As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>. This patch proposes to then include <zephyr/kernel.h> instead of <zephyr/zephyr.h> since it is more clear that you are including the Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a catch-all header that may be confusing. Most applications need to include a bunch of other things to compile, e.g. driver headers or subsystem headers like BT, logging, etc. The idea of a catch-all header in Zephyr is probably not feasible anyway. Reason is that Zephyr is not a library, like it could be for example `libpython`. Zephyr provides many utilities nowadays: a kernel, drivers, subsystems, etc and things will likely grow. A catch-all header would be massive, difficult to keep up-to-date. It is also likely that an application will only build a small subset. Note that subsystem-level headers may use a catch-all approach to make things easier, though. NOTE: This patch is **NOT** removing the header, just removing its usage in-tree. I'd advocate for its deprecation (add a #warning on it), but I understand many people will have concerns. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no> |

.. _lp5562: LP5562: 4-Channel RGB ###################### Overview ******** This sample controls 4 LEDs connected to a TI LP5562 driver, using the following pattern: 1. turn on LEDs to be red 2. turn on LEDs to be green 3. turn on LEDs to be blue 4. turn on LEDs to be white 5. turn on LEDs to be yellow 6. turn on LEDs to be purple 7. turn on LEDs to be cyan 8. turn on LEDs to be orange 9. turn off LEDs 10. blink the LEDs in white 11. turn off LEDs 12. blink the LEDs in purple 13. turn off LEDs Refer to the `LP5562 Manual`_ for the RGB LED connections and color channel mappings used by this sample. Building and Running ******************** Build the application for the :ref:`nrf52840dk_nrf52840` board, and connect a LP5562 LED driver on the bus I2C0 at the address 0x30. .. zephyr-app-commands:: :zephyr-app: samples/drivers/led_lp5562 :board: nrf52840dk_nrf52840 :goals: build :compact: For flashing the application, refer to the Flashing section of the :ref:`nrf52840dk_nrf52840` board documentation. .. _LP5562 Manual: http://www.ti.com/lit/ds/symlink/lp5562.pdf
