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. 4 430BOOST-TMP006 BoosterPack SLAU440 – June 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Obtaining Software Packages www.ti.com 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).

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 redownload 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. 6 430BOOST-TMP006 BoosterPack SLAU440 – June 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated User Experience Application www.ti.com Change the conversion rate on how often to sample the target temperature Triggers a data dump from LaunchPad's memory buffer to the PC.
