PIC ADC
PostPosted: Sat Mar 13, 2010 7:37 am     Reply with quote
Hello
How can I convert 10bit result of PIC16F877A ADC to BCD code or other methods to display on 7segment display?
I have written the code below to read ADC pin:
Code:

  #include <float.h>
  #include <math.h>
  #include <stdio.h>
  #include <string.h>
int32 value;
int32 value2;

void main()
{
   setup_adc_ports(AN0);
   setup_adc(ADC_CLOCK_DIV_2);
   setup_psp(PSP_DISABLED);
   setup_spi(SPI_SS_DISABLED);
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_comparator(NC_NC_NC_NC);
   setup_vref(FALSE);
   SET_TRIS_B( 0 );
   // TODO: USER CODE!!
adccheck:
{
 OUTPUT_B(0x00);
 do {
     set_adc_channel(0);
     delay_ms(50);
     value = read_adc();
     value = (((int32)value*5000)/1024)+5;
     value = value/10;
    if (value!=value2){
     printf("\r\n\nCalibrated Result = %4.2Lw",value);
    }
     value2 = value;
  }while(true);
}
}

thanks.

Look at the lcd_putd() function in this CCS example file:
