Minlure is a port of ArduPilot to Minnow Board connected to daughter
board. Very few of those were produced and nobody is flying with it.
It served its purpose and all the the improvements to ArduPilot remain
regardless of it not being supported anymore. Now it's just adding
maintenance work with no clear benefit, so pull the plug.
Navio2 exports its leds via /sys/class/leds interface. We reuse it in
order not to conflict with GPIO_Sysfs. Otherwise we'd get a Device Busy
error in GPIO_Sysfs::_export_pin().
Jaime did the hard work on this one. He reworked notify device
selection to take place on init rather than on compile like before. The
notify decivces are mostly set on compile using preprocessor directives
based on board type. I created NTF_OREO_THEME. This will allow the
user to enable/disable the OreoLED driver. And it also allows you to
select between aircraft and rover lighting themes. This allows the Solo
to use the OreoLEDs, and doesn't waste the memory on vehicles not
equipped with Oreo LEDs. The OreoLED driver is restricted to Pixhawk 2
FCs by proprocessor directive due to memory constraints. So it will
never work by accident on another board.
There is also a new notify flag for GPS Fusion. This flag is true when
the EKF is happy with the GPS, actively using it for position
information.
This makes the display architecture closer to our other frontend/backend splits
Added check that display is initialised successfully in hw_init
Renamed _update_timer to just _timer to make more consistent with other drivers
when this is set the board RGB LED will be controlled by MAVLink
instead of internally. This is useful for cases where the LED patterns
and colours needed are specified by an external authority (such as the
OBC organisers)
On early versions of minlure an RGB LED was wrongly placed next to the
barometer, causing trouble on it.
Additionally depending on the LED intensity it may be a pain to leave it
turned on for boards supposed to be used for bench testing. This allows
to disable the LED by software so we don't have to remove it.
