can mdk3.11 simulate the LPC2103 ADC interrupt?

lin li over 18 years ago

device:LPC2103 Keil MDK 3.11 I want to control the sample speed with MAT0.3 in simulator,but I can't reach the interrupt subroutine and the ADC do not work at all! Thanks everyone read the message!

the following is my code:

*******************************************************
#include <lpc2103.h>

void InitADC(void); __irq void irq_adc (void) ;

void InitTimmer(void); __irq void irq_t0 (void) ;

int main(void)
{

InitADC(); InitTimmer(); while(1); return(0) ;
}

// T0.3
void InitADC(void)
{ // SEL CKDIV PDN START

int x=0x000000ff | 100<<8 | 1<<21 |5<<24 ;

ADCR = x;

ADINTEN=0X1FF;

PINSEL0 |= 3<<20 | 3<<22 | 3<<24;

PINSEL1 |=3<<12 | 3<<14 | 3<<16 | 3<<18 | 3<<20 ;

VICVectAddr1=(long)irq_adc ;

VICVectCntl1 |= 0x20 | 18; VICIntEnable |= 1<<18;

}

void InitTimmer(void)
{ T0MCR = 3<<9;//On match reset the counter and generate an interrupt

T0MR3 = 1500; //Set the cycle time

T0TCR = 0x00000001;//enable timer

VICVectAddr0=(long)irq_t0 ;

VICVectCntl0 = 0x20 |4; VICIntEnable|= 1<<4;

}

__irq void irq_adc (void) { int adc_channal;

adc_channal=ADSTAT & 0x00ff;

switch(adc_channal)

{ case 1:break; case 2 :break; case 4 :break; case 8 :break; case 0x10 :break; case 0x20 :break; case 0x40:break; case 0x80:break; } }

__irq void irq_t0 (void) { T0IR = 1; // Clear interrupt flag

VICVectAddr = 0; // Acknowledge Interrupt

switch(T0IR) { case 1:break; case 2 :break; case 4 :break; case 8 :break; case 0x10 :break; case 0x20 :break; case 0x40:break; case 0x80:break; }

}

Thank you for looking at my threat so seriously!!

device:lpc2103 develop

tool:keil mdk3.11 simulator

function:
1.Sample voltage from AD00.

2.Sampling speed is controlled by MAT0.3

problem: can't not reach the ADC interrupt subrountine

code list:
The declaration

#include <lpc2103.h>

void InitADC(void);//initiate ADC
__irq void irq_adc (void) ;//ADC interrupt subroutine
void InitTimer(void);//initiate timmer
__irq void irq_t0 (void) ;//timmer 0 interrupt subroutine

The main function

int main(void)
{
InitADC(); //initiate ADC
InitTimer(); //initiate timer
while(1);
return(1) ;
}

ADC initiation part

 void InitADC(void)// Initate the ADC

{ // SEL=1 CKDIV=100 PDN=1 START=5(MAT0.3)
ADCR = 0x1 | 100<<8 | 1<<21 |5<<24 ;
ADINTEN=0X101;//enable interrupt of ADC
PINSEL0 |= 3<<20 | 3<<22 | 3<<24;// connect the pin
PINSEL1 |=3<<12 | 3<<14 | 3<<16 | 3<<18 | 3<<20 ;
VICVectAddr1=(long)irq_adc ;//set the interrupt adress
VICVectCntl1 |= 0x20 | 18; //set the timmer0 interrupt
VICIntEnable |= 1<<18;//enable timmer0 interrupt
}

timer initiation part

 void InitTimer(void)//Initiate the timer0
{ T0MCR = 3<<9;//On match reset the counter and generate an interrupt in MAT0.3
T0MR3 = 1500; //Set the cycle time
T0TCR = 0x00000001;//enable timer
VICVectAddr0=(long)irq_t0 ;
VICVectCntl0 = 0x20 |4; VICIntEnable|= 1<<4;
}

the ADC interrupt subrountine

// the ADC interrupt subrountine
__irq void irq_adc (void) {
int adc_channal;
adc_channal=ADSTAT & 0x00ff;
VICVectAddr = 0; // Acknowledge Interrupt
switch(adc_channal)

 { case 1:break;
   case 2 :break;
   case 4 :break;
   case 8 :break;
   case 0x10 :break;
   case 0x20 :break;
   case 0x40:break;
   case 0x80:break;
  }
}

THE timmer0 interrupt subrountine

 // THE timmer0 interrupt subrountine

__irq void irq_t0 (void) {

VICVectAddr = 0; // Acknowledge Interrupt

switch(T0IR)
  { case 1:break;
    case 2 :break;
    case 4 :break;
    case 8 :break;
    case 0x10 :break;
    case 0x20 :break;
    case 0x40:break;
    case 0x80:break;
   }

  TOIR=0XFF;

}
