Good day to every one,
I do have a problem with external interrupt triggering (EINT1). Iam connecting
EINT1 as a Vectored Interrupt source to slot 0. Once executing in the test board
of LPC 2129 ARM7 controller, it is not getting triggered when EINT1 switch is
pressed.
Iam attaching the code: please help me in debugging the code:?:
******************************************************************
#include void EXTINTVectoredIRQ(void) __irq;
void main(){ IODIR1=0X00FF0000; // make port1 LED pins as o/p
PINSEL0=0X000000c0; //Change GPIO as INT1
VICIntEnable=0X00008000; // Enable INT1 VICVectCntl0=0x0000002F; //
connecting the INT1 interrupt channel to slot 0, and enabling the interrupt
VICVectAddr0=(unsigned)EXTINTVectoredIRQ; IOCLR1=0X00FF0000; // Clear
LED'swhile(1);}void EXTINTVectoredIRQ(void)
__irq{ IOSET1=0X00FF0000; // set leds EXTINT=0X00000002;
// disable EINT 1 VICVectAddr0=0x00000000; // dummy
write}*****************************************************************Many
thanks in advance !

Check the errata sheet on that processor, I recall a problem with the setting up
EINT1 of that function

Read the pin configuration register,where u need to declare external pin 1.
Check whether u have declared it as gpio.
Read pinsel register
