ADC Program Help
PostPosted: Sun Jun 22, 2014 5:21 am     Reply with quote
Below is my code and I have implemented it on Proteus as well but my supply is of 5 volts so why is the serial communicator giving me absurd calculations?

Code:


#include <ADC.h>


void main()
{
   
   float value=0.0;
   setup_adc_ports(AN0_AN1_AN2_AN3_AN4_AN5);
   setup_adc(ADC_CLOCK_DIV_32);
   //Setting up PORT 1
   set_adc_channel(1);
   
   while (1)
   {
      delay_ms(300);
      value=read_adc();
      delay_us(300);
      printf("ADC Value is %f\n\r",value);
   }

}

EASY answer....please read PIC101...

Proteus is FULL of BUGS, ERRORS and Faulty DRCs..
It is a critically damaged piece of software KNOWN to NOT 'simulate' PICs properly, so how can anyone possibly, correctly debug ?

In your schematic there are at least 14 errors,any of which are fatal.

The first is the injecting of an AC signal into the PIC ADC.In the real world doing this let's the 'magic smoke' out of the PIC and turns it into pure sillycon.
