Example Summary

Application that registers temperature based notifications and toggles LEDs.

Peripherals & Pin Assignments

When this project is built, the SysConfig tool will generate the TI-Driver configurations into the ti_drivers_config.c and ti_drivers_config.h files. Information on pins and resources used is present in both generated files. Additionally, the System Configuration file (*.syscfg) present in the project may be opened with SysConfig’s graphical user interface to determine pins and resources used.

• CONFIG_GPIO_LED_0 - Toggled by Temperature driver notification
• CONFIG_GPIO_LED_1 - Turned on or off by Temperature driver notification

BoosterPacks, Board Resources & Jumper Settings

For board specific jumper settings, resources and BoosterPack modifications, refer to the Board.html file.

If you’re using an IDE such as Code Composer Studio (CCS) or IAR, please refer to Board.html in your project directory for resources used and board-specific jumper settings.

The Board.html can also be found in your SDK installation:

<SDK_INSTALL_DIR>/source/ti/boards/<BOARD>

Example Usage

• Open a serial session (e.g. PuTTY, etc.) to the appropriate COM port.
  • The COM port can be determined via Device Manager in Windows or via ls /dev/tty* in Linux.

The connection will have the following settings:

    Baud-rate:     115200
    Data bits:          8
    Stop bits:          1
    Parity:          None
    Flow Control:    None

• Run the example.

• CONFIG_GPIO_LED_0 is toggled when the temperature of the chip changes more than THRESHOLD_DELTA degrees C.

• CONFIG_GPIO_LED_1 is turned on when the temperature is above THRESHOLD_CUTOFF degrees C and turned off when the temperature falls below this threshold.

• The current temperature in degrees C is printed to the console once per second.
