``nxlines`` NX Line Drawing
|
||
===========================
|
||
|
||
A very simple graphics example that just exercised the NX line drawing logic.
|
||
|
||
The following configuration options can be selected:
|
||
|
||
- ``CONFIG_EXAMPLES_NXLINES_VPLANE`` – The plane to select from the frame- buffer
|
||
driver for use in the test. Default: ``0``.
|
||
- ``CONFIG_EXAMPLES_NXLINES_DEVNO`` – The LCD device to select from the LCD driver
|
||
for use in the test: Default: ``0``.
|
||
- ``CONFIG_EXAMPLES_NXLINES_BGCOLOR`` – The color of the background. Default
|
||
depends on ``CONFIG_EXAMPLES_NXLINES_BPP``.
|
||
- ``CONFIG_EXAMPLES_NXLINES_LINEWIDTH`` – Selects the width of the lines in pixels
|
||
(default: ``16``).
|
||
- ``CONFIG_EXAMPLES_NXLINES_LINECOLOR`` – The color of the central lines drawn in
|
||
the background window. Default depends on ``CONFIG_EXAMPLES_NXLINES_BPP`` (there
|
||
really is no meaningful default).
|
||
- ``CONFIG_EXAMPLES_NXLINES_BORDERWIDTH`` – The width of the circular border drawn
|
||
in the background window. (default: ``16``).
|
||
- ``CONFIG_EXAMPLES_NXLINES_BORDERCOLOR`` – The color of the circular border drawn
|
||
in the background window. Default depends on ``CONFIG_EXAMPLES_NXLINES_BPP``
|
||
(there really is no meaningful default).
|
||
- ``CONFIG_EXAMPLES_NXLINES_CIRCLECOLOR`` – The color of the circular region
|
||
filled in the background window. Default depends on
|
||
``CONFIG_EXAMPLES_NXLINES_BPP`` (there really is no meaningful default).
|
||
- ``CONFIG_EXAMPLES_NXLINES_BORDERCOLOR`` – The color of the lines drawn in the
|
||
background window. Default depends on ``CONFIG_EXAMPLES_NXLINES_BPP`` (there
|
||
really is no meaningful default).
|
||
- ``CONFIG_EXAMPLES_NXLINES_BPP`` – Pixels per pixel to use. Valid options include
|
||
``2``, ``4``, ``8``, ``16``, ``24``, and ``32``. Default is ``16``.
|
||
- ``CONFIG_NSH_BUILTIN_APPS`` – Build the NX lines examples as an NSH built-in
|
||
function.
