I am using LPC2368 with RTX kernel .
I need to run a timer interrupt after a specific time interval again and again as scanning’s routine. I initiate the timer to generate the interrupt.
void timer_init(void) { /* Setup Timer Counter 0: Periodic Timer with Interrupt */ T0MR0 = 1499999; /* TC0 Match Value 0 */ T0MCR = 3; /* TCO Interrupt and Reset on MR0 */ T0TCR = 1; /* TC0 Enable */
/* Setup Timer Counter 0 Interrupt */ VICVectAddr4 = (unsigned long)tc0_isr; /* TC0 Interrupt -> Vector 4 */ VICVectCntl4 = 0x02; /* TC0 Interrupt -> Priority 2 */ VICIntEnable = 1 << 4; /* Enable TC0 Interrupt */}
__irq void tc0_isr (void) {
// code here
T0IR = 1; // Clear interrupt flag VICVectAddr = 0; // Acknowledge Interrupt }
When I debug the above code.. the timer interrupt is run the first time. but not after that . What do i need to change so that the timer interrupt runs periodically again and again
Sorry about the mess here is the code
void timer_init(void){
/* Setup Timer Counter 0: Periodic Timer with nterrupt */
T0MR0 = 1499999; T0MCR =3; T0TCR = 1;
/* Setup Timer Counter 0 Interrupt */ VICVectAddr4 = (unsigned long)tc0_isr;
VICVectCntl4 = 0x02 VICIntEnable = 1 << 4;
}
__irq void tc0_isr (void){
