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>
.. _bme680: BME680: Integrated environmental sensor ##################################################### Description *********** This sample application periodically (every 3s) measures the ambient temperature in degrees Celsius, atmospheric pressure in kilopascal, relative humidity in percentage, and gas sensor resistance in ohms. The result is written to the console. References ********** - BME680: https://www.bosch-sensortec.com/bst/products/all_products/bme680 Wiring ******* This sample uses the BME680 sensor controlled using the I2C interface. Connect Supply: **VDD**, **VDDIO**, **GND** and Interface: **SDA**, **SCL**. The supply voltage can be in the 1.8V to 3.6V range. Depending on the baseboard used, the **SDA** and **SCL** lines require Pull-Up resistors. Building and Running ******************** This project outputs sensor data to the console. It requires a BME680 sensor. It should work with any platform featuring a I2C peripheral interface. It does not work on QEMU. In this example below the :ref:`nrf52840dk_nrf52840` board is used. .. zephyr-app-commands:: :zephyr-app: samples/sensor/bme680 :board: nrf52840dk_nrf52840 :goals: build flash Sample Output ============= .. code-block:: console Device 0x20002b74 name is BME680 T: 23.988877; P: 97.648568; H: 53.689533; G: 1035.211466 T: 24.168500; P: 97.648866; H: 53.565966; G: 1046.677896 T: 24.336533; P: 97.648596; H: 53.353663; G: 1058.656533 T: 24.589696; P: 97.648366; H: 53.958864; G: 1072.155863 T: 24.856631; P: 97.648322; H: 53.553669; G: 1096.448788 <repeats endlessly>
