LPC1114_Timer16_0中断程序_MDK编译环境

关于Timer16_0代码：

LPC_SYSCON->SYSAHBCLKCTRL |= (1<<7); //开启定时器时钟

LPC_TMR16B0->PR=1000;//1000-1; //预分频计数器

LPC_TMR16B0->MR0=12000; //匹配寄存器

LPC_TMR16B0->TCR=0x1; //开启定时器计数器

LPC_TMR16B0->MCR=3;//(1<<0)&(1<<1); //匹配控制--匹配则引发中断并复位定时器

NVIC_EnableIRQ(TIMER_16_0_IRQn); //中断使能

Timer16_0中断程序：

void TIMER16_0_IRQHandler(void)

{

if ( LPC_TMR16B0->IR & 0x1 )

{

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

//timer16_0_counter++;

GPIOSetValue( 0, 3, 0 ); //给P0.3位写0

Delay_Ms(100);

GPIOSetValue( 0, 3, 1 ); //给P0.3位写0

Delay_Ms(100);

}

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

{

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

timer16_0_capture++;

}

return;
