cdb8aa37a0 ahrs: Only read mag data when it has been updated
The AHRS mainloop was reading the mag data on every
loop regardless of whether new data was actually
available.  Now that the MAG_DRDY signal is monitored,
we can read only at the rate (10Hz) new data is actually
produced by the sensor.

This also enables future improvements that will remove the
filtering work that is still being done on the mag data on
every iteration.

59758122e1 AHRS: Cannot process messages while idling as this makes the main loop execution time non-deterministic based on OP (i.e. could get three messages and push the time up). It would be a nice featuer since you can get a raw and EKF update in the same step, but if the AHRS_Comm loop is fast (which is should be to keep update latency low) then this will hammer the AHRS with redunant requests.

80c92ba54b ahrs: process SPI messages while idle
This makes the AHRS continually process SPI messages
while waiting for new samples to be ready.  This has
the side effect of making the CPU utilization on the
AHRS pin at 99-100% (ie. we make use of all of our
otherwise idle time).

Even though this seems like an oxymoron it's still raw to the EKF algorithm, and nice to see the real values after filtering to make sure nothing weird is going on. However, if people don't like this I'm open to suggestions/patches. I'd maybe suggest the whole attituderaw object be converted to ahrsraw anyway since it's more like that (eg. none of the values are actually attitude estimates).

4cba4929c2 AHRS: Fixed another bug in decimation code - I stupidly used Matlab 1 based indexing. Adjusted timing of AHRS so it can process all the data and doesn't miss updates. Finally adjust all inputs to INS to have correct sign and orientation (I think). This is X is forward, Y is right, and Z is down which is mentioned in the forum as our standard and fits the algorithm. The magnetic sensor driver should be modified to return in this order (currently reads X,Y,Z registers which maps to left, back, up) but maybe since it's a board dependent orientation it's better where it is.

d4c5dba234 [PIOS] The ADC mappings are strange because of the way the DMA engine works. Basically data is packed 16 bits ADC2 then 16 bits ADC1 channels, so the accels are pins [4 2 0] currently. Also there is inconsistency between the names of the pins in the config file which uses 1 based indexing and the index for PIOS_ADC_PinGet which is zero based and has to account for this interleaving. Probably should adjust config file to be zero based and then to make those pin numbers map to the function call. The actual order they appear is arbitrary as the ADC engine can scan in whatever order.

f74c6ffdd5 i2c: rewrite i2c layer
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.

a3a2dbd634 spi: Add support for hardware CRC generation/checking
PIOS SPI devices may now make use of automatic CRC generation
and checking on block transfers.  Only supports CRC8 for now.

Since the SPI interface CRC calculation continues across message
boundaries (ie. not reset on every transfer), we must manually reset
the CRC registers for every transfer to allow the two sides of the
link to resynchronize.

Unfortunately, resetting the CRC registers requires disabling the
SPI peripheral which must now be done on every block transfer.

Note: The last byte of the tx buffer is never sent and is assumed to
      be a place holder for the tx CRC8.
Note: The last byte of the rx buffer is expected to hold the rx CRC8.

0e6294ca27 spi: remove internal pull-up from input data lines
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.

e3824a6d78 ahrs spi: Add AHRS SPI link management FSM
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.

The v1 messages are to be used by the main application.

Note: This is not the final protocol definition.

3eceef43d3 spi: Connect device specific DMA IRQ handlers
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.

Converted the board specific configuration for the PIOS SPI layer to

SPI interface between the OP board and the AHRS is now operational at
a basic level, capable of moving simple single byte messages between
boards.  Multi-byte, CRC protected messages will be added on top of this.
