The curve editor allows you to define a name for the selected curve, the type, and of course set the coordinates.
When the cursor is on one of the editable coordinates, a LONG press of the ENTER key will bring up a menu
where you can choose a standard preset curve, mirror the curve vertically, or reset all points.
Global variables
Global variables are values that can be substituted to the usual number on every Weight, Offset, Differential or
Expo setting. Their main use is to group the adjustment of several parameters that should have the same value.
For example, aileron differential on a glider with 4 surfaces responding to the aileron function. When trying to find
the sweet spot for the differential value, instead of having to repeatedly edit the differential value in 4 mixers, all 4
can be set to use a global variable (e.g. GV1 resp. -GV1, selected by a LONG press of the ENTER key on the
Differential field). Then adjusting GV1 on this page is all it takes for all differentials to be updated.
Global variables are also flight mode specific, so instead of having to create separate mixer lines with different
values depending on the flight mode one can simply use a global variable with different values for each flight mode.
This can significantly help simplifying the mixer screen by avoiding many duplicate entries.
Global variables can also be adjusted in flight thanks to the Adjust GVx Custom Function that will be described
later, and help adjusting those parameters that are easier to tweak in flight like D/R ratios, expos or again
differential.
The Global variables screen allows setting a name for each of the 5 available variables for conveniency, and
seeing/setting the value each of them will have in each of the 9 flight modes.
Logical switches
These are logic switches that are used to compare values and combine various conditions.
The first "operation" column lists a few arithmetical, logical and differential operations. In arithmetical ones a and b
represent variables, x represents a constant. Variables can be every source, i.e. all those available in mixers, plus
the 5 global variables and all telemetry values. In logical operations the available sources are all physical and other
custom switches. Differential functions compare the variation of a variable since last match to another value.
