Saves a further 8 bytes of RAM per object.
Saves 1.5KB of flash by removing all of the const strings for
all of the object names and the corresponding meta object names.
This leaves room for more code.
The simposix target uses SIGUSR1 extensively as an
internal signal. This setup file makes sure that
SIGUSR1 doesn't break into gdb every time it is used.
PIOS_Flash_Jedec_EraseChip is called during early
init when the table_magic has changed. This call
happens on CC/CC3D prior to the OS being initialized
so it is not OK to call vTaskDelay() yet.
This was leading to boards locking up (no flashing blue
LED) immediately after jumping to the application when
the table_magic had changed or was being init'd for the
very first time.
Refactored the updating of ChannelUpdateFreq so that it is done only when the actual update rates changes.
The actual update of the servo channel is moved inside the ActuatorTask.
Now the problem happen only in very few cases when modifying update rates.
It is now possible to have 1 to 6 flight mode switch positions
(usefull for guidance, position hold and similar use).
The input channel range is divided into N (1 to 6) zones and each
zone represents a flight mode. Default is 3 zones (backward compatible),
but more can be chosen.
How to use: configure Tx mixers in a way they provide required number
of different values for the same FlightMode channel. For instance,
using Turnigy 9X radio with ER9X firmware, one can create a mixer like
this:
-100 MAX ID0 Manual
R -50 MAX ID1 Stabilized1 (Rate)
R 0 MAX ID2 Stabilized2 (Attitude)
R 50 MAX RUD PositionHold
R 100 MAX ELE ReturnToBase
And set number of flight mode positions to 5. As a result, the 3-pos
switch (ID0, ID1, ID2) will provide first three flight modes, the rudder
D/R switch will override those and enable the 4th flight mode, and
elevator D/R switch will have highest precedence and activate the 5th
flight mode.
This will change the ManualControlSettings objectID.
When building the various all_* targets, it was hard to tell which
board/build-type that each line of output applied to. Now, the
all_* target types will include something like:
CC [fw|cc ] flight/PiOS/STM32F10x/pios_gpio.c
which includes the necessary additional context.
This will help with identifying the context for warnings and errors
when building a group of targets.

flash so it says completed. However, it still blocks the system for a long
time. During an erase the heartbeat will flash at 10 Hz to indicate what's
happening.
This still blocks telemetry even after lowering hte system priority (and there
is a vTaskDelay) which makes me think that the SPI bus being locked is blocking
Sensors or somethign else. This should not be permited when the system is
armed.
The reason the system locks up during the erase is that the file system
operations occur within the event dispatcher thread. It is very bad practice
for anything to block this (i.e. callbacks should never take very long). We
should probably move the object persistence handling into the system thread or
something but that can be a separate issue.
seems apply a leaky integrator to the swash angle. This is the similar to what
is done by Phubar (http://code.google.com/p/phubar/) as well although we refer
to the gyro term as the proportional and the flybar angle as the integral
LED support was dropped from the BU images due to a lack
of proper abstraction for LED definitions between CC and
CC3D HW variants in the CopterControl board family.
Use the new LED abstraction to hide board revision details
from the BU image so it can once again flash some LEDs.
Every board has at least one LED (HEARTBEAT). Not all
users of LEDs need to be directly aware of which LED
configuration to choose when there may be more than one
possible configuration.
Hide the details of the differences between LEDs used in the
different HW revs for CC. This will allow generic code to
run on CC and CC3D without being exposed to the details of
the different pins used for the LEDs.
CC and CC3D boards share the same FW image. This is accomplished
by checking the BOARD_REVISION field in the board_info_blob
that is stored in the BL partition in flash as we init the FW.
Make sure that the BU image only writes a BL image that has
the same BOARD_TYPE and BOARD_REVISION fields in the embedded
image as the ones currently in flash on the board.
This ensures that we never write a CC3D BL image onto a CC board
and vice versa. This check should prevent "bricking" a board.
The bootloader needs to understand whether the USB cable
is connected. The HID and CDC drivers need to know if
the cable is connected _and_ the device has been enumerated
already. Separate these two concepts in the API.
Combining these was resulting in the BL not properly
detecting that the cable was plugged in, and trying to boot
the firmware image immediately. This effectively bricked
the board if you ever had an invalid firmware image.
It also happens to be the case that the BU images automatically
invalidate themselves after updating the BL so they don't run
again. The cable detect bug + this intended behaviour of the
BU image resulted in a bricked board after upgrading the BL.
USB device was being accessed prior to being initialized.
This resulted in a hard-fault or NMI when using any endpoint
beyond 0 or 1 which are init'ed by the BL. This broke VCP which
is on endpoint 2 (control) and 3 (data).
This bug was introduced in 5ad37e69 which stopped checking the
transfer_possible variable.
Use new PIOS_USB_UTIL_AsciiToUtf8() function to compose the
USB serial number rather than repeating that code for each
board.
All boards now append "+FW" or "+BL" to their USB serial numbers
to allow the descriptors to differ between FW and BL images.
Some versions of Windows will ignore the USB device serial number
if the string is not delivered with LANGID = English US 0x0409.
This is true regardless of the configured locale of the machine.
The serial number string descriptor was incorrectly null
terminated. The standard clearly states that there should
not be a null terminator.
Use new #defines to ensure that our strings are sized
properly.
BL images now always use hid-only.
FW images can use hid-only or hid+vcp but this is selected
ONLY at compile time based on whether PIOS_INCLUDE_USB_CDC
is defined.
CC uses HID+VCP by default now.
This makes the BL and FW images distinct devices with unique
serial numbers.
Windows (and maybe Mac) remembers the device descriptors and
the associated drivers based on this serial number. Providing
unique serial numbers for the BL and FW images allows us to
provide different sets of descriptors for the BL and FW images
without confusing these OSes.
BL version number is now also bumped to reflect the new
serial number generation algorithm.
Now that we have a USB descriptor for HID+VCP that works
on Ubuntu 11.10, MacOS 10.7.3, Win7-SP1-32bit,
WinXP-SP3-32bit, Win7-SP1-64bit.
VCP is known to not work on WinXP without service pack 3.
