Percobaan 5.4. Kalibrasi dataADC ke suhu dengan menggunakan metode Look Up Table.

Kenapa kita membutuhkan look up table?: Look up table adalah suatu cara yang digunakan untuk menghindari proses perkalian dan pembagian yang bertele-tele dan memusingkan bila dilakukan dengan menggunakan bahasa assembly, yang tentunya harus dilakukan bila kita akan kalibrasi suatu alat ukur. Contoh kalibrasi Termometer dengan menggunakan persamaan persamaan berikut ini: Suhu = DataADC * 100/ 255 oC.
Contoh table untuk konversi data ke besaran suhu ( dengan menggunakan program Microsoft Excell ). Karena data decimal maksimal adalah 255 dan suhu maksimal 100 maka Data look up tablenya adalah 255/100.

Pada percobaan 5.4, kalibrasi dilakukan untuk perubahan range desimal (0 s/d 255) menjadi range suhu(000.0 s/d 100.0 oC)

1. Pada saat langkah pemrograman posisikan saklar togle ke posisi PROG
2. Posisikan saklar togle ke RUN untuk mengaktifkan ADC0804 CS=0
3. Hubungkan modul Microcontroller Trainer dengan power supply +5V
4. Hubungkan modul Microcontroller Trainer dengan rangkaian programmer
5. Buka Program M-IDE Studio for MCS-51, sebagai editor dan compiler program (download file prog54a.asm)
