●
a~x: active when variable a is approximately equal to constant x (hysteresis added, as comparing a stick's
value for example would pretty much never trigger an exact match)
●
a<x, a>x: Active when variable a is smaller resp. greater than constant x
●
|a|<x, |a|>x: Active when the absolute value of variable ‘a’ is smaller than, or greater than constant ‘x’
●
a<b,a>b,a=b: See above, but with 2 variables
●
AND, OR, XOR: Logical and, or, exclusive or between 2 binary inputs
●
d>x, |d|>x: Active when the selected variable, respectively its absolute value has changed by more than x
since last time. For example, d>x Alt 10 would trigger once every time Altitude goes up by 10m. |d|>x Alt.
10 would trigger once every time Altitude goes up OR down by 10m.
●
TIM: A timer, TIM 0.5 2.0 would be active for 0.5s, inactive for 2s, and repeat.
Custom switches offer 3 more parameters: An extra AND condition (if selected, must be on for the custom switch to
become active), a Duration parameter (the minimum time a custom switch will be active for even if its conditions
become false instantly), and a delay parameter (that affects both activation and deactivation). See the title bar
header to see the function of the field the cursor is on.
A long press of the ENTER key on a custom switch's label will bring up a popup menu that allows you to
copy/paste/delete an entry for more convenient entry of similar settings.
Special Functions
This is the place where switches can be used to trigger special functions such as trainer mode, soundtrack
playback, speech output of variables etc.
The first column selects the trigger, which can be any switch (physical or custom) or ON (always on). A LONG
press of the ENTER key will switch to "toggle" mode (ending with t), i.e. the selected input will be turned on when
the selected switch is activated, and will remain on until it is deactivated and reactivated again.
Scrolling through the list you will also find a few more options: One (triggers just once when loading a model or
turning the radio on), SHdownS (short press of the momentary switch), SHdownL (long press of the momentary
switch).
The available functions are:
●
Safety CHx: When active, the output of CHx is forced to the selected value. A checkbox is there to enable
the function, which you would typically do after ensuring the value is set correctly and the switch is off if
your model is powered.
●
Trainer, TrainerXXX: Enables trainer mode globally, and for individual functions. Unless a custom function
is set for an individual function, turning the one set for Trainer automatically activates all 4 sticks.
●
Instant trim: When activating the selected switch the current stick positions will be added to their respective
trims. This is typically assigned to a momentary switch, and used on a maiden flight if you expect trims to
be way off. Instead of frantically clicking the trim tabs, you would hold the sticks so that the model flies
straight, and depress the switch once. It is best to remove that entry after the maiden flight, to avoid hitting
it by mistake and bringing the model badly out of trim again.
●
Play Sound: Play a simple tone from the available list.
●
Reset: Resets the selected item (Timer 1, Timer 2, telemetry values, or all of those)
●
Vario: Turns on variometer sounds (see
Telemetry setup
)
●
Play track: Plays a sound file from the SD card, with repeats at the specified interval
●
Play value: Speaks the current value of the selected parameter, with repeats at the specified interval
●
SD Logs: Logs the telemetry values to SD card at the specified interval
●
Volume: Adjusts sound volume using the selected source
●
Backlight: Turns backlight on
●
BgMusic, BgMusic || (pause): Plays a selected soundtrack from the SD card. The BgMusic Pause item
pauses the track when activated and resumes it once inactive again, while switching BgMusic off stops the
track completely.
