d18e0c3ef8 ahrscomms: Add low-level message code for bootloader msgs
Implement low-level utility functions for sending/receiving
the opahrs proto v0 (bootloader) messages.  These are used
by the OP firmware loader and the AHRS bootloader.

f202884ce8 AHRS: Numerous changes. Added CPU load monitoring for AHRS as well as some friendly debugging output options. Also added a new CalibrationMode setting to AHRS (Echo) to speed up sensor calibration. Cleaned up the 6 point calibration interface to make it more friendly, but I think Edouard will clobber it with something nice and sexy :).

4ca10e92c7 OP-121 OP-122 Flight: Improved USB HID communication.
1. Added reenumeration function and call it on USB init (device will appear after reprogramming now)
  2. Moved buffer.c to general flight/Libraries location
  3. Removed the 62 byte transmission limitation by adding a transmission buffer
  4. Sped up USB communication by increasing endpoint polling frequency

Note, that the nonblocking and blocking USB send functions are not blocking entirely correcting.  The blocking calls the nonblocking, and the nonblocking blocks until the last chunk has started tranmission if it's a big transmission.  The buffering I added would generalize to non-blocking nicely, but would require using the EP1(IN) callback to handle most of the tranmission.  This creates a lot of issues if one function is pushing data onto the buffer and the interrupt is sending.

98822bff98 i2c: force bus free on warm starts
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.

cfd20922cd AHRS: Added the filtered data to the attitude raw object. 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).

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.

840f7ff456 A version of the firmware that successfully Acks back and forth over HID. Still need to refine the PIOS interface and make GCS strip out the report ID data (if necessary). Also note: currently if you run too many modules the watchdog timer kicks in. I haven't determined if this is due to an interrupt binding up or what (and why it doesn't happen more often since I can't find any code that explicitly resets the WWDG).

The AHRS comms module now sync's with the AHRS and
exchanges interesting data periodically.  Whenever
the link to the AHRS is down, the AHRSComms alarm is

This is fairly basic for now but provides the last

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.

514d46f5b6 freertos: fix RTOS API calls from interrupt level
FreeRTOS has a strict requirement that even interrupt-safe API calls (ie.
those ending in "FromISR") can only be called from ISRs that are at lesser
or equal priorities to configMAX_SYSCALL_INTERRUPT_PRIORITY.  See the
"configKERNEL_INTERRUPT_PRIORITY and configMAX_SYSCALL_INTERRUPT_PRIORITY"
section at:
  http://www.freertos.org/a00110.html

The interrupt numbers used on the Cortex-M3 CPU has a somewhat backward
representation of the interrupt numbers so 255 = lowest priority and
0 = highest priority.

The calculation is further complicated by the STM32 implementation only using
the upper 4 bits of the priority value.  Only 0x00, 0x10, 0x20, ..., 0xE0, 0xF0
represent useful interrupt priorities.

FreeRTOS requires that MAX_SYSCALL and KERNEL interrupt priorities are expressed
as raw unshifted 8-bit values to be programmed directly into the BASEPRI register.

The priority values passed to the NVIC initialization, however, are expected
to be 4-bit values and are shifted up by 4 within NVIC_Init() for you.

The end result is that we need this arrangement:

[highest priority]
   NVIC_0 (Non-maskable-interrupt)
   NVIC_1
   NVIC_2
[Must NOT call FreeRTOS APIs above here]
   configMAX_SYSCALL_INTERRUPT_PRIORITY (now at 48 = 0x30 = NVIC_3)
   PIOS_IRQ_PRIO_HIGHEST (cur. NVIC_4)
   PIOS_IRQ_PRIO_HIGH    (cur. NVIC_5)
   PIOS_IRQ_PRIO_MID     (cur. NVIC_8)
   PIOS_IRQ_PRIO_LOW     (cur. NVIC_12)
   configKERNEL_INTERRUPT_PRIORITY (240 = 0xF0 = NVIC_15)
[lowest priority]

The previous config had configMAX_SYSCALL_INTERRUPT_PRIORITY set at
191 (0xBF) which is effectively NVIC_11.  This was allowing all of
the MID, HIGH and HIGHEST interrupt handlers to preempt the OS in
its critical sections.  Since some of these ISRs were calling
FreeRTOS APIs, this would result in corrupting internal data structures
within the OS.

It should be ok to move the configKERNEL_INTERRUPT_PRIORITY to a higher
priority as long as it is less than configMAX_SYSCALL_INTERRUPT_PRIORITY.
