problem in the interrupt routine

Hi,

I always get stuck with the problem that when I use more than 5 inputs, the mbed gets stuck in the routine I wrote for the Interrupt pin. If I put // for 1 of the pin declarations, it goes through the Interrupt routine without any problem.

I use a mbed nxp lpc11u24 and an LCD that I control with the KS0108 library.

Working:

DigitalIn DOWN_BUTTON_PIN(p19);
//DigitalIn UP_BUTTON_PIN(p23);
DigitalIn LEFT_BUTTON_PIN(p7);
DigitalIn RIGHT_BUTTON_PIN(p30);
DigitalIn COUNT_CONTACT_PIN(p20);
InterruptIn TurnContact(p18);

Not working:

DigitalIn DOWN_BUTTON_PIN(p19);
DigitalIn UP_BUTTON_PIN(p23);
DigitalIn LEFT_BUTTON_PIN(p7);
DigitalIn RIGHT_BUTTON_PIN(p30);
DigitalIn COUNT_CONTACT_PIN(p20);
InterruptIn TurnContact(p18);

The code for the interrupt routine would probably help.

Jonas, without more details, there is not much we can help with. Try to provide as much details as possible
