how wiringOp interrupt works??

isan · Published in 2016-9-20 18:07:29

I install Jessie server / armbian on orange pi one and install wiring op on it from this link https://github.com/zhaolei/WiringOP

and for test interrupt I use this example form https://github.com/n.../examples/isr.c

as he said in comment for test write

gpio mode 0 up
gpio mode 0 down

Copy code

in other terminal , I did this and it just print waiting...

my question is , Is wiringPiISR working on orange pi one?

If the answer is yes, what should happen in this example?

Is it need any thing to connect to the pin Externally?

or can give me an other example for interrupt?

wiringPiISR isn't working on orange pi.

There are no functions of the interrupt in GPIO of OPI.

So, what should I do?

waitForInterrupt doesn't also work in OPI.
Please use RPI

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

I tried this 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;
}

Copy code

But An error occurred.

sudo ./test1
[wiringPiISR

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

Please show me your sample source code

I sent Pull Request.

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.

#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;
}

Copy code

This is test result.
