BEGINILAH TAMPILAN YANG AKAN MUNCUL :
LANGKAH PEMBUATAN :
1. BUKA MIDE-51
2. FILE NEW- KEMUDIAN TULIS KODING BERIKUT INI

end
3. SIMPAN FILE TERSEBUT DALAM FORMAT .ASM
4.BUILD PROGRAM TERSEBUT
5. BUKA TOP VIEW SIMULATOR
6.Pastikan tujuan mikrokontrolernya adalah ATMEL 89C51
7. Masuk file kemudian pilih External Modul Setting dan pilih LCD
8. Pilih 2 line x 16 karakter dan klik port line selection SEPERTI TAMPILAN BERIKUT
9. ATUR PORT SEPERTI TAMPILAN INI
10. FILE–> LOAD PROGRAM (PILIH LOKASI FILE.ASM yang tadi di buat)
11. VIEW-EXTERNAL MODULE–LCD–>> GO
SELAMAT MENCOBA.. 😀
