help me
find in google do not have clock code of pic16f877a where not true
ask clock code for pic16f877a and pic simulation proteus
or hex file and schematic design file of proteus
below copy from youtube
| Code: |
#include <16F877A.h>
#fuses XT,NOWDT,PUT,NOBROWNOUT,NOLVP
#use delay(clock = 4000000)
#byte PORTA=0X05
#byte PORTC=0x07
#byte PORTB=0X06
#define A0 PIN_A0
#define A1 PIN_A1
#define A2 PIN_A2
#define A3 PIN_A3
#define A4 PIN_A4
