Hi,
I need you help with my code, because the ADC value converted is half of my full int (1024 @ 5V).
My code is the next one:
Main code
| Code: |
#include "dspic_ADC_2khz_v1.1.h"
//Includes
#include <float.h>
#include <math.h>
#include <stdlib.h>
#include <string.h>
//Asignación de bits
#BIT FORM8=0x02A0.8 //bit 8 modo de adquisición de ADC
#BIT FORM9=0x02A0.9 //bit 9
#BIT ASAM=0x02A0.2 //BIT DE CONFIGURACIÓN DE AUTO INICIO DE MUESTREO
// #BIT SIMSAM=0x02A0.3//bit 3 del registro de memoria ADCON1 para muestreo simultáneo
// #BIT CHPS0=0x02A2.8 //bit 8-9 del registro de memoria ADCON2 para muestreo simultáneo
// #BIT CHPS1=0x02A2.9 //de los canales CH0 y CH1
#BIT ADIF=0x0084.11 //BANDERA DE SOLICITUD DE INTERRUPCIÓN ADC
// #BIT ADIE=0x008C.11 //HABILITA INTERRUPCIÓN ADC
#BIT SSRC7=0x02A0.7// COMPARADOR GP DEL TIMER 3 (BIT2)
#BIT SSRC6=0x02A0.6// (BIT1)
#BIT SSRC5=0x02A0.5// (BIT0)
#BIT ADON=0x02A0.15// ARRANCA CONVERSOR ADC
#BIT TON=0x0104.15 //ARRANCA TIMER 3
#use rs232(UART1A,baud=9600,parity=N,bits=8)
//variables
int16 valor;
float valor_conv;
#int_ADC1
void ADC1_isr(void)
{
ADIF=0; // Borrar bandera solicitud interr. AD
valor=read_adc(); // Tomar valor convertido
printf("%i\r\n",valor);
}
void main()
{
setup_spi( FALSE );
setup_adc_ports(sAN0 | sAN1 | sAN2 | VSS_VDD);
setup_timer2(TMR_DISABLED |TMR_DIV_BY_1 ,0);
setup_timer4(TMR_DISABLED |TMR_DIV_BY_1 ,0);
setup_timer3(TMR_INTERNAL |TMR_DIV_BY_8 ,12);
setup_timer5(TMR_DISABLED |TMR_DIV_BY_1 ,0);
// set_timer3(0x000);
setup_wdt(WDT_OFF);
setup_timer1(TMR_DISABLED);
enable_interrupts(INTR_GLOBAL);
SSRC7=0; // T3 inicia conversion
SSRC6=1;
SSRC5=0;
FORM8=0;
FORM9=0;
ASAM=1; // Inicia muestreo en fin de conversion
set_adc_channel(0); // Muestrea canal AN0
// Configurar interr., arrancar T3 y AD
ADIF=0; // Borrar bandera solicitud interr. AD
enable_interrupts(INT_ADC1);
ADON=1; // Arrancar conversor AD
TON=1; // Poner T3 en marcha
while(1)
{
}
}

If you can help me, very thank!!
