Hi, i am trying to have to adc conversion but it seems not to work. Below is my code:
#include "msp430g2553.h"
#define LED0 BIT0 //RED LED
#define LED1 BIT6 //GREEN LED
unsigned int res[2]; //for holding the conversion results
void main (void)
{
//reading voltage
WDTCTL = WDTPW + WDTHOLD; // Stop WDT
ADC10CTL1 = INCH_1 + ADC10DIV_0 + CONSEQ_3 + SHS_0; //A1/A0, multi channel repeated conversion
ADC10CTL0 = ADC10SHT_2 + MSC+ REFON + ADC10ON + ADC10IE; //2.5 reference voltage
ADC10AE0 = BIT1 + BIT0; // PIN A1 AND A0 ADC option select
ADC10DTC1 = 0x2; // 2 conversions
P1DIR &= ~(LED0 + LED1); // Set P1.0 output
for (;;)
{
ADC10CTL0 &= ~ENC;
while (ADC10CTL1 & BUSY); // Wait if ADC10 core is active
ADC10SA = (int)res; // Data buffer start
ADC10CTL0 |= ENC + ADC10SC; // Sampling and conversion ready
__bis_SR_register(CPUOFF + GIE); // LPM0, ADC10_ISR will force exit
if(res[0]<512){
P1OUT &= ~(LED0 + LED1);
P1OUT |= LED0; // LED0 is on
}
elseif(res[1]<512){
P1OUT &= ~(LED0 + LED1);
P1OUT |= LED1; // LED1 is on
}
}
}
#pragma vector=ADC10_VECTOR
__interrupt void ADC10_ISR(void)
{
//code from reading from res and sending it to AP
__bic_SR_register_on_exit(CPUOFF); // Clear CPUOFF bit from 0(SR)
}
I am a newbie to this, can anyone help me out? Thanks
