Sisteme cu Microprocesoare

Controlul turatiei unui motor de c.c.

 

I. Project Description

 

 

II. Project Requirements

Pentru realizarea proiectului vom avea nevoie de urmatoarele componente:

Cod Schema	Cod piesa
R1,R6	2x 100K/0.25W
R4	1x 100R/0.25W
C3-C7	5x 1uF/50V,2x100uF
C8-C9	2x 47NF/63 V NEPOL,2x0.1uF
B1	1x PUSH BUTTON KRS1273
PIC16F628A	1x PIC16F628AI/P
MAX232	1x MAX232 CPE
LM7805	1x 7805
soclu 18 pini PIC+MAX	2x LC18
placa test 50x100 pastile	2x placa test 50x100
1 mufa DB9 TATA	2x DB9PF
1 circuit integrat	1x L293
1 motor de c.c de 9V
conectori placa	2x2pini,2x3 pini
1 conector tata alimentare
1conector mama alimentare

De asemenea avem nevoie si de un programator PIC disponibil in laborator,cu care vom incarca programul

 pentru a verifica in primul stadiu functionarea placutei PIC-ului si programul  pentru placuta EVZ, in care

prin  apasarea butoanelor "-" si "+" se va scade  ,respectiv mari turatia motorului de c.c ,si  prin apasarea "->"

,"<-"se va schimba sensul motorului,in sensul acelor de ceasornic respectiv in sens trigonometric,PIC-ul

emitand o anumita frecventa driver-ului care alimenteaza motorul.

 

III. User Flow

Un user ar putea sa maresca sau sa scada turatia motorului de c.c. prin manevrarea butoanelor "-" si "+" si sa schimbe

 sensul motorului "->","<-"  in sensul acelor de ceasornic respectiv in sens trigonometric,butoane ce se gasesc pe

tastatura placii EVZ3.

V. Hardware Design

 

 

 

Add pictures and comments about the hardware implementation. Should include any schematic used in simulation (e.g. Proteus).

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.
