Innovative Electronic System Design Projects

Abstract

Innovation is essential to bring technologies to end users at affordable prices and acceptable power/performance levels. Easy availability of low-power and high-performance integrated circuits packed with more functionalities than ever before is inspiring innovators to explore novel applications or revisit known applications with a new outlook. Game-changing technologies that have evolved in the past few years are – (a) low-power short-range low data-rate wireless communication, (b) low-cost and low-power embedded processors with considerable analog integration, (c) high-performance and low-power analog integrated circuits. The 69 papers in this book have been classified under 12 categories to assist the reader. These categories are – Assistive Technologies, Automotive Electronics, Digital Signal Processing, Internet of Things, LED Lighting, Measurement, Health Monitoring, Power Management, Robotics, Security and Safety, Solar Power, and Telecommunication. The reader can locate video demonstrations of these projects on the Internet. An important aspect about all these projects is their emphasis on finding a complete solution that involves specification, hardware design, software design and testing. While most projects attempt to prove the concept through prototyping, several projects are quite close to becoming products. These projects will be useful to students, teachers, and professionals from various disciplines – Electronics, Electrical Engineering, Telecommunication, Instrumentation, and Biomedical Electronics among others. Most of the papers included in this book were presented at the first Texas Instruments India Educators’ Conference held in April 2013.

It gives me immense pleasure to place this book in your hands. This volume consists of 69 papers, each
describing a fairly ambitious project in the area of embedded system design. The authors of all these
papers are students and their faculty mentors from Indian engineering colleges. These papers were
presented at the first Texas Instruments India Educators’ Conference (April 4-5, 2013) as regular or
poster papers. Many projects described in this book were supported as part of Texas Instruments
Innovation Challenge India Analog Design Contest (2013) under the Texas Instruments India University
Program.
The papers presented at the conference appeared in a CD-ROM version of the proceedings produced by
IEEE CPS and archived under IEEE Xplore. In this book, you will find edited versions of the papers. I have
tried to bring consistency in all the papers. I have divided the papers into 12 sections based on the
application domain of the project. Each of these sections has about six chapters. I have also included
some review questions at the end of each chapter. A reader will benefit by attempting to answer these
questions; some of the questions may lead to new projects while others will help assimilate the main
contributions of the chapter.
A common theme that runs through all these papers is the use of embedded processors and analog
integrated circuits from Texas Instruments. TI is a leading vendor of semiconductor parts. Jack Kilby
invented the Integrated Circuit at TI in 1958. Ever since, TI has maintained a leadership position in the
area of semiconductors. TI provides high performance analog ICs, power management ICs, analog front-
end solutions and catalog analog parts to meet every need in electronic system construction. TI provides
three types of embedded processors, namely, microcontrollers, microprocessors, and digital signal
processors. TI microcontrollers come in three families, namely the ultra low-power MSP430 (16-bit)
family, the C2000 real-time microcontroller family, and the TIVA ARM-based connectivity-rich
microcontroller family. TI’s Sitara microprocessors are based on ARM microprocessor cores. TI provides
many digital signal processor solutions the low-power C5000 family of processors (16-bit), the high-
performance C6000 family (32-bit, mostly symmetric multicore). TI also provides many assymetric
multicore solutions such as OMAP and Da Vinci. A single software development platform, the Code
Composer Studio, based on the Eclipse IDE, can be used across the processor families.
The distribution of papers in the twelve sections of book is as shown in the table below. The six papers
included in the section on “Assistive Technologies” describe solutions developed by academicians to
held physically challenged persons. The five papers in Section 2 discuss the use of modern embedded
processors, wireless communication and analog ICs to make driving safer. It is expected that the area of
automotive electronics will attract considerable research and development efforts in the coming years.
It is often said in the lighter vein that there is more Silicon in the modern vehicle than metal.

The “Internet of Things” (IOT) is an emerging area that promises to grow steeply over the next few
years. It is expected that the availability of sensors, cheap embedded processors and wireless
communication will allow household gadgets such as washing machines and fans to be controlled over
the Internet. You will find six papers related to IOT.
Light Emitting Diodes (LED) have gained popularity in the past few years for many reasons. They can
provide an alternate source of power-efficient lighting. LEDs can also be used in an alternate form of
telecommunication. In Section 5, you will find four papers related to LED lighting.
The field of measurements and instrumentation is being given a facelift through the use of low-power
processors, highly accurate and low-power analog circuits, and wired/wireless communication. You will
find six papers in Section 6 that describe various kinds of instruments. In Section 7, you will find eight
papers related to personal health, diagnostics, and remote health monitoring.
Section 8 includes 5 papers in the area of power management, which is becoming an area of focus by
itself. Power management is essential to cut down the energy costs and improve the reliability of the
electronic parts. Section 9 includes five papers in the area of robotics, which enjoys considerable
popularity among student population.
Six papers related to security and safety are included in Section 10. Section 11 includes 7 papers on the
topic of solar energy harvesting. Finally, Section 12 includes six papers in the area of telecommunication,
including line-of-sight communication using light emitting diodes.

While some of these papers are highly innovative, many focus on final implementation. If you look up on
the Internet, you will find YouTube videos that demonstrate the working projects. I am confident that
readers of this book will find ideas that will inspire them and make them think of further applications of
modern electronic technologies. We are living through interesting times when technologies are
available to see our ideas realized in a reasonable amount of cost and effort. Development kits such as
launchpads and boosterpacks are highly affordable and easy to use. Availability of source code and
hardware details of open source projects has also fuelled the “Do it Yourself” and “Maker” revolutions
that we are witnessing. The free IC samples program from Texas Instruments has been a great boon for
makers and innovators. The availability of discussion forums such as e2e.ti.com has also been a
facilitator in this maker revolution.
There are many ways in which you can use these projects. You can learn from them and have fun doing
similar projects. You may be inspired to become an entrepreneur. If you are a teacher, you may be
inspired to include some of these elements in your teaching and lab exercises.
