As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

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
