This document details the software which needs to be installed on the host computer before taking the tutorial. Depending on the Labs you want to take, you only need to install a subset of the 5 tools described below.

Iar kickstart

This is required for all labs.

IAR is the tool used to program the eZ430-RF2500 boards. The free Kickstart version is limited to compiling 4kB of code.

Ti sensor monitor demo

This is required for all labs because it installs the drivers enabling your computer to talk to the mote.

Sensor Monitor is demo software which provides a graphical interface to the Texas Instruments Sensor Monitor Demo.

  • Download from (External Link) .
  • Follow default installation for Demo Visualizer, Sensor Monitor Installer.exe
  • Store the eZ430-RF2500 Wireless Sensor Monitor IAR Source v1.02 directory on your computer.

Putty

This is required for all labs.

PuTTY is used to read from the serial COM port created by the eZ430-RF2500 board when connected to the host computer.

  • Create folder C:/Program Files/putty/
  • Download (External Link) into that folder.

Xming

This is only used in Lab 5 .

Xming is a Linux-like X server which enables cygwin script to display windows.

  • Download from (External Link) .
  • Follow default install, but choose not to install any SSH client.

Cygwin

This is only used in Lab 5 .

Cygwin is a Linux-in-Windows environment, enabling Linux-like script execu- tion on a Windows machine.

  • Install from (External Link) .
  • Follow default installation. When asked for a Download Site, choose http://www.gtlib.gatech.edu This is a must as GATech's download site contains the python-numpy package we will need. .
  • When packages are listed, click on the button in the upper right corner until obtaining Full. You obtain a list of all installable packages (much like programs in Windows), marked with the word Skip when not installed, or the version number when installed.
  • Using that list, add the following packages. This is done by clicking on the work Skip next to the package name.
    • python : An interactive object-oriented scripting language
    • python-numpy : Python scientific computing module
    • gcc-g++ : C++ compiler
    • gnuplot : A command-line driven interactive function plotting utility
  • Click next several times to finish the installation.

The Python gnuplot extension enables us to visualize data output by the mote connected to the computer. To install it:

  • Open cygwin
  • download gnuplot-py-1.8.zip
  • unzip that file and place folder gnuplot-py-1.8/ within inside folder C:/cygwin/
  • open cygwin
  • type the following lines
    • cd /cygdrive/c/cygwin/
    • python setup.py install
  • open C:/cygwin/lib/python2.5/site-packages/Gnuplot/gp_cygwin.py with WordPad
  • change line default term = 'windows' to default term = 'x11'
  • change line gnuplot command = 'pgnuplot.exe' to gnuplot command = 'gnuplot.exe'

Start menu shortcuts

While not strictly necessary, creating Start Menu shortcuts will make your life easier.
  • Create a folder ezwsn in the Start Menu folder (typically C:/Documents and Settings/All Users/Start Menu/ )
  • in that folder, create shortcuts to the following programs:
    • PuTTY
    • IAR Embedded Workbench
    • XLaunch (part of Xming)
    • cygwin
    • eZ430-RF2500 Sensor Monitor

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone
definitely of physics

how do lnternal energy measures
Esrael
Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
