hello everybody, i have a problem about an acquisition of sinus signal.
so I need the amplitude of tow signals. so I do it with the pic16f88.
this is my program.
the problem is : when i do the simation whit proteus, I do not get anything on the LCD.
so I need the amplitude of tow signals. so I do it with the pic16f88.
this is my program.
Code:
#include <16F88.h>
#device ADC=10 // conversion 10 bits
#include <math.h> //Ajoute la lib math
#fuses HS,NOWDT,NOPROTECT,NOLVP
