3. Introduction To Embedded
System
An embedded system is a computer system with a dedicated
function within a larger mechanical or electrical system, often
with real-time computing constraints.
It is embedded as part of a complete device often including
hardware and mechanical parts. Embedded systems control
many devices in common use today.
Ninety-eight percent of all microprocessors are manufactured as
components of embedded systems.

6. Arduino
Arduino is a prototype platform (open-source) based on an easy-to-use
hardware and software.
It consists of a circuit board, which can be programmed (referred to as a
micro-controller ) and a ready-made software called Arduino IDE
(Integrated Development Environment), which is used to write and
upload the computer code to the physical board.

7. The key features are
Arduino boards are able to read analog or digital input signals from
different sensors and turn it into an output such as activating a motor,
turning LED on/off, connect to the cloud and many other actions.
You can control your board functions by sending a set of instructions to the
micro-controller on the board via Arduino IDE (referred to as uploading
software).
Unlike most previous programmable circuit boards, Arduino does not need
an extra piece of hardware (called a programmer) in order to load a new
code onto the board. You can simply use a USB cable.
Additionally, the Arduino IDE uses a simplified version of C++, making it
easier to learn to program.
Finally, Arduino provides a standard form factor that breaks the functions
of the micro-controller into a more accessible package.

8. Board types
Various kinds of Arduino boards are available depending on different
micro-controllers used. However, all Arduino boards have one thing in
common: they are programmed through the Arduino IDE.
The differences are based on the number of inputs and outputs (the
number of sensors, LEDs, and buttons you can use on a single board),
speed, operating voltage, form factor etc. Some boards are designed to
be embedded and have no programming interface (hardware), which
you would need to buy separately. Some can run directly from a 3.7V
battery, others need at least 5V.

Arduino boards based on ATMEGA32u4 micro-controller
Arduino boards based on ATMEGA2560 micro-controller

9. Arduino uno
We will study the Arduino UNO board because it is the most popular
board in the Arduino board family. In addition, it is the best board to
get started with electronics and coding. Some boards look a bit
different from the one given below, but most Arduino have majority of
these components in common.

11. Description of board
❑ Pin1 - Power USB - Arduino board can be powered by using the USB cable from your
computer. All you need to do is connect the USB cable to the USB connection (1).
❑ Pin2 - Power (Barrel Jack) - Arduino boards can be powered directly from the AC
mains power supply by connecting it to the Barrel Jack (2).
❑ Pin3 - Voltage Regulator - The function of the voltage regulator is to control the
voltage given to the Arduino board and stabilise the DC voltages used by the
processor and other elements.
❑ Pin4 - Crystal Oscillator - The crystal oscillator helps Arduino in dealing with time
issues. How does Arduino calculate time? The answer is, by using the crystal
oscillator. The number printed on top of the Arduino crystal is 16.000H9H. It tells us
that the frequency is 16,000,000 Hertz or 16 MHz.
❑ Pin5 - Arduino Reset - You can reset your Arduino board, i.e., start your program from
the beginning. You can reset the UNO board in two ways. First, by using the reset
button (17) on the board. Second, you can connect an external reset button to the
Arduino pin labelled RESET (5).

13. Raspberry Pi
It is a single-board computer inspired by 1981 BBC Micro.
Developed in the UK by the Raspberry Pi Foundation, commercially
launching in 2012
Credit Card sized
Plugs into a TV or monitor

14. Raspberry Pie
❑The “Raspberry” derives is an homage to early computer companies
being named after fruit, like Apple, Tangerine Computer Systems,
Apricot Computers, and Acorn (which inspired the microcomputer’s
design). The “Pi” derives from the original idea to make a small
computer to run only the Python programming language.
❑The first commercially available Raspberry Pi unit was launched on
February 19, 2012, and sales started ten days later. This version
could run Linux-based desktop operating systems, and featured 256MB

34. Specifications

35. MSP430

36. MSP430 Development
hardware
The MSP430 contains several families, from the
low cost Value family to the most advanced
F6xx family. Each family is usually targeted at a set
of applications and contains a certain mix of
peripherals. In a family, however, devices vary as
far as the amount of Flash and RAM available.
It is not unusual to develop using relatively large
devices in a family, only to migrate down to reduce
costs. Because of this, the tutorial will end up
discussing several platforms, but will attempt to
cover the lowest denominator first to make it
accessible.
The MSP430 Launchpad is the most accessible
MSP430 platform and although the devices
supported do not have all the peripherals of some
of the mode advanced MSP430, it does cover so
many peripherals that it makes it an ideal platform
for starting.

37. MSP430 Development
hardware
➢ The MSP430 Launchpad is an easy way to get started with the MSP430.
For a long time the board was sold at a promotional cost of $4.30,
although it’s now available for $9.99. Still, the cost makes it difficult to
say no. You can get one from TI’s Website.
➢ The board contains a DIP socket capable of accepting most variants of
the MSP430Gxx family. The most common device used is the
MSP430G2553, which is a part running up to 16MHz with 16kB of flash
and 512B of RAM. The USB connectivity on the board allows both
programming with the on-board JTAG programmer, as well as UART
communications for data transfer.
➢ The board can be augmented with booster packs designed by TI and
third parties that enable Wireless Communications, Wi-Fi, Batteries,
Displays, and other elements.

40. MSP430 block diagram

41. MSP430F5529 Launchpad
This MSP430F5529 Launchpad is one
of the latest Launchpads. The F5529
along with the F55xx family integrate a
USB Controller, opening the door to
new applications and possibilities
previously requiring a dedicated USB to
UART converter. For a price of $12.99
you get an MSP430 that can go up to
25MHz, has 128kB of Flash and 8kB of
RAM. With USB you can implement
CDC, HID and MSC classes so you
can be a serial port, a mouse or act as
an SD card.
This board uses the same form factor
as the classic MSP430 Launchpad, so
booster boards can be reused.

42. MSP4305438 Experimenter
Board
The MSP430F5438 and MSP430F5438A are
quite popular devices due to the fact that they
have 256kB of flash. Being some of the largest
MSP430 devices makes them ideal for
prototyping to support a wide range of
applications. Some of the features of the board:
100 pin socket enabling quick insertion and
removal of devices
Dot-Matrix LCD with Backlight
Audio Jack output with on-board Audio Amplifier
3-Axis Analog Accelerometer
5 position Joystick for navigation
EM Connector headers supporting TI Low
Power Transceiver Modules

43. EZ430-RF2500 Kit
Designed as a USB Stick, it is one of the most popular kits available
from TI for those looking to try the MSP430 with a Wireless
Transceiver. This inexpensive kit allows you to start using the
CC2500 transceiver, a 2.4GHz radio that has become quite popular,
especially given the kit’s $49 price.
One side of the stick contains the FET programming circuitry allow
Spy-Bi-Wire communications with the MSP430 for debugging. The
other contains the MSP430F2274 with the CC2500 and all circuitry
needed for a connection. The MSP430F2274 is a relatively small
device, 32kB of Flash and 1kB of RAM, so applications can be
limited (especially by the RAM). Out of the box demo shows
connecting the EZ430-RF2500 wirelessly to monitor temperature and
voltage

44. JTAG Programmer
Programming, Debugging and Flashing the MSP430 is done via the
JTAG interface, or its pin reduced version called Spy-Bi-Wire.
Although this JTAG is based on the IEEE 1149.1 Joint Test Action
Group (JTAG) specification, TI has made modifications which mean
that a MSP430 specific programmer must be used. The USB-FET
is probably the most common programmer. A parallel port version
was once available but has since become extinct given the
disappearance of parallel ports and the emergence of USB.
The USB FET programmer is supported by practically all compilers
and IDEs, including Code Composer Studio, IAR Workbench and
Open source tools. The USB-FET programmer can be purchased
from TI.
