The Attitude module will soon be handling updates for all UAVObjects
that require data from the AHRS. To reflect this expansion of scope,
it has been renamed to AHRSComms.

This object currently only holds the serial number of the attached
AHRS board. This will be retrieved each time communications are
(re)established with the AHRS board.
This will eventually be extended to hold some statistics for OP to
AHRS comms.

This object currently holds only the raw magnetometer readings and
an instantaneous heading calculation which are only really useful
for debugging. The contents of this object will change often as
development progresses.
Note: The magnetometer values are often garbage due to a problem
with i2c software on the AHRS.

The input data lines between the OP and AHRS boards had internal
pull-ups enabled. This seemed to be causing issues early on
during development of the inter-board comms. Not sure if this
is still necessary but this is how the current code was tested.

To the outside world, the AHRS can be in one of only a few
primary states:
Not present - AHRS is absent or non-responsive via SPI
Inactive - Only link-level status messages are processed
Ready - Ready to receive the next application level message
Busy - Application level message is being processed
Internal to the AHRS, there are many more states that need to be
managed. This FSM provides the necessary decoupling between the
ISR (which is being driven by the SPI link) and the AHRS main
processing loop which must continue to run its filters independently
of the SPI messaging rate.
With this structure, SPI messages can be received at any time but
processed at only specific points within the filter chains.
git-svn-id: svn://svn.openpilot.org/OpenPilot/trunk@1005 ebee16cc-31ac-478f-84a7-5cbb03baadba
This defines the SPI message format as well as a few
initial messages for moving data across the link.
The v0 messages are place holders for firmware download
in the bootloader.
The v1 messages are to be used by the main application.
Note: This is not the final protocol definition.
Subject to change without notice.

Mark the device specific DMA IRQ handlers as strongly linked
aliases for the genericly named interrupt vector symbol.
Here's how this works...
* The address of the symbol DMA1_Channel2_IRQHandler is written
into the DMA1/Channel2 interrupt vector by the linker script.
* The startup_*.S file specifies Default_Handler() as a weakly
linked alias for DMA1_Channel2_IRQHandler.
* We now override the weakly linked alias with the strongly linked
PIOS_SPI_sdcard_irq_handler().
* This results in the address of PIOS_SPI_sdcard_irq_handler() being
written to the vector table for the DMA1/Channel2 interrupt.
* The PIOS_SPI_sdcard_irq_handler() function is now called whenever
the DMA1/Channel2 interrupt fires.

The AHRSComms alarm will be raised whenever the OP board
is not able to communicate with the AHRS board.
The navigation software on the OP board could use this
alarm to trigger its best attempt at an emergency landing.

The com layer transmit functions should provide guarantees
that they will not modify the buffer that you're transmitting.
Declaring the parameter as a pointer to const keeps the underlying
implementations honest.

The sequence number field for the attitude solution is
likely unnecessary. Removed.

TransferByte API is simplified to either assert or
return the rx byte.

SD R1 response format is defined as any byte with the MSb
cleared. The code was testing for any byte that was not 0xFF
which can lead to misinterpreting a byte as the response.

- created temporary branch of OpenPilot (OpenPilot.posix) in order to test multi platform changes on hardware before committing to the main branch

Fixes to some provider strings.
Changes to static libs needs rebuild.

There is still an issue with this plugin where it will crash if no model is selected, this is not a work-around and that issue needs resolving. However this does mean that it will not meet that issue by default (as is the case now) as it will default to the Easystar.

Setting up to move the data under share back one level, both in the source and the build. Part of work on the installer and nightly builds.

As always please PM me if things are wrong or missing, I know there are other projects that need to be added we use as well.
