Andrew Tridgell 0601259d20 AP_HAL_Linux: removed assert calls 
these waste flash space and do not do us any good

Peter Barker c917cd4dbb AP_HAL_Linux: make a static-const hal references references to external symbol 2020-03-03 10:12:14 +11:00
Andrew Tridgell 67bd4ed396 AP_HAL_Linux: use take_blocking instead of HAL_SEMAPHORE_BLOCK_FOREVER 
this makes for cleaner and smaller code as the failure case is not
needed

Andrew Tridgell 070e3cf37b HAL_Linux: implement I2C bus masks 2018-07-10 15:39:47 +10:00
Andrew Tridgell 43c1bd0ae9 HAL_Linux: fixed I2C get_device() interface 
just stubs for now

Lucas De Marchi 32d208dbe8 AP_HAL_Linux: move check for _split_transfers 
This is likely not true, so allow not to check the other conditions.
Also remove comment since this is going to be added to the method.

Andrew Tridgell a2e445cf24 HAL_Linux: implement set_split_transfers() API for I2C 2017-02-23 22:38:15 -08:00
Andrew Tridgell a6ac02b61f HAL_Linux: implement device IDs for I2C and SPI 2016-11-09 17:08:04 +11:00
Lucas De Marchi fa540429f9 AP_HAL_Linux: allow to teardown bus threads 
Add code to teardown all bus threads. This can be called while exiting
to wait for threads to finalize.

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.

Ralf Ramsauer 71212942da AP_HAL: AP_HAL_Linux: align I2CDevice::read_registers_multiple() 
25c7e8b changed the logic of transfer(). Align
I2CDevice::read_registers_multiple() in the same way.

Ralf Ramsauer 5b81920737 AP_HAL: AP_HAL_Linux: add comment to I2CDevice::transfer() 
If I2CDevice::transfer() has to do nothing it returns false. This can be
misleading, as this might feel contradictory.

Let's spend a comment on that.

Ralf Ramsauer 25c7e8bf60 AP_HAL: AP_HAL_Linux: perfect I2CDevice::transfer() 
According to man 3 ioctl, ioctl returns other values than -1 on success.
So loop while ioctl returns -1.

Furthermore, there is no necessity to initialise r with -EINVAL,

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.

Lucas De Marchi 590539f674 AP_HAL_Linux: implement threaded I2C 2016-07-30 00:55:27 -03:00

Lucas De Marchi 8e5aba8653 AP_HAL_Linux: I2CDevice: move implementation to outside 
As we add methods, it's becoming too complex to be implemented together
with the declaration.

Gustavo Jose de Sousa d35cf60ce1 AP_HAL_Linux: I2CDevice: use read flag in read_registers_multiple 
Use the generic support in Device interface for read flag when we are
using read_registers_multiple() method.

Gustavo Jose de Sousa d615628367 AP_HAL_Linux: I2CDevice: add missing stdio.h include 
This was probably being included by another header, but it's not on
gcc >= 6.1 and glibc 2.23.

Lucas De Marchi 6a6175df1c AP_HAL_Linux: move dirname to I2CDevice core 
All entries would need the "devices/" prefix and it's more natural not
using it.

Lucas De Marchi 5194f7e5ce AP_HAL_Linux: I2CDevice: method to read multiple times 2016-02-16 19:49:09 -02:00
Lucas De Marchi bc2f7f2783 AP_HAL_Linux: implement function to transfer data 
This is a similar function to what we have in I2CDriver, but it can
receive a nullptr to recv or send.  It will create 2 i2c_msg structs to
send and receive data to/from the I2C slave.

Lucas De Marchi 2fc534d18d AP_HAL_Linux: implement methods to open the bus 
These are very similar to their counterparts in I2CDriver. The changes
were:
    - Don't use fixed buffer with PATH_MAX length: allocate the string
    - Change the interface to use std::vector so we can simplify the
      implementation

Lucas De Marchi cd0e1dff82 AP_HAL_Linux: Add skeleton for I2CDevice 
This adds the logic to maintain the I2CDevice's managed by I2CManager.
