* 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
For historical reasons (NuttX STM32 numbering) PX4 bus numbering is
1 based. All PX4 code, including, board code is written to assuming 1
based numbering. In the PX4 I2C driver the 1 is subtracted from the
buss number to address the freqency array. These macros are used to
allow the board config to define the bus numbers in terms of the NuttX
driver numbering. 1,2,3 for one based numbering (STM32) or 0,1,2
for zero based (Kinetis)
This will initialize those structs with zero in all fields not set
and all fields set will only be change once to the final value not
wasting CPU time zeroing it.
This will guarantee that no non-unitialized structs will have
a trash value on from_external causing it to be sent to the
MAVLink channel without need it.
Define the default I2C buss frequncies that are backward compatible
with the existing code. While allowing it the defaults to be overridden
by a board config.
Based on the legacy STM32 code, the I2C buss numbering starts at 1.
The bus frequency is stored in a 0 based array. If px4_i2cbus_initialize
returns a valid device, then the _bus-1 will act as the index to the
busses frequency.
A board may define BOARD_NUMBER_I2C_BUSES - the number of I2C busses
it supports* and BOARD_I2C_BUS_CLOCK_INIT to initalize the bus
clocks for a given busses.
BOARD_NUMBER_I2C_BUSES - the number of busses including the *highest
number bus. If the board has 2 I2C
busses I2C1 and I2C3 BOARD_NUMBER_I2C_BUSES
would be set to 3
BOARD_I2C_BUS_CLOCK_INIT - Initalization for the bus frequencies
by bus. A call init, with a frequency
less then the value used for the
Initalization will result in the device
not starting becuase the buss runs too
fast for it.
PX4_NUMBER_I2C_BUSES number of busses that the HW can support
not all of them my be usesd. I.E. The STM32F427 has 3 I2C
busses but only I2C1 and I2C3 are used.
The GPS simulation now mimicks the real driver more closely and should provide even GPS delays. The delays themselves are set by the simulator, and default to 120 ms for Gazebo
The simulation engine had the ability to pause already and properly handled load spikes, however, it was not hardened against constant drift. This addition enables it to run at a constant slower-than-realtime rate successfully.
