This is the FGPanel for the Raspberry Pi running Raspbian.
|
|
|
|
|
It should work with other Linux distributions but it has not been tested.

INSTALLATION
|
|
|
|
|
============
|
|
|
|
|
|
|
|
|
|
1. Build SimGear as usual.
|
|
|
|
|
OSG, Plib, GLUT,... will be required even they are not strictly needed to run FGPanel.
|
|
|
|
|
|
|
|
|
|
2. Configure FlightGear using CMake as usual.
|
|
|
|
|
CMakeLists.txt is used to compile FGPanel with OpenGL 2.0.
|
|
|
|
|
This should make FGPanel faster on modern graphics cards.
|
|
|
|
|
|
|
|
|
|
CMakeLists.txt is used to compile FGPanel with OpenGL ES 2.0 for the Raspberry Pi.
|
|
|
|
|
The source code of FGPanel can easily be adapted to other embedded devices supporting OpenGL ES 2.0.
|
|
|
|
|
|
|
|
|
|
3. Build FGPanel only (don't build all components on the Raspberry Pi as this will take ages!!!):
|

|
|
|
make -- fgpanel-egl fgpanel

USAGE (fgpanel-egl)
|
|
|
|
|
===================
|
2016-12-04 18:36:53 +00:00
|
|
|
|
|
|
|
|
1. Increase the amount of GPU memory by editing the /boot/config.txt file.
|
|
|
|
|
Add the following line (this is for Raspberry Pi model 1B with 512 Mb of memory):
|
|
|
|
|
gpu_mem_512=256
|
|
|
|
|
|
|
|
|
|
2. Reboot and check the amount of GPU memory:
|
|
|
|
|
vcgencmd get_mem gpu
|
|
|
|
|
|
|
|
|
|
3. Stop X server. FGPanel runs in the console (Linux framebuffer).
|
|
|
|
|
|
|
|
|
|
4. Start FGPanel as usual but as ROOT or use the 'sudo' command (see README):
|
2020-04-01 20:01:07 +00:00
|
|
|
sudo -- utils/fgpanel/fgpanel-egl --fg-root=/path/to/fg/data --panel=Aircraft/MyAircraft/Panels/MyPanel.xml
|

|
|
|
|
|
|
|
|
ROOT privileges are required to access the GPU of the Raspberry Pi.

USAGE (fgpanel)
|
|
|
|
|
===================
|
|
|
|
|
|
|
|
|
|
1. Activate the Full KMS driver on the Raspberry Pi using the raspi-config program:
|
|
|
|
|
Advanced Options -> GL Driver -> Full KMS
|
|
|
|
|
|
|
|
|
|
2. Reboot. The Full KMS driver should be activated.
|
|
|
|
|
|
|
|
|
|
3. When X server is running, start FGPanel as usual (see README):
|
|
|
|
|
utils/fgpanel/fgpanel --fg-root=/path/to/fg/data --panel=Aircraft/MyAircraft/Panels/MyPanel.xml

FEATURES
|
|
|
|
|
========
|
|
|
|
|
|
|
|
|
|
- Use OpenGL 2.0 instead of OpenGL 1.0 (fixed pipeline) using CMakeLists.txt.
|
|
|
|
|
- Use OpenGL ES 2.0 to run on the Raspberry Pi using CMakeLists.txt.
|
|
|
|
|
- Use VideoCore 4 graphics hardware acceleration (GPU) of the Raspberry Pi.
|
|
|
|
|
- Run at 30 frames per second.
|
|
|
|
|
- Don't use PLib anymore for the font rendering.
