Due to higher bias, V open circuit on the ADC is high with a 1M
termination. This override the default connected threshold on
V5 HW. Revist once lowe termination is chosen.
* 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
was:<nuttx/arch.h> is:platform/cxxinitialize.h
Removed PX4 version:src/modules/systemlib/up_cxxinitialize.c
in favor of nuttx platform/gnu/gnu_cxxinitialize.c
Test HW has R and G LED swapped and drives the UI LED's active
high. The changes support all the configuratons of FMUv5 on
RC00 and RC01 HW for PWM status and UI LEDs.
Added palarity mask to support active low drive on per channel
bassis.
Added open drain drive type when the enables are active low to
ensure the LED are off when supplied form 5 volts.
For active Push Pull is used. Active low drive is recomended.
Added support for test HW that had the R and G LED signals
swapped.
Use the board supplied Power control macros, in the
the board_peripheral_reset.
This abstacts the polarity from the code. Therefore changes
in signal sense can be made, just in the board config.
RC00 had an active high VDD_5V_PERIPH_EN
PC01 has an active low VDD_5V_PERIPH_EN
RC00 Test hardware did not use an LTC4417
While RC00 HW is still in circulation you can build with
PX4_FMUV5_RC00 defined and BOARD_HAS_LTC4417 undefined.
The default is PX4_FMUV5_RC01 and BOARD_HAS_LTC4417 defined.
BOARD_HAS_LTC44XX_VALIDS - 0 -> No LTC44xx IC, N is the number of
Power Bricks connected to the LTC44xx
For a LTC4417 this would be 2 as the
third prioriy is used for USB
BOARD_HAS_USB_VALID - If defied as 1 imples that infact
the USB has a priority connection
on the LTC44XX
BOARD_HAS_NBAT_V - the number of battery voltage sensing chennels
on the ADC
BOARD_HAS_NBAT_I - the number of battery current sensing chennels
on the ADC
A super simple (non FMUv5 compliant) board with no LTC44xx and just one battery
that have no current sense:
BOARD_HAS_LTC44XX_VALIDS = 0
BOARD_HAS_USB_VALID = 0
BOARD_HAS_NBAT_V = 1
BOARD_HAS_NBAT_0 = 0
A fully FMUv5 compliant design would use:
BOARD_HAS_LTC44XX_VALIDS = 2
BOARD_HAS_USB_VALID = 1
BOARD_HAS_NBAT_V = 2
BOARD_HAS_NBAT_0 = 2
These setting properly condition the ADC channles and all the Power
module valid sensing logic in the ADC module.
The PX4IO is an population option on some varients. To have
1) FMU only control
2) IO Only control
3) FMU fall back control
These pins need to come up as inputs, until the configuration
is determined.
Added comments to ADC defines with Pin numbers.
Added the GPIO_HW_{REV:VER}_DRIVE signals
Define the GPIO_nPOWER_IN_{A:C] and assign them to
BRICK1, BRICK2 and USB Valid.
Regroupped power signals and defined true logic Power Control macros
in the arch agnostic form.
Defined the same IOCTL defines for FMU GPIO IOCTL
Use the power Control macros on board_app_initialize
Moving forward we want all the board configs to drive the
configuration. This is just cleanup to give a clear
example of how ADC should be defined by a simple list,
based on ADC pin number as related to the GPIO and
channel number. Then the xxx_CHANNEL bit are
used to form the ADC_CHANNELS (mask). The GPIO
will are used to for a list for initalization.
