murata 974d63a6b5 AP_HAL: Change the format of the return value of the method header. 2017-01-09 15:46:03 +00:00
Andrew Tridgell da45aef5c6 AP_HAL: fixed a logic bug in the srxl state machine 
when decoding invalid input the buflen could grow to beyond the buffer
size, overwriting the next block of memory. On Disco this ended up
overwriting the Perf::_instance variable, which led to a segmentation
fault
 2017-01-09 09:14:13 +11:00
Randy Mackay a2f6d7c102 AP_HAL: minor comment fix to Device.h 2016-12-24 13:55:31 +09:00

mirkix 7e33ba04a9 AP_HAL: Add BBBmini PX4FLOW I2C bus number 2016-12-03 21:07:07 +11:00
Andrew Tridgell 28a318145c AP_HAL: move set_retries() up to Device class 
we really need set_retries() high during init for nearly all i2c
devices, and as many are written against the generic device class
moving it to the Device class makes this a lot easier. It is a NOP on
SPI.
 2016-12-02 09:47:51 +11:00
Andrew Tridgell fac8f1db03 AP_HAL: added MODE_PWM_BRUSHED16KHZ 2016-11-30 10:53:25 +11:00

Andrew Tridgell 1990aa96e1 AP_HAL: added get_bus_id_devtype() 
used to do versioning on device types
 2016-11-09 17:08:06 +11:00
Andrew Tridgell 3d48b6bb3a AP_HAL: added device id tuples to Device class 
this allows a bus connection and device type tuple to be identifed as
a 24 bit number for use in user visible device IDs. Every bus
connection has a unique device ID.
 2016-11-09 17:08:04 +11:00

Lucas De Marchi 7968736b1c AP_HAL: add O_CLOEXEC in places missing it 
By opening with O_CLOEXEC we make sure we don't leak the file descriptor
when we are exec'ing or calling out subprograms. Right now we currently
don't do it so there's no harm, but it's good practice in Linux to have
it.
 2016-11-07 12:37:30 -03:00
Lucas De Marchi 312a27dd20 AP_HAL: RCInput: rename deinit() to teardown() 2016-11-02 16:28:20 -02:00

Andrew Tridgell e356797888 AP_HAL: make cork() mandatory in RCOutput 2016-10-13 10:00:04 +11:00
Lucas De Marchi ae53920e5b build: don't build examples with old build system 
We currently check examples are buildable with waf which doesn't need
the libraries to be specified in a make.inc file.  Having the makefiles
there is misleading since people try to build and realize the build is
broken.
 2016-10-11 13:03:08 +11:00
Andy Little 4b2eedac05 AP_HAL: Split the AP_HAL_Boards.h header into per board sub headers for legibility 2016-09-29 08:26:50 -03:00

Gustavo Jose de Sousa 5c5ddc9d4a AP_HAL: reformat AP_HAL_Boards.h 
The definitions for each board haven't been reformatted here. They need a
little more thinking on how to format them in order to provide better
readability.
 2016-09-03 01:03:17 -03:00
José Roberto de Souza 0b0be31a29 AP_HAL: add defines for Intel Aero 2016-09-03 01:03:07 -03:00
Lucas De Marchi e1ab44f4a3 Global: remove get_fd() from Device API 
This was there for compatibility with I2CDriver and SPIDriver. We don't
use them anymore so we can remove the compat method.
 2016-08-29 10:27:36 -03:00
Lucas De Marchi ead01855df AP_HAL: remove default params for minlure 
We are currently not using them.

LukeMike 13e3150023 VRBRAIN / AP_HAL_Boards: definition of new board VR Brain 5.4 and VR Core 1.0 2016-08-07 20:31:51 +10:00
Murilo Belluzzo 077e03678f Global: Adapt Stream class to be used with Ringbuffer 2016-08-03 01:44:02 -03:00
Murilo Belluzzo b856d26087 RingBuffer: ::set_size now returns true or false 2016-08-03 01:44:02 -03:00
Murilo Belluzzo f7f203efa9 RingBuffer: Add ::clear() method to discard the buffer content 
The same could be achieved with ::set_size(::get_size()), but was not
obvious and hurts code readability.
 2016-08-03 01:44:02 -03:00
Murilo Belluzzo 75a1b102fb RingBuffer: Handle zero sized better 
Sometimes (like in DataFlash) the size of the ring buffer will be
determined in run time and the object can have size zero until proper
initialization. When this was the case, an underflow in ::get_size would
mess with the initializing algorithm.

Another issue was that the 'new' operator could fail what was not being
handled. Now, we only set the size member after we are sure 'new'
successfully allocated memory.

Lucas De Marchi 37de995960 AP_HAL: update Device interface for periodic tasks 
Replace the previous not-implemented interface with a set of new methods
that can be resonably implemented:

    - register_periodic_callback() now receives a functor returning bool
      to easily allow "oneshot" timers

    - adjust_periodic_callback() allows the caller to change the timer
      for a specific handle. This way drivers like MS5611 can adjust the
      timer depending on its state machine: the time to sample
      temperature is smaller than the time to get a pressure sample

    - add unregister_callback(): since we have an opaque pointer, we
      can't tell the user to just delete it in order to unregister the
      callback

Murilo Belluzzo 3e1acdcbbf AP_HAL: Use atomic instead volatile on RingBuffer head/tail 
Volatile will provide protection to sequence re-ordering and guarantee
the variable is fetched from memory, but it won't provide the memory
barrier needed to ensure that no re-ordering (by either the compiler or
the CPU) will happen among other threads of execution
accessing the same variables.

For more info about this effect can be found on articles about
std::memory_order.

Murilo Belluzzo b7dd4dad64 AP_HAL: Fix ByteBuffer::reserve() breaking buffer state 
When using reserved(), the reserved memory cannot be read before it's
written, therefore we cannot update 'tail' until the caller of
reserved() is done writing.

To solve that, a method called 'commit()' was added so the caller can
inform that is done with the memory usage and is safe to update 'tail'.
The caller also has to inform the length that was actually written.

This solution was developed to work considering the usage context of
this class: 1 reader and 1 writer **only**.

Leandro Pereira fbefe32017 AP_HAL: Add method to reserve space in the ring buffer 
Adds a method called `reserve()`, that will take a ByteBuffer::IoVec
array of at least two elements, and return the number of elements
filled out.  0 will be returned if `len` is over the total space of
the buffer; 1 will be returned if there's enough contiguous bytes in
the buffer; 2 will be returned if there are two non-contiguous blocks
of memory.

This method is suitable to be used with POSIX system calls such as
readv(), and is an optimization to not require temporary memory copies
while reading from a file descriptor.

Also modify the write() method to use reserve(), so that similar checks
are performed only in one place.
 2016-07-08 13:10:16 -03:00
Leandro Pereira e3b676ba89 AP_HAL: Add method to peek non-contiguous parts of a ByteBuffer 
Modify ByteBuffer class to have a `peekiovec()` method, that takes in a
`struct IoVec` array (similar to `struct iovec` from POSIX), and a
number of bytes, and returns the number of elements from this array
that have been filled out.  It is either 0 (buffer is empty), 1
(there's enough contiguous bytes to read that amount) or 2 (ring buffer
is wrapping around).

This enables using scatter-gather I/O (i.e. writev()), removing calls
to memcpy().  That's one call when no wrap-around is happening, and
two calls if it is.

Also, rewrite `ByteBuffer::peekbytes()` to use `peekiovec()`, so that
some of the checks performed by the former are not replicated in the
latter.

Gustavo Jose de Sousa 66f1ad9ed0 AP_HAL: Device: add support for read flag 
Many of our SPI and I2C sensors define the protocol of setting the most
significant bit of the register address in order to perform a read operation.
Thus, enable the use of a "read flag" that is ORed with the register's address.
Since this is an abstraction for general devices, it's a good idea to have zero
as the default value for that flag.

While at it, add documentation to read_registers().
