If all devices are communicating correctly, the user should be able to see temperature change over time in the TMP102 Temperature box. Figure 12. TMP102 Reading from Registers 12 TMP102EVM Evaluation Board and Software Tutorial Copyright © 2011, Texas Instruments Incorporated SBOU114 – August 2011 Submit Documentation Feedback TMP102EVM Software Overview www.ti.com 5.2.2 Writing to Registers The TMP102EVM software contains two different methods for writing data: Write All Reg and Auto-Write Reg. Writing the registers individually without Auto-write can be useful when adjusting large numbers of the configuration registers on the left side of the panel. The Auto-write feature automatically makes changes to the configuration register whenever one of the configuration settings on the left changes, as shown in Figure 13. Figure 13. TMP102 Writing to Registers SBOU114 – August 2011 Submit Documentation Feedback TMP102EVM Evaluation Board and Software Tutorial Copyright © 2011, Texas Instruments Incorporated 13 TMP102EVM Software Overview 5.2.3 www.ti.com Reading the Temperature Gauge The Temperature box on the TMP102EVM software window displays the measured values of the TMP102 registers in a graphical format, as Figure 14 shows. This value can be toggled to either (degrees) Fahrenheit or Celsius by toggling the checkbox at the bottom of the window. It is important to note that changing to extended mode on the TMP102EVM software also changes the full-scale value of TMP102 thermometer. Figure 14. Reading the Temperature Gauge 5.2.4 Polarity (Alert Pin) The polarity drop-down selection box in the Configuration section allows the user to toggle how the Alert pin behaves when it is triggered. When the polarity box is set to Active Low, as shown in Figure 15, the LED on the TMP102EVM board lights up when triggered and acts as a ground source. When the polarity box is set to Active High, the LED on the TMP102EVM board does not function, and the Alert pin on the TMP102 is set to DVDD when triggered. Figure 15. Configuring the Polarity 14 TMP102EVM Evaluation Board and Software Tutorial Copyright © 2011, Texas Instruments Incorporated SBOU114 – August 2011 Submit Documentation Feedback TMP102EVM Software Overview www.ti.com 5.2.5 Shutdown Mode The TMP102 has a built-in shutdown mode that allows the device to stop consuming power. The Shutdown mode selection box (illustrated in Figure 16) can also be used to clear the Alert pin when the Interrupt Mode (refer to Section 5.2.7) is selected. It is important to note that the TMP102 EVM cannot perform temperature conversions while in Shutdown mode. Figure 16. Active and Shutdown Mode 5.2.6 Extended Mode The TMP102EVM has two modes for storing converted temperature data as shown in Figure 17: Extended Mode and Normal Mode. Normal mode gives the Temperature, TLOW, and THIGH Registers 12 bits of accuracy. By changing to Extended Mode, the user increases to 13 bits of accuracy and adjusts the full-scale value of the three registers from 120°C to 150°C. It is important to note that adding an additional bit of accuracy also changes the current THIGH and TLOW values; these values must then be reset to the user's original, intended values after adjusting the Extended Mode drop-down box. Figure 17. Extended Mode and Normal Mode 5.2.7 Thermostat Mode Thermostat Mode, in the Configuration box, allows the user to designate how the TMP102 Alert pin behaves when the Temperature Register exceeds the THIGH Register. When the TMP102EVM software is in Comparator Mode, the Alert pin triggers if the temperature measured by the TMP102 exceeds the THIGH Register for the set amount of faults, described in the Fault Queue (see Section 5.2.9). Once the Alert pin has been triggered, it remains triggered until the temperature measured by the TMP102 falls below the TLOW Register value for the set amount of faults. SBOU114 – August 2011 Submit Documentation Feedback TMP102EVM Evaluation Board and Software Tutorial Copyright © 2011, Texas Instruments Incorporated 15 TMP102EVM Software Overview www.ti.com When the TMP102EVM software is in Interrupt Mode, the Alert pin does not automatically clear after it falls below the TLOW Register limit. Instead, the user must either select the Read All Reg button or put the device into Shutdown mode, described in Section 5.2.5. After the Read All Reg button is selected, or the device is put into Shutdown Mode, the Alert pin clears when the measured temperature drops down below the TLOW Register. Figure 18 illustrates the Thermostat Mode dialog. Figure 18. Comparator/Interrupt Mode 5.2.8 Conversion Rate The Conversion Rate selection box (shown in Figure 19) allows the user to change how long each temperature conversion takes the TMP102 to perform. The user may want to select a slower conversion time, as shown in Figure 19, to make the TMP102 consume less power. Figure 19. Conversion Rate 5.2.9 Fault Queue The fault queue drop-down box allows the user to configure how many faults must be triggered before the Alert pin is activated, as shown in Figure 20. A fault is generated whenever the TMP102 THIGH Register is exceeded by the Temperature Register. This feature can be useful to prevent the TMP102 from triggering on temperature spikes that the user may not want to trigger with the Alert pin. Figure 20. Setting the Fault Queue 16 TMP102EVM Evaluation Board and Software Tutorial Copyright © 2011, Texas Instruments Incorporated SBOU114 – August 2011 Submit Documentation Feedback TMP102EVM Software Overview www.ti.com 5.2.10 Alert Configuration (TLOW and THIGH) The Alert Config box has three objects that make up the main functionality of the TMP102 Alert pin, as Figure 21 shows: the Alert bit, TLOW Register, and THIGH Register. The green LED within the Alert Config box lights up when the THIGH Register has been exceeded and the Alert pin has been activated. It is denoted as a Alert because of the default configuration. The Alert pin can also be switched to an active high, as shown in Section 5.2.4, if so desired by the user. Figure 21. Alert Config Box The TLOW input box allows the user to set when the alert pin is cleared. When the measured value in the temperature register falls below the TLOW threshold, the Alert pin clears, depending on which thermostat mode is selected. For more information on the behavior of the Thermostat mode, see Section 5.2.7. The THIGH input box allows the user to set when the Alert pin is triggered. When the measured value in the temperature register exceeds the THIGH threshold, the Alert pin triggers until the temperature returns to a value below the TLOW threshold, depending on the thermostat mode selected. 5.2.11 Registers Tab The registers tab displays the individual register setting for the TMP102 sensors. For more information on the individual registers and the bit meanings, simply highlight the desired register and hit the Help with Reg button shown in Figure 22. Figure 22. Register Tab The Registers tab also includes the Dig_Bits table. The Dig_Bits table allows the user to monitor and change individual bits by highlighting the desired register and toggling the bit controls beneath it. NOTE: Only the bits that can be written within a given register can be toggled.
