The nRF52840 DK board target, so far known as nrf52840_pca10056, is renamed to nrf52840dk_nrf52840. Its documentation and all references to its name in the tree are updated accordingly. Overlay and configuration files specific to this board are also renamed, to match the new board name. Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>

Overview
|
|
********
|
|
|
|
This sample application displays "Hello World" in the center of the screen
|
|
and a counter at the bottom which increments every second. If an input driver
|
|
is supported, such as the touch panel controller on mimxrt10{50,60,64}_evk
|
|
boards, "Hello World" is enclosed in a button that changes to the toggled state
|
|
when touched.
|

|
Requirements
|
|
************
|
|
|
|
Display shield and a board which provides a configuration
|
|
for Arduino connectors, for example:
|
|
|
|
- :ref:`adafruit_2_8_tft_touch_v2` and :ref:`nrf52840dk_nrf52840`
|
|
- :ref:`ssd1306_128_shield` and :ref:`frdm_k64f`
|
|
|
|
or a simulated display environment in a native Posix application:
|
|
|
|
- :ref:`native_posix`
|
|
- `SDL2`_
|
|
|
|
or
|
|
|
|
- :ref:`mimxrt1050_evk`
|
|
- `RK043FN02H-CT`_
|
|
|
|
or
|
|
|
|
- :ref:`mimxrt1060_evk`
|
|
- `RK043FN02H-CT`_
