested armbian.
This is test code.

code:

#include <wiringPi.h>
#include <stdlib.h>
#include <stdio.h>
void signal_both(void){
printf("Signal Both\n");
}
void signal_falling(void){
printf("Signal Falling\n");
}
void signal_rising(void){
printf("Signal Rising\n");
}
int main(int argc, char **argv){
int mode=INT_EDGE_BOTH;
int pin = 0;
if(wiringPiSetup() == -1) {
printf("wiringPiSetup Error\n");
}
if (argc == 2) {
mode = atoi(argv[1]);
}
if (argc == 3) {
mode = atoi(argv[1]);
pin = atoi(argv[2]);
}
pinMode(pin,INPUT);
printf("pin=%d\n",pin);
if ( mode == INT_EDGE_BOTH) {
printf("INT_EDGE_BOTH\n");
wiringPiISR(pin, INT_EDGE_BOTH, signal_both );
} else if ( mode == INT_EDGE_FALLING) {
printf("INT_EDGE_FALLING\n");
wiringPiISR(pin, INT_EDGE_FALLING, signal_falling );
} else if ( mode == INT_EDGE_RISING) {
printf("INT_EDGE_RISING\n");
wiringPiISR(pin, INT_EDGE_RISING, signal_rising );
}
while(1) {
sleep(10000);
}
return 0;
}

This is test result.

code:

orangepi@orangepipc:~/test$ sudo ./test2 1 15
pin=15
INT_EDGE_FALLING
Signal Falling

^Corangepi@orangepipc:~/test$ sudo ./test2 2 15
