1 Cara Penggunaan Kit MCS51 File-file yang diperlukan: 1. usbasp-windriver ProgISP ver MIKROC 8051 ver 2.2 : untuk anda yang menggunakan bahasa C 4. ASM51: untuk anda yang menggunakan bahasa assembler Langkah-langkah pemrograman kit Evaluation Board Mikrokontroler MCS51 (AT89S52): 1. Hubungkan Konektor ISP Downpoder ke Programmer USBAsp Susunan pin ISP pada Kit Evaluation Board Mikrokontroler AVR ATMega16 GND RST SCK MISO MOSI VCC Hubungkan pin ISP pada Kit Evaluation Board Mikrokontroler MCS51 dengan pin ISP USBasp GND---GND RST---RST SCK---SCK

2 MISO---MISO MOSI---MOSI VCC---VCC Gambar koneksi USBasp programmer degan kit mikrokontroler Langkah-langkah instalasi UsbAsp downloader : 1. Pasang USB downloader 2. Install window driver usbasp-windriver Cek dengan device manager, harus muncul USBasp Contoh : Pakai Bahasa C Program: Buat program pakai mikroc PRO for 8051 untuk bahasa C, jika pakai bahasa assembler bisa pakai notepad, kemudian compile pakai ASM51

3 Klik menu Build, untuk mengubah jadi file hex, Kemudian setelah di build, jadi file hex, masukan ke IC mikrokontroler AT89S52 menggunakan USBasp programmer dan program Progrisp, seperti gambar dibawah Untuk tipe IC, pilih AT89S52, lalu Pilih File load Flash, cari file hexnya, terus pilih tombol Auto

4 ================================================================================== Pemrograman MCS51 (AT89S51,52 dll) dengan Bahasa C Software yang digunakan dalam ujicoba kali ini ialah MIKROC 8051 ver 2.2. pemrograman mikrokontroler AT89S51 dengan bahasa C memang lebih mudah jika dibandingkan dengan menggunakan Assembler. apalagi jika kita ingin membuat perangkat yang rumit akan sangat terasa perbedaannya. Berikut merupakan daftar uji coba tersebut: 1. Percobaan LED Skema Uji Coba LED Program LED 1 menyalakan Led dengan bilangan heksa P0=0x00; // LED SEMUA ON

5 Program LED 2 menyalakan sebagian Led dengan bilangan heksa P0=0xF0; // LED P0-P3 ON Program LED 3 menyalakan 1 Led dengan bilangan biner P0=0b ; // LED 1 ON Program LED 4 menyalakan 2 Led dengan bilangan biner P0=0b ; // LED 1 dan 8 ON Program LED 5 menyalakan Led per bit P0_0_bit=0; // LED 1 ON P0_7_bit=0; // LED 8 ON Program LED 6 Blinking led dengan delay while(1){ P0=0b ; //led ON delay_ms(1000); //tunda 1 detik P0=0b ; //led OFF delay_ms(1000); //tunda 1 detik 2. Percobaan Switch

6 Skema Uji Coba Switch Program Switch 1 while(1){ if(p1_0_bit==0){p0=0x00; //jika tombol 1 ditekan LED ON Program Switch 2 while(1){ if(p1_0_bit==0){p0=0x00; //jika tombol 1 ditekan LED ON if(p1_1_bit==0){p0=0xff; //jika tombol 2 ditekan LED OFF Program Switch 3 while(1){ if(p1_0_bit==0){p0_0_bit=0; //jika tombol 1 ditekan LED 1 ON if(p1_1_bit==0){p0_1_bit=0; //jika tombol 2 ditekan LED 2 ON if(p1_2_bit==0){p0=0xff; //jika tombol 3 ditekan LED OFF Program Switch 4 while(1){ if(p1_0_bit==0){p0=0x00; else{p0=0xff; //jika tombol 1 ditekan led on dilepas led off 3.
