TI_TMP116 Sample
################
Description
***********
This sample application periodically takes temperature readings using the ti_tmp116
sensor driver. The result is written to the console. This sample also included the code
to use the features provided by TMP117, which is a sensor similar to TMP116
Requirements
************
This sample needs a TI TMP116 or TI TMP117 sensor connected to the target board's I2C
connector.
Wiring
******
This sample is tested with Nucleo STM32F401RE board.
The sensor operates at 3.3V and uses I2C to communicate with the board.
External Wires:
* Breakout **GND** pin <--> Nucleo **GND** pin
* Breakout **VCC** pin <--> Nucleo **3V3** pin
* Breakout **SDA** pin <--> Nucleo **CN5-D14** pin
* Breakout **SCL** pin <--> Nucleo **CN5-D15** pin
Building and Running
********************
In order to build the sample, connect the board to the computer with a USB cable and enter the
following commands:
.. zephyr-app-commands::
:zephyr-app: samples/sensor/tmp116
:board: nucleo_f401re
:goals: build flash
:compact:
Sample Output
*************
The output can be seen via a terminal emulator (e.g. minicom). Connect the board with a USB cable
to the computer and open /dev/ttyACM0 with the below serial settings:
* Baudrate: 115200
* Parity: None
* Data: 8
* Stop bits: 1
The output should look like this:
.. code-block:: console
Device TMP116 - 0x200010a8 is ready
temp is 26.7031250 oC
temp is 26.7109375 oC
