最近在学430，但是总遇到这样那样的问题，还请各位多多指点啊～～
#include "msp430x21x2.h"
void Delay(unsigned short time);
unsigned int ad_value[3];
void main()
{
WDTCTL = WDTPW + WDTHOLD; // Stop WDT
ADC10CTL0 = SREF_1+REFON+REF2_5V+ADC10SHT_2 + MSC+ADC10ON+ADC10IE; // ADC10ON, interrupt enabled
ADC10CTL1 = INCH_2+CONSEQ_1;
ADC10DTC1 = 0x03; // 3 conversions
ADC10AE0 |= 0x07; // P2.2,1,0 ADC10 option select
P1DIR =0X01;
Delay(1);
while(1)
{ //P1OUT |=0X01;
ADC10CTL0 &= ~ENC;
while (ADC10CTL1 & BUSY); // Wait if ADC10 core is active
ADC10SA = (unsigned int)ad_value+1;
// Data buffer start
ADC10CTL0 |= ENC + ADC10SC; // Sampling and conversion start
__bis_SR_register(CPUOFF + GIE); // LPM0, ADC10_ISR will force exit
if(ad_value[0]>0)
P1OUT |=0X01;
}
}
#pragma vector=ADC10_VECTOR
__interrupt void ADC10(void)
{
_BIC_SR(CPUOFF); // Clear CPUOFF bit from 0(SR)
}
void Delay(unsigned short time)
{
unsigned short i, j;
for(; time > 0; time--)
{
for(j = 0; j < 10; j++)
{
for(i = 0; i < 100; i++);
}
}
}
这是自已弄的一小段程序，想用数组把转换的数据读出来，数组的首地址送给ADC10SA，不知这样可对 ADC10SA = (unsigned int)ad_value+1;现在就是数组里面读不出东西，请各位帮着分析下，哪里出了问题的～～～
