HỎi vỀ pic

[tvnghia91]

các bạn chỉ dùm mình vấn đề này với : mình làm mạch tính suất liều dùng pic 16f877a, f =4mhz, code mình viết xong rồi, kiểm tra không có lổi, nhưng khi chạy mô phỏng thử thì nó không chạy. các bạn ai biết do chổ nào thì giúp đở mình với

CODE:

#include <16F877A.h>
#device adc=8

#FUSES NOWDT //No Watch Dog Timer
#FUSES XT //Crystal osc <= 4mhz
#FUSES NOPUT //No Power Up Timer
#FUSES NOPROTECT //Code not protected from reading
#FUSES NODEBUG //No Debug mode for ICD
#FUSES NOBROWNOUT //No brownout reset
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#FUSES NOCPD //No EE protection
#FUSES WRT_50% //Lower half of Program Memory is Write Protected

#use delay(clock=4000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bi ts=8)
