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

.. _fade-led-sample: PWM: Fade LED ############# Overview ******** This is a sample app which fades a LED using PWM. The LED will start from dark and increases its brightness gradually for 10 seconds. Then, the brightness reduces gradually for 10 seconds and finally the LED becomes dark again. The LED will repeat this cycle for ever. Wiring ****** Arduino 101 and Quark D2000 CRB =============================== You will need to connect the LED to ground and PWM0 via the shield. You may need a current limiting resistor. See your LED datasheet. Nucleo_F401RE and Nucleo_L476RG =============================== Connect PWM2(PA0) to LED Nucleo_F103RB ============= Connect PWM1(PA8) to LED Hexiwear K64 ============ No special board setup is necessary because there is an on-board RGB LED connected to the K64 PWM. Building and Running ******************** This sample can be built for multiple boards, in this example we will build it for the arduino_101 board: .. zephyr-app-commands:: :zephyr-app: samples/basic/fade_led :board: arduino_101 :goals: build flash :compact:
