I'm still a beginner in programming and I really need your help. I'm using a msp430f2274 for my project: to convert an ECG signal to digital one using ADC on msp430 and view the data as a graph in CCS and I'm not really sure how to do the graph. Below is my code :
#include <msp430.h>
// Global variables
unsigned int ADC_value=0;
// Function prototypes
void ConfigureAdc(void);
void main(void)
{
{
WDTCTL = WDTPW + WDTHOLD; // Stop WDT
BCSCTL1 = CALBC1_1MHZ; // Set range DCOCTL = CALDCO_1MHZ;
BCSCTL2 &= ~(DIVS_3); // SMCLK = DCO = 1MHz
P2SEL |= BIT4; // ADC input pin P2.4
ConfigureAdc(); // ADC set-up function call
__enable_interrupt(); // Enable interrupts.
while(1)
{
__delay_cycles(1000); // Wait for ADC Ref to settle
ADC10CTL0 |= ENC + ADC10SC; // Sampling and conversion start
__bis_SR_register(CPUOFF + GIE); // Low Power Mode 0 with interrupts enabled
ADC_value = ADC10MEM; // Assigns the value held in ADC10MEM to the integer called ADC_value
}
}
}
// ADC10 interrupt service routine
#pragma vector=ADC10_VECTOR
__interrupt void ADC10_ISR (void)
{
__bic_SR_register_on_exit(CPUOFF); // Return to active mode }
}
// Function containing ADC set-up
void ConfigureAdc(void)
{
ADC10CTL1 = INCH_4 + ADC10DIV_3 ; // Channel 4, ADC10CLK/3
ADC10CTL0 = SREF_0 + ADC10SHT_3 + ADC10ON + ADC10IE; // Vcc & Vss as reference, Sample and hold for 64 Clock cycles, ADC on, ADC interrupt enable
ADC10AE0 |= BIT4; // ADC input enable P2.4
}
