5. 5 Installation Required! [1/5] Step 0: Requirements A laptop running Windows (XP preferred) An eZ430-RF2500 kit

6. 6 Installation Required! [2/5] Step 1: eZ430-RF2500 Sensor Monitor Demo While we will never run the Sensor Monitor (a graphical interface to the Texas Instruments Sensor Monitor Demo), installing this is the quickest way of installing the driver for Windows to understand the eZ430-RF2500 connected to your computer. run 'step 1/Sensor Monitor Installer.exe' or download it from the Internet http://www-s.ti.com/sc/techlit/slaa378.zip.http://www-s.ti.com/sc/techlit/slaa378.zip Use default configurations during installation Do not keep the Sensor Monitor program running after the install, as it will interfere with the other tools we will be using

7. 7 Installation Required! [3/5] Step 2: IAR Kickstart for MSP430 IAR is the tool used to program the eZ430-RF2500 boards. Kickstart is the free edition, which can compile binary code up to 4kB in size. For larger sizes (not used in this tutorial), you need to buy the full version of IAR. Download the latest IAR Embedded Workbench kickstart edition for MSP430 from http://www.iar.com/ (currently version 5.10, 103MB) Use the default configuration settings during installation

8. 8 Installation Required! [4/5] Step 3: PuTTY PuTTY is used to read from the serial COM port created when the eZ430-RF2500 board is connected to the host computer. Download http://the.earth.li/sgtatham/putty/latest/x86/putty.exe (currently release 0.60, 444kB) There is no installation needed, double-clicking should start the application

9. 9 Installation Required! [5/5] Step 4: Python and PySerial We will use Python scripts to interface our laptops with the eZ430- RF2500. Download and install Python from http://www.python.org/, versions 2.5.4 and 2.6.4 are known to work Download and install PySerial (which allows Python to connect to a serial, or COM, port) from http://pyserial.sourceforge.net/, pyserial-2.5-rc1.win32.exe is known to work
