430BOOST-TMP006 BoosterPack

1 430BOOST-TMP006 BoosterPack Overview

1.1 Overview

The 430BOOST-TMP006 BoosterPack provides a quick and low-cost solution to evaluate and develop

with the TMP006 contactless temperature sensor. To quickly get started, this BoosterPack comes with a

pre-loaded firmware for MSP430G2553 device. The software ecosystem also provides fully commented

source code for customers to get started with developing their application.. A GUI is also available for

interaction with the BoosterPack. See Figure 1 for an overview of the BoosterPack hardware.

TMP006 Information

www.ti.com

2 TMP006 Information

The TMP006 is a contactless temperature sensor that uses an infrared thermopile sensor to detect the

temperature of a target object. The TMP006 data sheet contains all relevant electrical information (both

analog and digital) pertaining to the device. The TMP006 User’s Guide answers many common questions

related to the operation of the TMP006, including critical application criteria, printed circuit board (PCB)

layout guidelines, and the equations used to calculate target object temperature.

2.1 TMP006EVM

This BoosterPack is intended to demonstrate how an MSP430 and TMP006 can integrate into one

system. To simplify this integration, the TMP006EVM is included as part of this BoosterPack kit. The

TMP006EVM hardware is well documented in the TMP006EVM User Guide; however, note that this

BoosterPack contains different software.

3 Getting Started

3.1 Requirements

TMP006 BoosterPack requires LaunchPad rev1.4 and above. See www.ti.com/launchpadwiki for more

information. TMP006 BoosterPack also requires a MSP430G2553 device, which is included. This device is

pre-programmed with the user experience firmware (see Section 5).

3.2 Configuring LaunchPad

1. LaunchPad rev1.4 and below requires cross jumpering the UART lines. See MSP-EXP430G2

LaunchPad Experimenter Board User's Guide (SLAU318) for more information.

2. For LaunchPad rev1.5, switch to hardware UART through J3 jumpers (see Figure 2).

Figure 2. J3 Jumper

3. Remove P1.6 jumper for I2C operation (see Figure 3).

Figure 3. P1.6 Jumper

4. Do not touch the TMP006 sensor.

5. Replace the existing LaunchPad device with the MSP430G2553 device inside the TMP006

BoosterPack. This device has been pre-loaded with the user experience firmware.

6. Insert BoosterPack on top of the LaunchPad.

Obtaining Software Packages

3.3 Connecting Hardware

Install the LaunchPad drivers included in the firmware package, if needed (see Section 4 for details on

downloading the latest software).

Connect LaunchPad using a USB cable to a PC that is running Windows (see Figure 4). If prompted,

allow Windows to install the software automatically.

Figure 4. Connect USB

4 Obtaining Software Packages

Download the latest software packages from www.ti.com/tmp006boosterpack.

Download the two software packages. One package contains the source code and binaries for

MSP430G2553 firmware. The other is the GUI application created in LabView for interacting with the

BoosterPack.

4.1 Re-Downloading or Modifying Firmware

This step is optional to get started if you have used the pre-loaded MSP430G2553 device inside the

TMP006 BoosterPack. This step can be used to reload the firmware with a newer version or to a blank

device. The quickest way to re-download firmware image is to run MSP430Flasher.bat inside the

bin/firmware folder.

To modify the firmware, see Section 5 regarding supported compilers.

4.2 Installing BoosterPack GUI

Extract the software zip software package with the filename 430boost_tmp006_gui_x_xx_xx_xx.zip.

Execute the setup.exe inside gui_installer folder and follow the installation instructions.

4.3 Starting The Demo Application

1. Determine LaunchPad COM port through the Windows Device Manager.

2. Launch TMP006 BoosterPack GUI software.

3. Select COM Port and OK (see Figure 5).

Figure 5. Select COM port and Click OK

5 User Experience Application

This software package includes the project files to allow customers re-compile the code for user

development. You could download free and unrestricted compilers and debuggers, including:

• Code Composer Studio™ version 5.2 (CCS)

• IAR Embedded Workbench™ v5.40.3

These project files are located inside 430boost_tmp006_x_xx_xx_xx.zip src folder with their respective

compiler names as the folder.

This application uses hardware UART using the MSP430G2553 USCI module to communicate to the PC

via the LaunchPad’s backchannel UART. The software is capable of using timer-based UART, but the

user would need to change the HARDWARE_UART definition inside the uart.h file, re-compile, and re-

download the firmware.

There are two main user application modes in this user experience code. It operates together with the GUI

application.

• Data Sampling Mode

• Data Logging Mode

5.1 Data Sampling Mode

This mode samples the object temperature and streams the data back to the PC via the MSP430

LaunchPad backchannel UART. The PC then displays the data on the GUI. The Object Temperature is

the calculated temperature of the object. The Local Temperature is the temperature with transient

correction filter applied.

When this mode is operating, the LED1 (RED) on the LaunchPad is on.

The BoosterPack has green (D1) and red (D2) LEDs onboard. These LEDs light up depending on how

cold or hot since it was last calibrated. The colder the temperature is from the calibrated value, the

brighter the green LED would be. The hotter the temperature is from the calibrated value, the brighter the

red led would be. To calibrate a new value, press the S1 button on the Launchpad.

5.2 Data Logging Mode

In this mode, temperature can be sampled without connection to a PC. An external power source like a

battery pack, not included, must be used. To start data logging mode, press the S2 button. This button is

required if the BoosterPack is used in an untethered mode from the PC. Ensure that LED1 is no longer

ON, which indicates that the firmware is no longer in Data Logging Mode.

To operate the following user configurations, the BoosterPack must be connected to a PC. Select the data

logging mode in the GUI or press the S2 button to switch the mode if the BoosterPack is in data sampling

mode. Clear the data logging buffer in flash memory by pressing Erase Flash Data on the GUI. To send

the data to the PC for data analysis, click Dump Flash Data to PC in the GUI. All of the logged

temperature from the flash memory is read. This data can then be used for data analysis; for example,

using an Excel® spreadsheet.
