problem regarding timer0 in the lpc2378

jithendranath swamy

Hi i am currently working on the mcb2300.
the timer0 is used.Iam just toggling the led ports.In the simulation i am able to get the output but regarding the hardware i am not able to see the toggling of the led's.

Here i am posting the code snippet.kindly help me to solve the problem.

Thanks in advance....


#include<stdio.h>
#include <LPC23XX.H>

void T0isr(void);
void time_init(void);
void delay(void);
unsigned int value;
void led_init(void);
void delay(void);

int main(void)
{
PLLCON=0x00;
CLKSRCSEL=0x01;
CCLKCFG=0x03;
PCONP=0x00000002;

time_init();

T0PR=0x0000C6C0;
T0TCR=0x02;
T0MCR=0x0003;
T0MR0=0x00000005;
T0TCR=0x01;
//T0CR0=0x01;
T0TC=0x00;
//T0CTCR=0x00;
T0PC=0x00;

FIO2DIR=0x000000FF;
FIO2MASK=0x00000000;
FIO2SET=0x00000055;
FIO2CLR=0x000000AA;

T0IR=0x01;
VICVectAddr4 = (unsigned)T0isr;

VICVectPriority4=0X00000024;

//Enable the interrupt
VICIntEnable |= 0x00000010;

while(1);

}

void time_init()
{

PCLKSEL0=0x0000000C;
PINSEL3=0x03000000;
PINMODE3=0x00000000;

}

void T0isr(void)
{
FIO2CLR = 0x000000AA;
FIO2SET = 0x00000055;

T0IR |= 0x00000001;

//Dummy write to signal end of interrupt
VICVectAddr = 0x00000000;
}
