No full textDewasa ini,komputer telah menjadi suatu bagian yang umum
dalam masyarakat.Dalam Pemakaiannya,komputer seringkali
dihubungkan dengan peralatan Luar.
Untuk berhubungan dengan peralatan luar,komputer memerlukan
adanya interface,Interface yang umum digunakan saat ini
adalah PPI (Progrannable Peripheral Interface)8255.
PPI 8255 adalah suatu piranti Progrannable l/O vang bersifat
paralel dalam proses Pengiriman dan pembacaan data.
menggunakan piranti 8255 berarti harus nengetahui keadaan
dari piranti tersebut, Apakah piranti 8255 dalam keadaan
rusak atau baik pada Proses pengiriman atau pembacaan data.
Untuk nengatasi masalah tersebut,maka dibuat suatu alat yang
dapat mempermudah pengujian keadaan piranti 8255.
Dan untuk memberi kemudahan dan penahanan penggunaan
piranti 8255,maka pada Tugas Akhir ini membuat suatu alat
untuk mempermudah Penguiian piranti 8Z55 dan alat untuk
memberi kemudahan penahanan nengenai piranti 8255.
Metode yang digunakan dalam penyusunan tugas akhir ini
meliputi studi Iiteratur,perencanaan rangkaian
berdasarkan studi Iiteratur,Pembuatan alat antara lain:
rangkaian decoder alamat,decoder PPI,rangkaian pengendali
PPI yang diuji dan program yang digunakan berupa bahasa
pemrograman Pascal,dan proses pengukuran dan pengujian
Berdasarkan percobaan dan pengujian yang telah dilakukan
pada tugas akhir ini,dapat ditarik kesimpulan bahwa modul
tester PPI 8255 adalah alat vang dapat digunakan untuk
nenguii keadaan dari PPI 8255 dengan cepat.
Dan modul trainer dapat memberi kemudahan pemahaman proses
pengiriman dan pembacaan data pada PPI 825
A simulator for 8255 programmable peripheral interface experiments
No full textKişisel bilgisayarlarda, 8255 programlanabilir arabirim elemanı ile paralel port giriş/çıkış deneylerinin yapılması için geliştirilmiş bir deney setinin simülatorü tasarlandı. Simulator de, 8088 mikroişlemcisi ile 8255 programlanabilir arabirim elemanında mod0 ve mod1 için çeşitli deneyler yapılmaktadır.A parallel port I/O experiments simulator was designed that had been implemented using 8255 PPI an earlier study. The simulator allows to make different experiments for mod0 and mod1 operations of the 8255 with 8088 microprocessor
Use of Parallel Port and Ic 8255 as Safety House
No full textIn a series of parallel port utilization and IC 8255 as a safety house consists of threemain blocks include: Personal Computers, PPI 8255, lamp indicator.On the use of parallel port to be controlled by IC 8255 from a software program,which is software that contains the control word is sent by the CPU to the IC 8255. ineach control block receives commands from the signal read / write and "ControlWord". where the use of parallel port is used as output ports A, B and C are used asinputs are used as output, so lower PPI8255 can work on the mode 0. except on theeasiest mode, it has no signal source prokol for one or the other two modes.In 8255 LPT circuit requires power supply +5 V / 200mA. The power supply can begot from outside the circuit or by tapping the power supply +5 V from the computer.on the use of resistors in the circuit Rp3 it's useful to keep the data bus = 0. while forthe capacitor C5 and C6 serve to secure the WR and RD from the noise
