Project Name

 

I. Project Description

Proiectul nostru are la baza placa de uz didactic EV/Z3. Aceasta comunica prin intermediul interfetei seriale RS232 cu placa dezvoltata. Cu ajutorul unui microcontroller ATMega88 ajustarea intensitatii luminoase a  ledului cu ajutorul tastelor =>/<= de pe tastatura EV/Z3 dar si oprirea transmisiei cu ajutorul butonului Reset, aceasta ducand implicit la stingerea diodei-led.

II. Project Requirements

What does the project require to be implemented (both hardware and software). Expected behavior.

Theacher Proposal
- placa de PIC -- led 12V
- placa de Z3 trimite prin seriala intensitatea ledului.
- Soft: program de iluminat configurabil de la tastatura ( gen cum lumineaza ledul timp de x secunde)
- buton de +/- pentru intensitate - tot pe placa Z3.

 

III. User Flow

Cu ajutorul interfetei seriale RS232 placa dezvoltata comunica cu placa educationala EV/Z3. Utilizatorul placii poate trimite ledului aflat pe circuit 3 trepte de intensitate cu ajutorul sagetilor aflate pe tastatura ev/z3. Totodata de pe tastatura putem comanda oprirea transmisiei cu ajutorul tastei RESET.

IV. Required components

-Microcontroller ATMega88

-circuit integrat MAX232 care converteste semnalul de la interfata seriala RS 232

- rezistente( 10k, 470 ohmi ) si condensatoare(4x1uF, 2x22pF, 3x10pF, 1x100nF )

-led

-cristal de cuart 20mhz

-conexiune de alimentare

-baterie 9V

-fir conector


V. Hardware Design

Schema circuitului

VI. Software Design

Describe the software functionality of your project, including code used on EV/Z3 board and the uC board. Discuss your algorithms, data flows and so on. Should post code samples of the most interesting bits.

VII. Results

Data about the final project implementation. Includes screenshots, movies, comments about your project in action.

VIII. Download

After you have presented your project at the laboratory (week 13-14) you will add all your sources here. Any hardware simulation used, code archive and so on.

IX. Status

You will have to update this every 2 weeks to include details of what you have done on your project. E.g.: aquired componets, made board, written code for EV/Z3

X. Personal Contribution

In case 2 or more students were involved, this section will contain what each student has done for the project. You will be asked when presenting project and graded individually on this.
