Title and Introduction

[email protected]

Introduction:

The purpose of designing and development of multifunctional PIC microcontroller based trainer is

to design such embedded system trainers which have different functions modules to be used forteaching and learning on one board.

It will help the students of engineering and technical education to get in depth knowledge and

practical hands on experience about programming and implementation of PIC microcontroller in

various embedded systems applications.

On very affordable price, students may even place this trainer board in their home made labs

especially for technical education students trainings ,the trainer to be developed would support the

good process of learning.

This PIC trainer consist of ten on-board embedded modules including main board and

programmer, and experimental Lab manuals for all embedded modules.

The current curricular in technical universities and institutions are more theoretical

rather than technical hands-on based, thus producing graduates who are unable to

meet the ever-rising demand of industry for skilled engineers.

The employment cost isultimately increased, as the employers have to spend extra

on providing the required training.

The emphasis in the light of education policy is to have more hands-on practical

rather than academic.

The price range for fully equipped workstations that comes complete with

microprocessor or microcontroller training kits is very high and also additional costs

such as maintenance of the board should be taken into account.

This contributes to the limited number of boards and the ratio of available board to

the students in the lab come to be very high 1:2 or 1:3, which may depreciate the

effectiveness of the teaching and learning process, consequently, the time taken to

complete the whole syllabus will lengthen and probably the objective of the module

taught will not be achieved.

Most of the technical courses are being taught by using modules, that are prepared

by vendors with mostly low academic background. Hence, such modules are

produced with fixed features and usually have constraints in adapting to the

changing needs of a technical institution.

Problem Statement

The objective of this Project is:

To design a PIC based educational trainer that can support the teaching

and learning of Microprocessor System or Embedded System Design.

To integrate several embedded modules in one training board to facilitate

the learning environment for the students of technical education.

To provide the students with an opportunity to be familiar with software

tools like compilers, simulators, chip programming software.

To provide a high degree of flexibility of use, which will allow the

trainer/lab board to be used in varying applications.

Objective

PIC Trainer to be developed should support the decent process of

learning and teaching, students can also bring this trainer from their labs

and continue work at their own places.

This project serves as a fundamental for the students to indulge actively

in the development of embedded system

It is intended that the module designed should be free from any firmware,meaning that it should be open to any program and configuration without

having any firmware that could interfere with user programs.

The best thing is that the development of the programs, compiling, and

then the simulations are all carried out with the freely available software

tool Microchip MPLAB.

PIC Education Trainer for students is the best way to help the students

improve their skills and in the meantime reducing the cost for universities.

Scope and Limitation

The theoretical framework that will be used in the study is the Input-

Process-Output Model. In the IPO model, a process is viewed as a

series of boxes (processing elements) connected by inputs and

outputs. Information or material objects flow through a series of tasks

or activities based on a set of rules or decision points.

Operational Definition

[email protected] 3

There are many steps involved in the design and development of this

training panel. The panel includes, one main PIC board which is

integrated with various multi-functional embedded system modules.

All the modules are prototyped, PIC Simulator IDE is used to simulate

the interface between the target microcontroller and certain available

module . Then, modules are also constructed on a breadboard and

tested. The successful modules are then prototyped on a printed circuit

board. Finally all the modules together with its running board are

integrated and tested for their functionality.

PIC microcontroller main board is the heart of this panel. It acts as the

main processing units for all inputs and outputs. Various multi-

functional embedded system modules are being controlled using C-

language programming which is downloaded in the microcontroller.The modules are multi-functional and hence they are flexible in their

operation, which can be modified using programming.

Hardware component's of PIC Microcontrollers:PIC microcontroller production counts are in the billions per year, and the controllers

are integrated into many appliances we have grown used to, like household appliances

telecommunication, automotive industry, aerospace industry, industrial automation.

hardware can be classified as input or output. Inputs range from simple switches to

complex analog sensors which measure physical values and (ultimately) convert them

into a corresponding voltage. Outputs encompass primitive LEDs as well as

sophisticated actuators.

Switch/Button : The button is one of the simplest input elements. It consists of two

contacts which are connected if the button is pressed. So if one of the contacts is

connected to for example GND and the other is connected to the microcontroller input

and to VCC through a pull-up resistor (either internally by the microcontroller.

Matrix Keypad: The matrix keypad consists of several buttons which are arranged in a

matrix array.

Potentiometer: Thepotentiometer is a variable voltage divider. It has three pins: Two

for the input voltages Ua and Ub, one for the output voltage Uz. Depending on the

position of a turning knob, Uz is somewhere within [min{Ua, Ub}, max{Ua, Ub}]. The

correlation between the position of the knob and Uz can be either linear or logarithmic.

Hardware component's of PIC Microcontrollers:

LED: The LED (light emitting diode) is the most basic output element. Its form andcolor vary widely to accommodate a wide variety of applications. The color of a LED is

determined by the chemicals used for it. Common colors are red and green, but yellow,

orange, blue and white LEDs are also readily available, as well as LEDs emitting light in

the infrared or ultraviolet bands.

Numerical display: A seven-segment display (SSD), or seven-segment indicator, is a

form of electronic display device for displaying decimal numerals that is an alternative

to the more complex dot-matrix displays. Seven-segment displays are widely used in

digital clocks, electronic meters, and other electronic devices for displaying numericalinformation.

Motors: Electric motors use electric energy to achieve a rotary motion. There are two

basic principles which are used to create rotary motion in electric motors: the Lorentz

force and magnetic attraction.

DC Motor: DC motors use DC voltage to achieve rotary motion. They have two pins

with which to control the speed and direction of their rotary motion.

A stepper motor is a brushless, synchronous electric motor that converts digital

pulses into mechanical shaft rotation. Every revolution of the stepper motor is divided

into a discrete number of steps, in many cases 200 steps, and the motor must be sent a

separate pulse for each step.

PIC Based: The main advantages of using the PIC are low external partcount, a wide range of chip sizes (now from 5-pin up!) available, nice

choice of compilers (assembly, C++, BASIC, etc.) good wealth of

example/tutorial source code and easy programming. Once bought, the

PIC's program memory is empty, and needs to be programmed with code

(usually HEX files) to be usable in a circuit. Those trainers they controller

by PIC architecture they have very good outcomes and results becausethey are very efficient for educational and training on-board modules.

PID Based: The basic function of a controller is to execute analgorithm (electronic controller) based on the control engineer's input

(tuning constants), the operators desired operating value (set point) and

the current plant process value. They are expensive trainers and only

cover some specific operation and not interface with any module.

PLC Based: PLCs based trainers are used in many industries andmachines. Unlike general-purpose computers, the PLC is designed for

multiple inputs and output arrangements, extended temperature ranges,

immunity to electrical noise, and resistance to vibration and impact.

These trainers are used for industrial robotics and automation.

Microcontrollers: Microcontrollers may use four-bit words andoperate at clock rate frequencies as low as 4 kHz, for low power

consumption. They will generally have the ability to retain functionality

while waiting for an event such as a button press or other interrupt;

power consumption while sleeping may be just Nano watts, making

many of them well suited for long lasting battery applications. Other

microcontrollers may serve performance-critical roles, where they may

need to act more like a digital signal processor (DSP), with higher clockspeeds and power consumption.

The selected modules designed should come with open input/output

that are free to be interfaced or ported to any type of microcontrollers.

But, due to simplicity, only few microcontrollers are chosen

PIC16F84A and PIC16F877.

Before all the modules are prototyped, PIC Simulator IDE Version

5.22 is used to simulate the interface between the targetmicrocontroller and certain available modules. The modules are also

constructed on a breadboard and tested.

The successful modules are then prototyped on a printed circuit board.

Finally all the modules together with its running board are integrated

and tested for their functionality.
