Actuator did not provide an option to completely shutdown selected channels
(set PWM pulse = 0). It is useful for camera stabilization boot delay (we
want few seconds of gimbal servo inactivity to calibrate gyros). It also
might be useful for failsafe on some channels. This option is now available.
It is used to disable camera outputs during fixed 7s delay after boot
instead of setting them to minimum position.
As a side effect, few bugs are fixed (ticks should be multiplied by
portTICK_RATE_MS, not divided, to get time in ms). And few floating point
operations were optimized out as well.
ActuatorCommand.UpdateTime was promoted to uint16 because it is not unusual
to have it 20000ms during flash updates (was seen on the CC after UAV
settings import). So it should be 16bit as well.
This is a partial rework of Cossacs' camera gimbal software.
This patch adds LPF to airframe attitude used for camera stabilisation
and feed forward for camera actuators. Either of options can be
disabled on the compilation level to save flash and RAM if not
required.
Original Cossacs' code was optimized and code flow shortcuts were
added where applicable.
Some modules are written such that they can be included
or excluded at runtime. These are added to the OPTMODULES
list in the makefile for a given board.
This change provides a mechanism to allow a build to force
a given module to be built-in (ie. always initialized)
regardless of the configuration in hwsettings.
The main use case for this is to handle a module being optional
on one platform but essential on another.
All modules added to the MODULES list in the Makefile will
automatically result in a matching #define in the form
MODULE_TheModuleName_BUILTIN
being defined in the CFLAGS for all compiled source.
Note that the capitalization of TheModuleName must match
exactly the capitalization used in the MODULES list.
This patch is based on work of Crubier (LPF) and Cossacs (AxisLock mode).
I've just reworked it a bit by adding a dynamic memory allocation for
static module data.
