If parameter INS_GYRO_CAL is disabled, usually because operator is
arming on a moving vehicle such as a boat, the Oreo LEDs would wait
indefinitely for a gyro calibration that will never happen. This
removes that dependency. The LEDs will strobe blue only when gyros are
actually initializing. Not before. Consequently, this greatly
simiplifies that portion of the code.
The UART3 also have the I2C bus 2 functions so moving GPS to UART7 to
have one additional I2C.
To keep GPS working is also necessary update the FPGA RTL to version
0xC1 or higher.
Unsure what the underlying problem is, but the length of the first string in
the initilisation_blob increasing resulted in a race condition, waiting
longer before retrying the message resolves it, but we still need to identify
the underlying problem. This patch just results in the GPS working with current
configurations. Tested against AsteRx-M firmware 3.6.3
Reworked the process flow. Created the aviation vs rover themes.
Created visual operator feedback for prearm checks, GPS, EKF, gyro init,
radio failsafe, and low battery. This also includes work by Hugh Eaves
to open up the full extended properties of the Oreo LEDs. Not only are
far more functions available, but you can override and do custom things
via mavlink.
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.
