Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com> |

.. _lsm303dlhc: LSM303DLHC: Magnetometer and Accelerometer data Monitor ####################################################### Overview ******** This sample application periodically reads magnetometer and accelerometer data from the LSM303DLHC eCompass module's sensors, and displays the sensor data on the console. Requirements ************ This sample uses the LSM303DLHC, ST MEMS system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor, controlled using the I2C interface. References ********** For more information about the LSM303DLHC eCompass module, see http://www.st.com/en/mems-and-sensors/lsm303dlhc.html Building and Running ******************** This project outputs sensor data to the console. It requires a LSM303DLHC system-in-package, which is present on the stm32f3_disco board .. zephyr-app-commands:: :zephyr-app: samples/sensor/lsm303dlhc :board: stm32f3_disco :goals: build :compact: Sample Output ============= .. code-block:: console Magnetometer data: ( x y z ) = ( 0.531818 -0.435454 -0.089090 ) Accelerometer data: ( x y z ) = ( -0.078127 -0.347666 1.105502 ) Magnetometer data: ( x y z ) = ( -0.003636 0.297272 -0.255454 ) Accelerometer data: ( x y z ) = ( 0.074221 -0.304696 0.972685 ) <repeats endlessly every 2 seconds>
