Oragnepi zero Plus H5 ISR Problem

moonki123 · June 1, 2017

Hi i wonder why ISR result is strange

first i test in orangepi zero Plus H5

that result is repeated infinite recall function

summary - recall infinite function if i input interrupt pin(button)

i test

result repeat

second i test in orangepi zero(H2)

that result is only called function once

#include <wiringPi.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.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;
}
