attachInterrupt problem on RPi

The Archive Raspberry Pi
1

Hi

I’m unable to get the attachInterrupt function to call the interrupt function

Using 0.5.1-pi.14

I’ve tried GPIO4/GPIO17 with FALLING/RISING/CHANGE - no activity seen

Are there some pins that do work?

Thanks

Regards

Julian

Hi there. Currently interrupts are not supported for the RPi on our platform. It may be something we work in in a future update but I can’t confirm that this would take place any time soon. I apologize for any inconvenience.

Hi

I’ve worked around this problem by calling the WiringPi functions directly as follows

extern "C" int wiringPiISR (int pin, int edgeType, void (* function) (void));
#define INT_EDGE_FALLING 1
#define INT_EDGE_RISING 2
#define INT_EDGE_BOTH 3
wiringPiISR (GPIO4, INT_EDGE_FALLING, isrFunction);

Hi

It turns out that the wiringPi package must be installed for this to work

sudo apt-get install wiringpi
