Andrew Tridgell 8a1275356d AP_Baro: moved MS5611 reset before prom read
thanks to Jacob and Lucas for pointing this out

Andrew Tridgell eea7758a63 AP_Baro: added GND_EXT_BUS option
this is needed to enable probing for a MS5611 on external I2C bus. The
MS5611 looks the same as a MS5525 airspeed sensor, so we can't just
auto-probe. Users will need to enable external barometers

Andrew Tridgell f2246326bb AP_Baro: added MS5611 probing, and support 3 baros on Pixhawk2
this adds sensor probing for barometers, simplifies the MS5611 driver,
and adds support for the I2C external barometers on Pixhawk2

Andrew Tridgell b16226dddf AP_Baro: fixed a bug with corrupted conversions in MS5611 driver
the datasheet says that if you get back zero in an ADC read that the
next value can be corrupt. I have seen this happen on the FMUv1,
leading to bad altitude readings

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Lucas De Marchi e217faacab AP_Baro: MS56XX: cosmetic changes to members
- reorder and document members.
    - remove tentative of vertical alignement
    - like was done for accumulated values, move the calibration
      values to a struct

Lucas De Marchi f7b453359d AP_Baro: MS56XX: convert to threaded bus
This converts MS56XX to use the thread started by SPI/I2C instead of
using the timer thread. This also fixes a possible starvation of the
main thread:

    1) INS driver registers itself to be sampled on timer thread
    2) MS56XX registers itself to be sampled on timer thread
    3) Main thread waits for a sample from INS with
       ins.wait_for_sample()
    4) timer thread is waiting on update from MS56XX and consequently
       the main thread is waiting on an I2C/SPI transfer

Besides this starvation there's another one due to reuse of the timer
lock in order to pump values from the timer thread to the main thread. A
call to the update() method when we have a sample available would need
to wait on any other driver holding the timer lock.

Now there's a lock just to pass the new values from the bus thread to
the main thread with a very tiny critical region, not waiting on any
bus transfers and/or syscalls.

Lucas De Marchi 929348ff75 AP_Baro: MS5611: always use timer thread
Remove support to run MS5611 on main thread since we shouldn't be doing
I2C transactions there and we are moving to "thread per bus"
nonetheless.

Lucas De Marchi f1ade970a3 AP_Baro: MS5611: Use AP_HAL::Device abstraction
This allows to share almost all the I2C/SPI code and remove the
AP_Serial abstraction since that is now handled by AP_HAL itself.

Lucas De Marchi 9d5fb97819 Global: rename enum SPIDevice to SPIDeviceType
Free the SPIDevice name so to have a consistent name for I2C/SPI device
classes.

Lucas De Marchi 81a298c9c8 AP_Baro: reduce header scope
We don't need to expose to other libraries how each backend is
implemented. AP_Baro.h is the main header, included by other libraries.

Instead of including each backend in the main header, move them to where
they are needed. Additionally standardize the order and how we include
the headers.

The advantages are:
	- Internals of each backend is not exposed outside of the
	  library
	- Faster incremental builds since we don't need to recompile
	  whoever includes AP_Baro.h because a backend changed

Lucas De Marchi 30f631de8f AP_Baro: MS5637: fix CRC check
The configuration of MS5637 is different from MS5611 in 2 ways:

    - The PROM is of 112 bytes rather than 128
    - The CRC is located in the first MSB of the first word, not the
      last one

For CRC calculation we also need to zero out the last (missing) word.

This renames _check_crc() to _read_prom(), which returns false when the
PROM doesn't contain valid data. It also makes it virtual so MS5637 can
override it. This also moves the PROM read to be all in the same place
rather than split between the CRC field and coefficient fields. Finally
calculate_crc() is renamed to crc4() to be shorter and add info on what
it does.

José Roberto de Souza 7457588d7c AP_Baro: Move initialisation code from MS56XX constructor to init()
On MS5637 we will need to override the method to read and calculate the
PROM's crc. Thus we need a 2-phase init.

It also makes the constructor of AP_Baro_MS56XX protected since only the
derived classes should instantiate the base one.

Lucas De Marchi 94d01934f7 AP_Baro: MS5611: reduce OSR to 1024
This is the same change as done in PX4:

	This reduces self-heating of the sensor which reduces the amount
	of altitude change when warming up. Apparently some individual
	sensors are severely affected by this.

	Unfortunately it raises the noise level, but Paul is confident
	it won't be a significant issue.

Lucas De Marchi 4bd8b2ae35 AP_Baro: remove checks for HAL_BOARD_APM2 and HAL_BOARD_APM1 2015-11-04 12:14:11 +11:00
Lucas De Marchi 2c38e31c93 Remove use of PSTR
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.

This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.

AVR-specific places were not changed.

José Roberto de Souza d9931b5f34 AP_Baro: Add support to MS5637
As AVR2560 is not supported anymore and do integer operations is
usually faster than float-point the _calculate() implementation was
done using only integer operations and as more close to what
datasheet says.

Julien BERAUD 3b5d73b1fe AP_Baro_MS5611: Fix state machine in case of error
If there is a read error, reading from the adc will return 0 but moreover,
we need to re-initiate a read or else we are stuck forever.

From MS5611-01BA03 datasheet, p. 10, CONVERSION SEQUENCE:
"After the conversion, using ADC read command the result is clocked out with the MSB first.
If the conversion is not executed before the ADC read command, or the ADC read command is
repeated, it will give 0 as the output result."

Gustavo Jose de Sousa bcd5dff774 AP_Baro: MS56XX: do not change change state on error
If we have an error in the SPI or I2C transaction we should not change
the state. Otherwise we might read a temperature when the sensor is
reporting pressure and vice-versa.

Gustavo Jose de Sousa f18802bc46 AP_Baro: 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.
