Scales each channel only based on max and min calibrated values.
The neutral value is now ignored so the joystick sees a linear
range between min and max.
This is particularly useful to allow the full range of values for
throttle to be passed through to the joystick.
Adds a new RCTransmitter setting for the USB HID interface which
emulates a USB HID joystick. The scaled RC receiver channels
from any RCVR protocol are passed through to the various emulated
joystick controls.
The main use for this feature is to allow you to use your own RC
transmitter with any RC simulator on a PC.
This is known to work with CRRCsim but should work with any simulator
that supports joystick input.
It is now possible to have 1 to 6 flight mode switch positions
(usefull for guidance, position hold and similar use).
The input channel range is divided into N (1 to 6) zones and each
zone represents a flight mode. Default is 3 zones (backward compatible),
but more can be chosen.
How to use: configure Tx mixers in a way they provide required number
of different values for the same FlightMode channel. For instance,
using Turnigy 9X radio with ER9X firmware, one can create a mixer like
this:
-100 MAX ID0 Manual
R -50 MAX ID1 Stabilized1 (Rate)
R 0 MAX ID2 Stabilized2 (Attitude)
R 50 MAX RUD PositionHold
R 100 MAX ELE ReturnToBase
And set number of flight mode positions to 5. As a result, the 3-pos
switch (ID0, ID1, ID2) will provide first three flight modes, the rudder
D/R switch will override those and enable the 4th flight mode, and
elevator D/R switch will have highest precedence and activate the 5th
flight mode.
This will change the ManualControlSettings objectID.
There is a small issue that when it is in RTH failsafe mode and you regain
signal and your throttle is low you will disarm due to the timeout. That
means you'd suddenly get it back and plumet ouf of the sky. If you are
still holding throttle (which most people might do?) you will have control.
The timeout needs to probably start when you regain signal.
path functionality. These configurations that could result in
updatePathDesired or altitudeHoldDesired being called should result in an error
on startup to block arming.
1) Combining all binary or mode values into a single byte
2) Adding accessor functions to read/write the flag bits
3) Reduced the size of the time values from 32 bits to 16 bits
- both CC serial ports are now disabled by default (no telemetry);
- serial ports now have DSM2, DSMX (10bit) and DSMX (11bit) options;
- ReceiverGroups now have DSM (MainPort) and DSM (FlexiPort) options.
For DSM2 protocol there is an explicit resolution bit in the stream, so
the DSM2 should be selected. For DSMX there is no such bit, and user
should choose the resolution from the list configuring the spektrum port.
ReceiverGroups have single DSM option which is handled by the same driver.
Downside: this implementation saves received frame first, unrolls by the
end of frame. This should be ok, but may be improved by unrolling channels
on the fly in the rx callback.
Another minor difference is that a ChannelGroup is now bound to port:
DSM (MainPort) or DSM (FlexiPort). This was considered as acceptable
solution in order to not have 6 DSM options for each ChannelGroup and
even more in case of new DSM protocol variations.
Known problem: it is not possible to choose same protocols like
DSM2/DSM2 for two ports. It can be enabled by adding an exception to
common rule, though.
The DSMX throttle channel misbehavior (zero value) is not treated
specially yet. It should trigger the failsafe being out of bounds.
More info and data dumps are required to handle this properly.
