Lucas De Marchi a66a201bf5 AP_Compass: HMC5843: Add support for MPU6000 auxiliary bus 
Allow HMC5843 to be on MPU6000's auxiliary bus.
 2015-08-28 12:39:09 +10:00
Lucas De Marchi 628e446e3e AP_Compass: HMC5843: use a struct for raw value 
Like is done in AK8963, declare a raw_value struct.
 2015-08-28 12:39:09 +10:00
Lucas De Marchi 9ecd1daf81 AP_Compass: HMC5843: remove useless delay 
There's no need to add a delay after suspending timer in the
initialization. Also initialize _bus_sem earlier, like is done in
AK8963.
 2015-08-28 12:39:09 +10:00
Lucas De Marchi c66c9c41f2 AP_Compass: HMC5843: be agnostic to I2C bus 
Like was done to inertial AK8963 and inertial sensor move the decision
regarding the I2C bus to the caller. We don't allow changing the address
because apparently HMC5843 doesn't support different addresses.

Changing only the bus could be more easily done but this prepares the
ground for using HMC5843 on an AuxiliarBus.

The need for a more generic abstraction is evidenced by this commit: a
"SerialBus" in AP_HAL would be a nice addition rather than letting each
driver to provide its own. However the methods are a little bit
different from what we have in AK8963. It's safer to do the simple
conversion now and later on to add the abstraction changing everybody to
use it.

Staroselskii Georgii 3eb6be64c9 AP_Compass: ignore first two readings in a clearer way 
This way we don't mix two different conditionals: settling and data validation.
 2015-08-28 12:39:09 +10:00
Staroselskii Georgii 633330db14 AP_Compass: rename calibration array in HMC 
I think naming the variable "scaling" makes more sense.

Lucas De Marchi f61386ae43 AP_Compass: HMC5843: release the lock before read 
read() calls accumulate() which takes the lock by itself so we must
release it like we were doing before 669ae26 ("AP_Compass: encapsulated
calibration in HMC").

Declare a common constructor that others can call.
 2015-08-28 12:39:08 +10:00
Lucas De Marchi a5df93bf10 AP_Compass: AK8963: be agnostic to I2C bus/address 
This decision is better made by the caller rather than polluting the
driver with board-specific details.
 2015-08-28 12:39:08 +10:00
Lucas De Marchi d92c2ac9f5 AP_Compass: pass backend instead of pointer to function 
Just like was done for inertial sensor, different detect() functions
might need different arguments and passing a pointer to function here is
cumbersome. For example, it forces to have a method like "detect_i2c2"
rather than allowing hal.i2c2 to be passed as parameter.

Lucas De Marchi 7e997564bf AP_Compass: standardize inclusion of libaries headers 
Do the missing header changes due to changing the code before the pr
getting accepted.
 2015-08-18 17:12:51 +10:00
Andrew Tridgell 69a86a78a6 AP_Compass: removed AVR1280 specific ifdef 2015-08-11 16:47:41 +10:00
Gustavo Jose de Sousa 58f300e78e AP_Compass: standardize inclusion of libaries headers 
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Randy Mackay 66469d7529 Compass_HMC5843: remove unnecessary i2c semaphore give 2015-08-07 15:50:36 +09:00
Julien BERAUD 39b42a4e6e AP_Compass_AK8963: suspend timer while reading 
Protection in case a timer falls while reading data, because it could end up
with corrupted data
 2015-08-03 22:50:08 +09:00
Julien BERAUD 0aa2fe7a0b AP_Compass_AK8963: fix sem handling 
In case of error or zeroed data, the i2c semaphore wasn't given.
It happened at first startup on Bebop and caused a failure:
"PANIC: failed to take _bus->sem 100 times in a row..."
 2015-08-03 20:57:46 +09:00
Lucas De Marchi 8240e5ae65 AP_Compass: AK8963: reduce bytes read 
We are not using INFO and ST1 registers, so there's no need to read
extra 2 bytes for each transaction.
 2015-07-23 17:44:36 +10:00
Lucas De Marchi 2b9c46e1ff AP_Compass: AK8963: don't oversample AK8963 
Reduce the frequency with which MPU9250 reads AK8963 to reduce the
chance of errors.
 2015-07-23 17:44:36 +10:00
Lucas De Marchi 6c2ceea165 AP_Compass: AK8963: remove author and connection comment 
Authorship and how sensor is connected get outdated (as it already is).
Our code is on git so let it track who wrote each line.
 2015-07-23 17:44:36 +10:00
Staroselskii Georgii 8ab33c46ce AP_Compass: revisited AK8963 code 
Reduced duplication a bit and revisited the update method which is now
split into several logical hunks.
 2015-07-23 17:44:36 +10:00
Lucas De Marchi fffedae3e0 AP_Compass: AK8963: reduce stack usage and zero out buffers 
Since we are not using MPU9250's fifo to get samples from AK8963 we will
always read only 1 sample (+ control registers).
 2015-07-23 17:44:35 +10:00
Lucas De Marchi 37734886a5 AP_Compass: AK8963: remove repeated comments 
No need to repeat the same comments on 3 different places. Instead add a
single comment to explain how start_measurements() and read_raw() are
related.
 2015-07-23 17:44:35 +10:00
Lucas De Marchi 27d95b67a8 AP_Compass: AK8963: remove state machine 
Don't use a state machine in AK8963: the start_measurements() method
should be called only once.  Even if there's a magnetic sensor overflow
the only thing we should do is to discard the new data.

This also moves the _collect_samples() method to be inside _update()
since it's the only place it should be called from, the one running on
the timer thread.
 2015-07-23 17:44:35 +10:00
Lucas De Marchi e232543fca AP_Compass: AK8963: change initialization and rename methods 
We need to check the AK8963's id before anything else Here we are
reordering the calls to _calibrate() and _check_id(). After that we
don't need to read and write again the AK8963_CNTL1 register.

While at it do some renames as well:
	- _configure() -> _setup_mode(): since now there's a
 	  _bus->configure() it became confusing what actually it's
	  doing.
	- make error messages say what we were actually trying to do but
	  couldn't. Also remove PSTR since this is linux-only.
	- start_conversion() -> start_measurements():  We are instructing the
          bus to start to get the samples, not to tell the chip to start an
          analog->digital conversion like in other sensors.
 2015-07-23 17:44:35 +10:00
Lucas De Marchi ae5d9baddb AP_Compass: AK8963: remove defines not used anymore 
The MPUREG_PWR_MGMT_1 defines were used when we cared about the MPU9250
initialization code. Now all initialization is done by the MPU9250 class
itself, so remove these defines.

Also remove AK8983_SELFTEST_MAGNETIC_FIELD_ON that is never used and let
the defines always with 2 bytes to improve readability.
 2015-07-23 17:44:34 +10:00
Lucas De Marchi cae895bfdf AP_Compass: AK8963: group members together 
Besides being semantically related, this removes the hole due to
alignment. The size is the same since the hole is actually turned into
padding.
 2015-07-23 17:44:34 +10:00
Lucas De Marchi 28d3d775a4 AP_Compass: AK8963: remove resolution member 
We only use the highest one and there's no intention to support the
14bits one. Just use the define rather than saving it as a member.
 2015-07-23 17:44:34 +10:00
Lucas De Marchi 86b3312112 AP_Compass: AK8963: factor out common code of read_raw() 
Similar code was added in the read_raw() implementation for each bus.
Add a new POD struct read_raw to contain the registers from the AK8963
and use it instead as argument.
 2015-07-23 17:44:33 +10:00

Staroselskii Georgii 26c8007c96 AP_Compass: updated backend detect method 
Uses reimplemented AK8963 driver. There's also no need trying to detect this
compass twice. Actually, it might even be bad, because the current code can
allocate an AK8963 object twice.

Matthew Lloyd 60a4f74de6 AP_Compass: avoid division by zero if we haven't received any mag reports 
Otherwise, get_field() will return NaNs after once every few calls to
read() during compassmot on PX4 platforms, which causes compassmot to fail.

This is a quick hack around the deeper issue, which could be something
like the PX4 mag driver experiencing starvation and skipping mag reports,
buffer overrun or something else that causes mag reports to be dropped.
Or perhaps we should never expect in the first place that we will always
receive at least one mag report between calls to read().

Andrew Tridgell e4d28b12e5 Compass: remove the need to call calculate() on the compass object 
the new AHRS code doesn't use calculate() and the compass.heading
attribute. Instead it works on the raw magnetometer vector. This
change removes the internal calculate state from the compass object
and instead adds calculate_heading() for use by older code that
doesn't go via AHRS.

This significantly reduces the calculation involved in compass updates

The null offsets enable/disable code is also removed, as it is not
needed now that compass offsets are not linked to the AHRS state.

offsets once they are confirmed to be good, and for learning offsets
without using them in flights.

The default is to behave the same as previously, which is
COMPASS_LEARN=1 and COMPASS_USE=1

Doug Weibel e22a83eec0 Add a CLI setup action to reset the magnetometer offsets 
Since the magnetometer offsets are not available through the MAVLink parameter interface (since they are an AP_Var vector) this little feature allows them to be reset from the CLI.  Useful if you somehow get bad offsets or if you change magnetometer.  If you have a bad set of large offset values I have seen issues with the nulling algorithm have trouble converging to the proper values.  I have never seen it have trouble converging from 0/0/0, so this could be a useful feature from time to time.

Doug Weibel 9846822748 Bug fix for compass. 
This is a fix for an interesting bug when a DCM matrix reset was added to the ground start.  This bug only showed up if (A) a ground start were performed after an air start or due to use of the "Calibrate Gryo" action, (B) if the current orientation were sufficiently different from 0/0/0, and (C.) if the particular magnetometer had sufficiently large offsets.  Why did resetting the DCM matrix to 0/0/0 pitch/roll/yaw at ground start cause a bug?  The magnetometer offset nulling determines the proper offsets for the magnetometer by comparing the observed change in the magnetic field vector with the expected change due to rotation as calculated from the rotation in the DCM matrix.  This comparison is made at 10Hz, and then filtered with a weight based on the amount of rotation to estimate the offsets. Normally it would take considerable time at normal in-flight rotation rates for the offset estimate to converge. 

If a DCM matrix reset occurs when the offset nulling algorithm is up and running, the algorithm sees the DCM reset as a instantaneous rotation, however the magnetic field vector did not change at all.  Under certain conditions the algorithm would interpret this as indicating that the offset(s) should be very large.  Since the "rotation" could also have been large the filter weighting would be large and it was possible for a large erroneous estimate of the offset(s) to be made based on this single (bad) data point.

To fix this bug methods were added to the compass object to start and stop the offset nulling algorithm.  Further, when the algorithm is started, it is set up to get fresh samples.  The DCM matrix reset method now calls these new methods to stop the offset nulling before resetting the matrix, and resume after the matrix has been reset.

this changes the calibration code to require at least 5 good reads
from the compass during initialisation. The calibration is taken as

This also fixes the expected values for the 3 axes for the 5883 to
match reality.

We also save a bit of code space by adding a common rotate_for_5883L()
routine.
