ABOUT THIS BOOK

Naturally, the first question is: “Is it possible to learn hardware, firmware, and software design

in a single, and not very thick book?”

My answer is “Yes” , plain and simple, and I will explain why. Both you and I know very well

it takes long years of hard study of each of the above design fields, and you need a lot of practice

and many supporting books to successfully accomplish those tasks. However, the first step is the

most important one; it needs to be in the right direction, and executed in the proper way. This

book is a practical design example—a good, working one!—and it covers fairly well title topics. It

represents that first, small, and the most important step.

Over the years I bought many books related to various programming languages or to hardware

design, and I always looked for the thickest ones, hoping they contain more precious knowledge.

Unfortunately, many times I was rather disappointed, and I considered myself quite lucky if two

dozens out of twelve hundred printed pages contained any useful, practical information. They are

piled now on shelves, and it is possible I will look for one or two lines of code in any of them,

during the next two or three years.

The tough reality today for writers and publishers is, the best place to find general knowledge

information is the Internet, due to the fact it allows for filtered, fast, computer search. In addition,

that information is totally free!

“ Now, wait a minute, Gino ,” you might say, “ if the Internet is the cheapest and the best place

to find information, why should I make the effort to buy your book? ”

Well, my friend, printed or electronic books you buy contain information that goes way beyond

general, basic, and free knowledge you will find on the Internet. Information was, it is, and it will

forever be the most expensive item in existence. If you are serious about learning, expect to invest

little time, efforts, and money for that, same as we all do.

Now, the problem with the available free information on the Internet comes to the readers’

advantage, because it forces Authors and Publishers to come up with competitive books that will

appeal more. Unfortunately, few books manage to do it, and that brings a bad reputation to the

trade. However, I have no doubts the readers will find this book different from any other. I am not

afraid of competition, and I believe this book I present is the best one ever in its domain. I base all

my reasons on the fact I know what is good or bad information, because I searched myself for

years, for good design books. Before being a writer, I am a voracious reader!

Learn Hardware Firmware and Software Design (LHFSD) is in fact a Design Project; an

example of how things work and are done professionally in the industry today. I will guide you

step by step through hardware, firmware, and software design, and we will build, together,

working, useful tools, with a large range of applications. In fact, this book builds a set of templates

which you will reference throughout your future design career, in personal hobby development, or

when you will decide to start building your own commercial product!

To come back to the question of learning hardware, firmware, and software design in a single

book, that is perfectly possible with good Project Management skills. By some strange turns of

events, it happened I worked all my life with prototype projects and new technologies, and I had to

execute tasks that seemed, if not impossible, at least very difficult. After many years, the difficult

tasks of the impossible type fail to impress me anymore. This book is just another technical project

for me, and the only difficult aspect is, I have to finish it within deadlines—you cannot even

imagine how tight those deadlines are. However, you, the reader, have all good reasons to doubt

my words. Just bear with me throughout the book and you will be the one to decide if I

accomplished those tasks sufficiently well or not. Do not worry: I will know your decision.

The second important question which needs to be answered is: “ What is this book about

exactly? ”

Learn Hardware Firmware and Software Design is structured in three parts, and here

follows a brief summary of their content:

Part 1, Hardware Design , is a practical schematic design: we are going to build together the

LHFSD-HCK (Hardware Companion Kit). That piece of hardware has a fair degree of complexity,

and my intention is, it will be a useful hardware tool, or instrument, good enough to burn a

dsPIC30F4011—or dsPIC30F3011—microcontroller, to test additional hardware modules, and to

quickly implement new firmware and software test programs.

We will start from a plain, blank page, and we will design the LHFSD-HCK gradually, to

include the following hardware modules:

1. The ICD2 interface needed to program and debug the firmware code;

2. The RS232 interface needed to communicate serially with the software control

applications residing on your PC;

3. One Seven-Segments three figures led display. I used multiplexing to drive those three

figures, which is an interesting hardware and firmware application to learn. In addition, the

seven-segments display is an excellent debugging tool, because it can show the integers’

values inside the hard-to-reach routines—the MPLAB ® ICD2 In-Circuit Debugger cannot

see inside all pieces of firmware code, like macros and ISR (Interrupt Service Routines).

The seven-segments module is also an excellent example of working with standard logic

ICs of the “Shift Registers” family.

4. The SPI ® Bus (Serial to Peripheral Interface) connected to three devices: serialized

Inputs ( PISO ), serialized Outputs ( SIPO ), and to a programmable digital potentiometer

working as Digital to Analog Converter ( DAC );
