These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

.. _adt7420: ADT7420: High accuracy digital I2C temperature sensor ##################################################### Description *********** This sample application periodically (1Hz) measures the ambient temperature in degrees Celsius. The result is written to the console. Optionally, it also shows how to use the upper and lower threshold triggers. References ********** - ADT7420: http://www.analog.com/adt7420 Wiring ******* This sample uses the ADT7420 sensor controlled using the I2C interface. Connect Supply: **VDD**, **GND** and Interface: **SDA**, **SCL** and optionally connect the **INT** to a interrupt capable GPIO. The supply voltage can be in the 2.7V to 5.5V 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 an ADT7420 sensor. It should work with any platform featuring a I2C peripheral interface. It does not work on QEMU. In this example below the :ref:`nrf52_pca10040` board is used. .. zephyr-app-commands:: :zephyr-app: samples/sensors/adt7420 :board: nrf52_pca10040 :goals: build flash Sample Output ============= .. code-block:: console device is 0x20002b74, name is ADT7420 temperature 24.984375 C temperature 24.968750 C temperature 24.968750 C temperature 24.968750 C temperature 24.953125 C <repeats endlessly>
