6Description
7***********
8
9This sample application periodically takes temperature readings using the ti_tmp116
10sensor driver. The result is written to the console. This sample also included the code
11to use the features provided by TMP117, which is a sensor similar to TMP116
12
13Requirements
14************
15
16This sample needs a TI TMP116 or TI TMP117 sensor connected to the target board's I2C
17connector.

20Wiring
21******
22
23This sample is tested with Nucleo STM32F401RE board.
24
25The sensor operates at 3.3V and uses I2C to communicate with the board.

29* Breakout **GND** pin <--> Nucleo **GND** pin
30* Breakout **VCC** pin <--> Nucleo **3V3** pin
31* Breakout **SDA** pin <--> Nucleo **CN5-D14** pin
32* Breakout **SCL** pin <--> Nucleo **CN5-D15** pin

37In order to build the sample, connect the board to the computer with a USB cable and enter the
38following commands:

46Sample Output
47*************
48The output can be seen via a terminal emulator (e.g. minicom). Connect the board with a USB cable
49to the computer and open /dev/ttyACM0 with the below serial settings:
50
51* Baudrate: 115200
52* Parity: None
53* Data: 8
54* Stop bits: 1
55
56The output should look like this:
