What is QNX?
|
||||
------------
|
||||
|
||||
QNX is a commercial operating system first released in 1980. The operating
|
||||
system is based on a micro-kernel design, with the file system(s), network
|
||||
stack, and various other drivers each running in its own process with a separate
|
||||
address space.
|
||||
|
||||
See www.qnx.com for more details.
|
||||
|
||||
Highlight of QNX
|
||||
~~~~~~~~~~~~~~~~
|
||||
|
||||
- 64-bit only, runs on x86_64 and ARMv8
|
||||
- Requires an MMU as the design mandates separation among processes
|
||||
- Support for thousands of processes and millions of threads
|
||||
- Up to 64 cores, up to 16TB of RAM
|
||||
- Virtualization support (as host and guest)
|
||||
- Full POSIX compatibility
|
||||
- Safety certification to various automotive, industrial and medical standards
|
||||

||||
How to run LVGL on QNX?
|
||||
-----------------------
|
||||
|
||||
Build LVGL
|
||||
~~~~~~~~~~
|
||||
|
||||
The top-level `qnx` directory includes a recursive make file for building LVGL,
|
||||
both as a shared library and as a static library for the supported
|
||||
architectures. To build all libraries, simply invoke `make` in this directory:
|
||||
|
||||
.. code:: shell
|
||||
|
||||
# cd $(LVGL_ROOT)/qnx
|
||||
# make
|
||||
|
||||
If you prefer to build for a specific architecture and variant, go to the
|
||||
appropriate directory and run `make` there. For example, to build a shared
|
||||
library for ARMv8:
|
||||
|
||||
.. code:: shell
|
||||
|
||||
# cd $(LVGL_ROOT)/qnx/aarch64/so.le
|
||||
# make
|
||||
|
||||
As a general rule, if you only want to have one LVGL application in your system
|
||||
then it is better to use a static library. If you have more than one, and
|
||||
especially if they run concurrently, it is better to use the shared library.
|
||||
|
||||
Before building the library, you may wish to edit `$(LVGL_ROOT)/qnx/lv_conf.h`,
|
||||
e.g. to enable double-buffering.
|
||||
|
||||
Writing a LVGL Application
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
To create a LVGL application for QNX, follow these steps in your code:
|
||||
|
||||
1. Initialize the library.
|
||||
2. Create a window.
|
||||
3. Add the input devices.
|
||||
4. Create the UI.
|
||||
5. Run the event loop.
|
||||
|
||||
Steps 2, 3 and 5 use QNX-specific calls, but the rest of the code should be
|
||||
identical to that of a LVGL application written for any other platform.
|
||||
|
||||
The following code shows how to create a "Hello World" application:
|
||||
|
||||
.. code:: c
|
||||
|
||||
#include <lvgl.h>
|
||||
|
||||
int
|
||||
main(int argc, char **argv)
|
||||
{
|
||||
/* Initialize the library. */
|
||||
lv_init();
|
||||
|
||||
/* Create a 800x480 window. */
|
||||
lv_display_t *disp = lv_qnx_window_create(800, 480);
|
||||
lv_qnx_window_set_title(disp, "LVGL Example");
|
||||
|
||||
/* Add a keyboard and mouse devices. */
|
||||
lv_qnx_add_keyboard_device(disp);
|
||||
lv_qnx_add_pointer_device(disp);
|
||||
|
||||
/* Generate the UI. */
|
||||
lv_obj_set_style_bg_color(lv_screen_active(), lv_color_hex(0x003a57), LV_PART_MAIN);
|
||||
|
||||
lv_obj_t * label = lv_label_create(lv_screen_active());
|
||||
lv_label_set_text(label, "Hello world");
|
||||
lv_obj_set_style_text_color(lv_screen_active(), lv_color_hex(0xffffff), LV_PART_MAIN);
|
||||
lv_obj_align(label, LV_ALIGN_CENTER, 0, 0);
|
||||
|
||||
/* Run the event loop until it exits. */
|
||||
return lv_qnx_event_loop(disp);
|
||||
}
|
||||
|
||||
Build the Application
|
||||
~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Building the application consists of compiling the source with the LVGL headers,
|
||||
and then linking against the library. This can be done in many ways, using
|
||||
different build systems. The following is a simple make file for the example
|
||||
above, which builds for ARMv8 with the shared library:
|
||||
|
||||
.. code:: makefile
|
||||
|
||||

||||

|
||||
