Andrew Tridgell 2bab0efc41 HAL_Linux: implement HAL_GPIO_SCRIPT support 
this allows Linux boards to trigger an external script on GPIO
writes. This can be hooked up to relays with either RC options or
mavlink or mission items to trigger actions that can be scripted

Andrew Tridgell 48aacb9462 HAL_Linux: removed use of RCInput_SBUS and RCInput_115200 2019-05-02 17:58:51 +10:00
Andrew Tridgell 1c322d296f HAL_Linux: switch Disco to using AP_RCProtocol library for RCIN 
this is the first step to using AP_RCProtocol for most (or all) RC
input on Linux boards. It also fixes a major bug on Disco where the
old SBUS decoder didn't use strict enough timing checks to filter out
bad frames when video capture is running. That led to erratic flight
mode changes and sometimes loss of control.
 2019-05-02 17:58:51 +10:00
Lucas De Marchi 5520b397c2 AP_HAL_Linux: allow disco to use RCInput_UDP 
This allows to use any device to send RCInput to Disco via network.
Particularly this is useful when paired to additional changes on
SkyController 2 so it can be used to control Ardupilot.

This was tested with https://github.com/lucasdemarchi/dema-rc running
on SkyController 2.

works for Linux boards.

Lucas De Marchi ad8ab97725 AP_HAL_Linux: SPIDevice: compile out debug stuff 
This should at most be behind a flag. If the device is being used by
other process/drivers, it's a problem with that specific user/distro:
don't penalize everybody else. Besides, changing the mode is not atomic
and nothing guarantees the other side doesn't get scheduled and change
it back before we get to run.
 2018-09-08 09:47:33 -07:00
Lucas De Marchi 2c6dd64c67 AP_HAL_Linux: create one thread per spi bus rather than device 
Do not create one thread per chardev (i.e. bus + kernel's chip select).
Since the shared resources are actually the bus controller and the bus
lines, it makes sense to have 1 thread per bus, otherwise it will just
get locked again on the mutex in the kernel side.

Lucas De Marchi cf4fb09881 AP_HAL_Linux: Remove hole from SPIBus

Lucas De Marchi d2446e1219 AP_HAL_Linux: use Thread abstraction to create thread 
The open coded version has the same problem fixed by Thread abstraction:
the order of the calls matters and it's easy to call in the wrong order.
Here pthread_attr_setschedparam() and pthread_attr_setschedpolicy()
should be swapped, like in 62c2f737d5 (AP_HAL_Linux: fix setting RT priorities.)

Lucas De Marchi 49d08ba72a Global: remove minlure 
Minlure is a port of ArduPilot to Minnow Board connected to daughter
board. Very few of those were produced and nobody is flying with it.

It served its purpose and all the the improvements to ArduPilot remain
regardless of it not being supported anymore. Now it's just adding
maintenance work with no clear benefit, so pull the plug.

Lucas De Marchi 88dc17fe6e AP_HAL_Linux: Storage: fix initialization 
Use init() to lazily create/open storage directory and keep fd open

Lucas De Marchi 1f3b7b5687 AP_HAL_Linux: Storage: fix writing garbage while creating file

care by Linux according to the media/fs that is there.

Lucas De Marchi cf3a9cddc8 AP_HAL_Linux: fix build error with flexible array 
Apparently this code came in part from libuavcan that defines this
struct Control. They also had the same issue detailed on
https://github.com/UAVCAN/libuavcan/issues/116.

The solution here is much simpler though: stick to the design of cmsg()
even if it's C. As per cmsg(3), use a union together with CMSG_SPACE().

Removes compile-time selection of RCInput driver for ocpoc_zynq.
PPM and SBUS input are now colocated on the ocpoc board, and it
only needs to run RCInput_ZYNQ. Pulse input is also inverted
to accommodate SBUS input, which has no effect on PPM input.

Georgii Staroselskii d214a36e0a AP_HAL_Linux: reset duty cycle before setting period 
On kernels 4.7+ duty_cycle should always be less than period.
Otherways, we'll get a EINVAL.

It makes sense to set duty_cycle to 0, as
duty_cycle doesn't really make sense without a proper period.

A proper way to handle these errors might be to call pwm_adjust_config
in every pwmchip backend but it's unrealistic to hope that all vendors
will do it quickly.

Lucas De Marchi 4d5aed1d69 AP_HAL_Linux: UARTDevice: never be the controlling terminal 
If we are the controlling terminal for a tty device we will receive a
SIGHUP when the device disappears. Currently what happens is that we
simply stop the whole process. We don't want to fall off the sky due
to a bad device. This can happen for any reason, but it's more likely
if the UART is behind a USB connection.

Lucas De Marchi 5ebc8c2cb3 AP_HAL_Linux: ToneAlarm: ifdef out bogus message 
These messages are only valid in a small subset of Linux boards (those
based on BBB and variants).  The ToneAlarm class should actually be
split allowing different implementations, but for now let's just disable
the message.

Georgii Staroselskii e79fc893fa AP_HAL_Linux: HAL_Linux_Class: delay SPIUARTDriver static initialization 
There's an implicit (apart from the name) dependency between SPI and
SPIUARTDriver which results in a crush on a restart or a shutdown.

By moving the initialization we're making sure that all objects are
deleted in the right order.

Probably better to use OwnPtr around those. But it's better to be done
in a separate PR.

Lucas De Marchi 66a1e420cb AP_HAL_Linux: RCInput_SoloLink: better name to first field 
Checking the time on the tcpdump capture, it matches the first fields
from the data:

$ tshark -n -c 4 -r  ~/tmp/solo/rc.pcap
    1   0.000000     10.1.1.1 → 10.1.1.10    UDP 68 5005 → 5005 Len=26
    2   0.019976     10.1.1.1 → 10.1.1.10    UDP 68 5005 → 5005 Len=26
    3   0.040046     10.1.1.1 → 10.1.1.10    UDP 68 5005 → 5005 Len=26
    4   0.059961     10.1.1.1 → 10.1.1.10    UDP 68 5005 → 5005 Len=26

From the previous commit (first 2 packets):

     5fa8 f441 3414 0500 73d7  dc05 dc05 dc05 db05 e803 e803 e803 f401
     73f6 f441 3414 0500 74d7  dc05 dc05 dc05 db05 e803 e803 e803 f401

0x0005143441f45fa8 - 0x0005143441f4f673 = 0x4E14 = 19988 (usec)

Which seems to approximately match for the other packets as well. We are
not using the field since we rather get the time when we receive it, but
at least use a better name.

Lucas De Marchi e803045d1f AP_HAL_Linux: Scheduler: increase stack for scheduler threads 
RPI-based boards that use RCInput_RPI need more stack space otherwise we
end up with stack corruption. This leads to crash particularly when also
using GPIO_RPI since it may change what that driver is poking on memory.

This increases stack size to 1M which is overkill for most of other
boards with a more controllable stack usage. However this exposes that
on multiple different HWs a single point for stack size decision may not
be the best.  This can be improved in future.
