LittlevGL Basic Sample

######################

|
|
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:`nrf52840_pca10056`
|
|
- :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`_
|
|
