TI_TMP11X Sample
################
Description
***********
This sample application periodically takes temperature readings using the ti_tmp11x
sensor driver. The result is written to the console. This sample also included the code
to use the features provided by TMP117 and TMP119, which are sensors similar to TMP116.
Requirements
************
This sample needs a TI TMP116, TI TMP117 or TI TMP119 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/tmp11x
: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 TMP11X - 0x200010a8 is ready
temp is 26.7031250 oC
temp is 26.7109375 oC
