Lpc2000

Hello group,

I have one problem in capture of PWM, i.e, sometimes exist missing the
capture of PWM.
I'm using the LPC2129!! 

My interrupt function is the following  




void capture (void) {

	
	if(T1IR & TIR_CR0I){		//interrupt no chanel0 (eixo dos xx)
	   T1IR = TIR_CR0I;	   
	   
	   acel_cap_eixo_x();


	}

	if(T1IR & TIR_CR1I){		//interrupt no chanel1 (eixo dos yy)
	   T1IR = TIR_CR1I;	   

	   acel_cap_eixo_y();


	}

	if(T1IR & TIR_CR2I){		//interrupt no chanel2 (eixo dos zz)
	  T1IR = TIR_CR2I;		//clear flag interrupt	   
	  acel_cap_eixo_z();


	}

	VICVectAddr = 0xFFFFFFFF;
}


void acel_cap_eixo_x(void){
   u32 tpu; 

	if(IOPIN0 & ACEL_asc_x){	//verify if rising edge
	   tpu=T1CR0;
	   INS_ACEL_write(0, ((ACEL_T2_x-ACEL_T1_x)<<12)/(tpu-ACEL_T1_x));
	   ACEL_T1_x=tpu;
		
	}else{				//falling edge
	   ACEL_T2_x = T1CR0;
	}
return;
} 



Someone has some suggestion for this problem!!!


Thanks
      Domingos
