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> |

.. _mpr-sample: MPR Pressure Sensor ################### Overview ******** This sample application periodically (1Hz) measures atmospheric pressure in kilopascal. The result is written to the console. References ********** - MPR: https://sensing.honeywell.com/micropressure-mpr-series Wiring ****** This sample uses an MPRLS0025PA00001A sensor controlled using the i2c interface. Connect **VIN**, **GND** and Interface: **SDA**, **SCL**. Building and Running ******************** This project outputs sensor data to the console. It requires a sensor from the MPR series. It does not work on QEMU. In the sample below the :ref:`arduino_due` board is used. .. zephyr-app-commands:: :zephyr-app: samples/sensor/mpr :board: arduino_due :goals: build flash Sample Output ************* .. code-block:: console pressure value: 101.976303 kPa pressure value: 101.986024 kPa pressure value: 101.989736 kPa pressure value: 101.987424 kPa pressure value: 101.992099 kPa pressure value: 101.989171 kPa pressure value: 101.984226 kPa <repeats endlessly>
