- no longer start sercon or mavlink usb by default
- on USB connection (VBUS) monitor serial USB at low rate and start Mavlink if there's a HEARTBEAT or nshterm on 3 consecutive carriage returns
- the mavlink USB instance is automatically stopped and serdis executed if USB is disconnected
- skipping Mavlink USB (and sercon) saves a considerable amount of memory on older boards
Using mixers on the IO side had a remote benefit of being able to
override all control surfaces with a radio remote on a fixed wing.
This ended up not being used that much and since the original design
10 years ago (2011) we have been able to convince ourselves that the
overall system stability is at a level where this marginal benefit,
which is not present on multicopters, is not worth the hazzle.

The clock is simply not accurate enough to do that.
Plus the measuring overhead is much higher than the executed instruction.
Remaining issue: memory transfers (due to volatile) add non-negligible
overhead and distort the result. Could be solved by using inline assembly.
Only needed for Makefile-based builds:
gmake[3]: *** No rule to make target 'src/modules/flight_mode_manager/FlightTasks_generated.hpp', needed by 'events/px4.json'. Stop.
- sending protocol
- uorb event message & template methods for argument packing
- libevents submodule to send common events and handle json files
- cmake maintains a list of all (PX4) source files for the current build
(PX4 modules + libs), which is used to extract event metadata and
generate a json file
PX4 uses banks of 8 outputs as a logical structure. Boards that have
more outputs than 8 get multiple instances. This is an arbitrary choice
that helps with overall structure and enables the mixing of different
device classes (like FMU, IO or UAVCAN).
This system command will display, set and save the network
settings.
netman show - Displays the current settings.
netman update - Will check for a net.cfg file on the SD card.
If present, it will update the paramaters,
delete the file, and reboot. Using the new settings.
netman save - Saves the current settings to net.cfg on the SD card.
This file shoulf be renamed to preserver it across
reboots or editited to chech networkin paramates.
File format is name<space>value:
echo DEVICE=eth0 > /fs/microsd/net.cfg
echo BOOTPROTO=fallback >> /fs/microsd/net.cfg
echo IPADDR=192.168.0.4 >> /fs/microsd/net.cfg
echo NETMASK=255.255.255.0 >>/fs/microsd/net.cfg
echo ROUTER=192.168.0.254 >>/fs/microsd/net.cfg
echo DNS=192.168.0.254 >>/fs/microsd/net.cfg
Valid values for `proto` are `dhcp`, `static`, `falback`
Both will try dhcp for CONFIG_NETINIT_FALLBACK times
and fall back to the static address.
NETMASK - is the network mask.
IPADDR - this nodes ip address for static or fall back.
ROUTER - The default route.
DNS - The address of the dns server.
This is in no way a complete test suite but is intended as a starting point to get minimal
test coverage for CLI handling tests in. This is necessary to QA the CLI handling
(e.g. removal of commands) and to ensure that we are exercising these code paths in
stack check and alike tests.
