LPC1114_Timer16_0 interrupt program_MDK compilation environment-EEWORLD

About Timer16_0 code:

LPC_SYSCON->SYSAHBCLKCTRL |= (1<<7); //Start the timer clock

LPC_TMR16B0->PR=1000;//1000-1; //Prescaler counter

LPC_TMR16B0->MR0=12000; //match register

LPC_TMR16B0->TCR=0x1; //Start the timer counter

LPC_TMR16B0->MCR=3;//(1<<0)&(1<<1); //Match control--matching triggers an interrupt and resets the timer

NVIC_EnableIRQ(TIMER_16_0_IRQn); //Interrupt enable

Timer16_0 interrupt routine:

void TIMER16_0_IRQHandler(void)

{

if ( LPC_TMR16B0->IR & 0x1 )

{

LPC_TMR16B0->IR = 1; /* clear interrupt flag */

//timer16_0_counter++;

GPIOSetValue( 0, 3, 0 ); //Write 0 to P0.3

Delay_Ms(100);

GPIOSetValue( 0, 3, 1 ); //Write 0 to P0.3

Delay_Ms(100);

}

if ( LPC_TMR16B0->IR & (0x1<<4) )

{

LPC_TMR16B0->IR = 0x1<<4; /* clear interrupt flag */

timer16_0_capture++;

}

return;

}
