I am trying to use a rising edge GPIO interrupt for KEY PAD interfacing on P2.0
to p2.5.
I setup the pin as an input
PINMODE4 = 0x00000AAA;
I also setup the IO2_INT_EN_R to enable the rising edge interrupt.
IO2_INT_CLR = 0x0000003F;
IO2_INT_EN_R = 0x0000003F;
Also then load and enable the VIC channel. I see in the docs that
EINT3 - channel 17 - is shared with GPIO interrupts.
VICVectAddr17 = (uint32)eint3_int;
VICIntEnable = (1 << 17);
When I press any key I never get any interrupt.
Can any one help????/

SCS - bit 0.
But that's not the problem, since you're using port 2. The fast GPIO bit
only pertains to port 0 and 1.
What processor are you using? LPC2.?

Ok (2368), then what I said about SCS is correct (it's slightly
different
for LPC21.. and LPC22..)
Anyway. you don't have to set any other registers for port2. These are
ALWAYS fast GPIO.
Why are you setting PINMODE4? That's not for direction, that's for
pull-up/down resistors.
You probably don't need it.
And input is the default direction.
Haven't looked at your values yet, but try removing that PINMODE4 thing.

I am trying to use a rising edge GPIO interrupt for KEY PAD interfacing on
P2.0 to p2.5.
I setup the pin as an input
PINMODE4 = 0x00000AAA;
I also setup the IO2_INT_EN_R to enable the rising edge interrupt.
IO2_INT_CLR = 0x0000003F;
IO2_INT_EN_R = 0x0000003F;
Also then load and enable the VIC channel. I see in the docs that
EINT3 - channel 17 - is shared with GPIO interrupts.
VICVectAddr17 = (uint32)eint3_int;
VICIntEnable = (1 << 17);
When I press any key I never get any interrupt.
Can any one help????/
