The geometry was previously quad_deadcat in which front motors are closer to CG and thus more loaded in hover.
quad_wide is the same geometry as quad_deadcat except the CG is centered so all motors are loaded equally.
Flight logs on IRIS with deadcat mixer showed that
- all motors are equally loaded during hover (actuator_outputs 0 to 3 have similar values)
- a negative pitch offset is building up soon after takeoff (visible in actuator_controls)
- SYS_FMU_TASK is now enabled for PX4FMU_V4 PX4FMU_V4PRO PX4FMU_V5, but
it's only set on autoconf
- v5 companion is now TELEM2 (same as all other boards)
Adding a seperate cmake config to support RTPS messaging on AeroFC. This will
include compiling protocol_splitter and micrortps_client, and starting both
of them at boot time.
The config mode uses high rates for many streams, leading to high CPU usage
(9-10% for the mavlink sender). The normal mode contains almost the same
set of messages but at lower rates.
This reduces the CPU load on a Pixracer by 3-4%.
This commit is an attempt to fix a race condition happening on takeoff
between the land detector and the multicopter position controller.
Previously, an auto-takeoff leads to the following events:
1. A takeoff setpoint is given.
2. The thrust setpoint spikes because we don't enter smooth takeoff yet.
3. The land detector detects a takeoff because of the high thrust.
4. The position controller sees the landed state transition and
initiates the smooth takeoff. Thrust goes back down.
5. Depending on control gains the takeoff is successful or fails
if the smoothing takes too long which causes thrust to be too low, so
the land detector detects land again.
The two obvious problems with this are:
- The intermittent spike.
- The failed takeoff because of the smoothing leads to a delay..
With this change, the logic for a takeoff detection is moved from the
land detector to the position controller.
The events are now:
1. A takeoff setpoint is given.
2. The position controller detects the takeoff setpoint and initiates
the smooth takeoff.
3. As thrust ramps up, the land detector detects the take off.
In the same way, we now detect the intent to takeoff in manual,
altitude, control, position control in the position controller instead
of in the land detector.
* NuttX cmake
* px4_macros:Pass the stringified predicate as second arg to static assert
CC_ASSERT mapes to the c++ static_assert or provides the same
funtionality for c via the other macros. The c++ static assert
takes 2 argumants the prdicate and a message. This fixes the
lacking second argument.
* Updated nuttx and apps submodule to upstream nuttx 7.21+==master
This is the latest uptake of upstream nuttx and apps.
* ROMFS generate with xxd instead of objcopy
* delete nuttx-patches
* NuttX update submodules to latest px4_nuttx-master
* fix nuttx apps and board dependency
* docker_run update to latest container 2017-08-29
* cmake ROMFS portable sed usage
* NuttX update submodules to latest px4_nuttx-master
