New page

== Gaming buttons ==

The pandora gaming buttons are mapped to certain keyboards keys. Here is the list :
{|class="wikitable sortable" border="1" cellpadding="1" cellspacing="0" style="font-size: 90%; border:1px solid gray; border-collapse: collapse; text-align: left;"
!Button
!SDLK key code
|-
|A
|SDLK_HOME
|-
|B
|SDLK_END
|-
|X
|SDLK_PAGEDOWN
|-
|Y
|SDLK_PAGEUP
|-
|START
|SDLK_LALT
|-
|SELECT
|SDLK_LCTRL
|-
|L
|SDLK_RSHIFT
|-
|R
|SDLK_RCTRL
|}

== Working with the nubs ==

The nubs can be used as mouse or as joystick and can be set independly one from the other. Here is the list of available mode :

{|class="wikitable sortable" border="1" cellpadding="1" cellspacing="0" style="font-size: 90%; border:1px solid gray; border-collapse: collapse; text-align: center;"
!Mode
!Description
|-
|mouse
|For mouse mouvements
|-
|mbuttons
|Mouse buttons
|-
|scroll
|like a 4d mouse wheel
|-
|absolute
|Joystick mode
|}

for more informations see the [[Nubs]].
=== Changing nub status in a start script ===
Here is the best way to set the nubs in joystick mode :

<source lang="bash">
export NUB0MODE=`cat /proc/pandora/nub0/mode`
export NUB1MODE=`cat /proc/pandora/nub1/mode`
if [ -e /usr/pandora/scripts/op_nubchange.sh ]; then
/usr/pandora/scripts/op_nubchange.sh absolute absolute
else
echo absolute > /proc/pandora/nub0/mode
echo absolute > /proc/pandora/nub1/mode
fi
# start your app here

# now revert them to the original state
if [ -e /usr/pandora/scripts/op_nubchange.sh ]; then
/usr/pandora/scripts/op_nubchange.sh $NUB0MODE $NUB1MODE
else
echo $NUB0MODE > /proc/pandora/nub0/mode
echo $NUB1MODE > /proc/pandora/nub1/mode
fi
</source>

=== Finding the nub using SDL ===

// Joystick vars
#ifdef PANDORA
static SDL_Joystick *vid_sdlnub1 = NULL;
static SDL_Joystick *vid_sdlnub2 = NULL;
#endif

// Initialisation code

else if (!strcmp(SDL_JoystickName(i), "nub1"))
vid_sdlnub2 = SDL_JoystickOpen(i);
}
#endif
