Great work fine. Here the final (rilevant) code:
/* Define processor and include header file. */
#define __12f675
#include "pic/pic12f675.h"
int at 0x2007 __config = _CP_OFF & _CPD_OFF & _BODEN_OFF &
_MCLRE_OFF & _WDT_OFF & _PWRTE_ON & _INTRC_OSC_NOCLKOUT;
int getValue(void)
{
int Value;
ADON =1;
GO_DONE=1;
while(GO_DONE==1)
{
};
Value = ADRESH;
ADON =0;
return (Value);
} //End ReadAdc
main()
{
TRISIO=1;
GPIO=0;
a=10;
b=25;
c=50;
for(;;)
{
valore=getValue();
v=0;
if (valore>c) v = __rosso;
else if (valore>b) v = __giallo;
else if (valore>a) v = __verde;
GPIO=v;
}
}
v.
