Debug code was previously using the q4 element
in the attitude message to encode a cycle counter
to measure performance on the AHRS. This is no
longer valid.

Issues have been reported with CRC errors
on the SPI link between the OP and AHRS
boards. Slowing the link down eliminates
the errors in my testing.
If we speed this link back up in the future,
further investigation will be required to
diagnose the source of the CRC errors.

This object is not yet populated or used. This
will soon hold the raw position data from the GPS
receiver. PositionActual will be converted to
hold the computed position from the AHRS.
Contents of this object are still subject to change.

of a fixed a fixed point encoding for lat/lon.

The transition from the ADDR state to the read state
was broken for non-final reads. The FSM diagram was
also wrong for this transition.
Since reads are always the last transaction in a sequence
in our current usage, this doesn't actually fix any known
bugs.

Since the i2c bus is bidirectional, there are certain
states (eg. part way through a read) where the slave
device is in control of driving the SDA line.
On a cold start (power on), the slave devices are all
quiescent and will not drive the bus. However, on a warm
start (eg. watchdog or jtag restart), it is possible that as
the CPU boots, the slave device may be holding the SDA line
low. This is a bus busy condition and will prevent the I2C
bus master in the CPU from being able to seize the bus during
init.
The fix for this is to clock the i2c bus sufficiently to ensure
that the the slave device finishes its transaction and releases
the bus.
Once the slave has released the bus, the bus master can properly
initialize and assert a STOP condition on the bus.

into NED reference frame and used in the INSGPS algorithm, although currently this
information isn't propagated back to OP. Data structures related to the GPS position
into the algorithm and the position estimate out will likely be in flux.

Eclipse Workspace:
- Made project in Eclipse workspace point to trunk/flight
- Re imported launch configurations from previous version
OpenOCD
- added "ft2232_device_desc "Dual RS232-HS"" back to jtag cfg files because windows didn't like it w/o it.

Altitude/pressure sensor data is sent to the AHRS whenever
the AltitudeActual object is updated.
Altitude, Pressure and Temperature are sent as floats.
Same as in the UAVObject that goes to the GCS.

The STM32 I2C block has a number of errata associated with it.
These errata are primarily related to timing sensitivities between
the peripheral and the interrupt handler. In particular, the
correct generation of the stop bit relies on the I2C IRQ running
immediately and not being held off for any reason.
NOTE: The I2C interrupts must be the highest priority IRQs in the
system to ensure correct operation.
I2C protocol is now implemented as a formal state machine.
See: stm32_i2c_fsm.{dot,jpg} for FSM description.
I2C init is now expressed by const initializers in pios_board.c
for both OP and AHRS boards.
I2C device drivers (ie. bmp085/hmc5843) now pass in const arrays
of an unlimited number of bus transfers to be done atomically.
The I2C adapter driver now handles all bus-level locking across the
list of transactions. Generation of start/restart/stop conditions
are handled automatically over the list of transactions.
Timeouts have been removed from the API for now. May be added
back later.
This driver has run error free on both the OP and AHRS boards for
up to 48hrs but it still sometimes fails earlier than that on the OP
board. There is another possible set of improvements to the driver
that could employ the DMA engine for transfers of >= 2bytes. This
change would reduce the timing sensitivities between the peripheral
and the driver but unfortunately, both the SPI and I2C interfaces
share the DMA1 engine. That means only one of these two peripherals
can use the DMA engine and right now, SPI between OP and AHRS is
already using it.
Failures are currently fatal and will lock up the CPU. This allows
useful information to be obtained in the failure cases.

Mark the I2C_InitStruct parameter as const so that we can pass
const data as the initializer.

The gdb init files would previously reset the target immediately
when gdb started up. This is sometimes an unpleasant side-effect
of running gdb.
In order to connect to the target, use the new "connect" function.
To reset the target use "mon reset".

- syntax error in pios_board_posix.c introduced with Doxygen comment blocks
- platform dependant code had been added to openpilot.c instead of pios_board.c
- redundant header inclusion (stm32... already included by PiOS)

- Added FlighSituation Module (development module for sensor fusion, mostly stub, possibly renamed later)
- Added Navigation Module (development module for navigating towards a point in space - DEVELOPMENT CODE, NOT STABLE YET (I am testing around with this))
- Changed Stabilization Module (uses local reference frame now. Stable except for code cleanup/review. Tested in simulator and outperforms old code.)

1) floss-jtag.arhs.cfg
2) floss-jtag.openpilot.cfg
But the Eclipse project the "external tools configurations" for the OpenOCD Debug is looking for the "floss-jtag.cfg" file in the command line arguments. The added file "floss-jtag.cfg" is a simply a copy of "floss-jtag.openpilot.cfg". The .arhs.cfg doesn't play well by itself.
