Question

Do a functional program in C language (please don't use C++) for CCS Compiler, PIC 18F4550

The program is not for simulation. I am going to use the PIC in a real project.

The program is for a smart (domotic) house. With the basic functions of detecting temperature, motion sensors control, lights control, open and close doors, alarm activation, passwords to activate or deactivate the alarm (using a 4x4 keyboard), etc. Everything showing related messages in a 2x16 LCD screen.

Please, give me a full explanation of the program with comments. Also, please give me the schematic diagram connections.

Explanation / Answer

#include<stdio.h>

     void main() {

    signed int a = 15, b = -12;

     int OV=0;

    asm {

      mov ax,a

      mov bx,a

      add ax,bx

      mov c,ax

     if(ah!=0)

          OV=1;

     }

      printf("%d",c);

     if(OV==1)

          printf(“overflow”)

     }
