    Chưong trình giao tiếp PIC với SIM300

    em copy trên mạng về được chương trình này nhưng không hiểu ý nghĩ chương trình thế nào. các pro nào có thể giải thích giúp e đoạn code này không ?
    Code:
    #include <16f877a.h>
#device pic16f877a*=16adc=10
#include <string.h>
#fuses NOWDT,XT,PUT, NOPROTECT, NODEBUG, NOBROWNOUT, NOLVP
#use delay(clock=4000000)
#use fast_io(d)
#use fast_io(b)
#use fast_io(c)
#use fast_io(a)
#use fast_io(e)
#byte porta=0x05
#byte portb=0x06
#byte portc=0x07
#byte portd=0x08
#byte porte=0x09
#bit  RS=PORTE.0
#bit  RW=PORTE.1
#bit  E=PORTE.2
#bit c0=portc.0
#bit c1=portc.1
#bit c2=portc.2
#bit c3=portc.3
#bit c4=portc.4
#bit c5=portc.5
#bit b0=portb.0
