History

Keith Packard 0b90fd5adf samples, tests, boards: Switch main return type from void to int 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.

LSM6DSO: IMU Sensor Monitor
###########################

Overview
********
This sample sets the date rate of LSM6DSO accelerometer and gyroscope to
12.5Hz and enables a trigger on data ready. It displays on the console
the values for accelerometer and gyroscope.

Requirements
************

This sample uses the LSM6DSO sensor controlled using the I2C interface.
It has been tested on the :ref:`stm32l562e_dk_board`.

Building and Running
********************

 This project outputs sensor data to the console. It requires an LSM6DSO
 sensor, which is present on the :ref:`stm32l562e_dk_board`.
