Example Summary

Sample application to read temperature value from a TMP006 I2C temperature sensor.

Peripherals Exercised

• Board_LED0 - Indicator LED
• Board_I2C_TMP - I2C used to communicate with TMP006 sensor.

Resources & Jumper Settings

Please refer to the development board’s specific Settings and Resources section in the Getting Started Guide. For convenience, a short summary is also shown below.

Fields left blank have no specific settings for this example.

Example Usage

• Connect the TMP006 Booster Pack, if required, before powering the hardware.

• Run the example. Board_LED0 turns ON to indicate TI-RTOS driver initialization is complete.

• The example will request temperature samples from the TMP006 and print them on the console. A total of 20 temperature samples are read/printed before the example exits. Console output should resemble:

      I2C Initialized!
      Sample 0: 24 (C)
      Sample 1: 24 (C)
      Sample 2: 24 (C)
      Sample 3: 24 (C)

Application Design Details

This application uses one tasks:

'getTempTask' - performs the following actions:

1. Opens and initializes an I2C driver object.

2. Uses the I2C driver to get data from the TMP006 sensor.

3. Extracts the temperature (in Celsius) and prints the value on the console.

4. The task sleeps for 1000 system ticks.

5. After 20 temperature samples are recovered, the I2C peripheral is closed and the example exits.
