4.4.4. Mix control (Mixer)

Mixing page for channel settings

The mix control page allows you to combine as many input sources as you want and map them to any one or more of the 32 output channels. Finally use the next page (Outputs) to make these purely logical outputs to fit the model device

You have complete flexibility in controlling the mixing from any input to any output channel.

A mix puts one input into one channel. The inputs are configured in the Inputs page, which defines any input type.

The mixing control page can also use other channels as the source of the current channel, and output from the current channel after re-mixing. It can also mix one or more channels to another or multiple channel outputs, which can combine very powerful complex functions.

All inputs range from -100% to + 100%. Gimbals, knobs, sliders, channels, global variables, and coach input.

If you want the servo of the No. 2 plug connected to the receiver to be controlled by lifting (ELE), you only need to create a mixing entry on CH2 and use the Ele input as the source of operation.

Each channel can have many lines, and you can choose the operation between each line. Long press the ENT key and select Insert Before / After to create a new line.

By default, all lines on the same channel are added together, and the next line can choose to be superimposed or multiplied with the channel value of the previous line, and replaced completely.

Please note that the currently active row of settings will be displayed in a bold font, making it easy to recognize the item currently in use at a glance. The CH1 channel shown in the figure is input by the Ail gimbal, and the three states of the SA switch are used to switch three-stroke amounts.

To edit a mixing control, use the scroll wheel to select the mixing control item up and down, and press and hold the ENT key to enter the editing submenu. Select Edit and press the ENT key momentarily.

The combination of these operations allows the creation of complex mathematical operations and is often considered one of the biggest benefits of using OpenTX.

Delay Up/Dn: The response of the output can be delayed as the input changes. (In seconds).

Slow Up/Dn: Regarding input changes, the response of the output can be slowed. For example, slow speed can be used to slow down retraction driven by a normal proportional servo. The output will cover the time in seconds from 100 to + 100%.

4.4.5.    Outputs

Total output page, final channel output overall settings

4.4.6 Curves

The curve can be used to modify the control response in the Inputs, Mixes, or Outputs page. Standard curves containing Expo and Differential can be used directly in these sections. This page is used to customize any kind of curve.

Can set up to 32 curves

The curve can be between 2 and 17 points and can have a fixed or user-definable x coordinate.

X value represents input, such as the course of the gimbal from low to high

Y value represents output, such as the process of channel output from low to high

Name:Name the curve, easy to find when recalling the curve in other settings

Type:Curve type

StandardStandard type, only Y point (output) can be edited, ranging from -100 to 100
CustomCustom types, both X (input) and Y (output) points are editable, ranging from -100 to 100

Count: The number of points on the curve, between 2 and 17.

Smooth: If checked, create a smooth curve through all points.

When customizing, move the cursor to X and Y coordinates, and change the position of each coordinate point according to your needs.

Depending on the type selected above, this allows writing the X coordinate of a standard curve, or the X and Y coordinates of a custom curve.

Long press the ENT key on the coordinate point to enter the submenu:

Preset: Select presets with slopes of -45 °, -33 °, -22 °, -11 °, 0 °, 11 °, 22 °, 33 °, 45 °. When defining more complex curves, choose reasonable presets will reduce some steps.

Mirror:Mirror the curve vertically.

Clear:Clear the current curve.

4.4.7.   Global variables

Global variables are customizable values that can be used as temporary values for custom operations. In complex functions, the values of global variables are automatically modified through certain trigger conditions for conditional judgment or any other purpose. Global Variables can be used as input or output real-time adjustment parameters, and can also be used as parameters in flight mode and curve definition. Global variables can be used in any place where numerical values can be entered to achieve some automated control.

They are also specific flight modes, which avoids having to use separate mixing lines with different values for each flight mode. This greatly simplifies mixing pages  and makes them easier to understand.

By using the “Adjust GVx” option in the Special Functions page, you can even adjust global variables on the fly, so you can quickly optimize settings such as double- rate ratio, exposure, differential, flap to elevator conversion, and more. If pop-ups are enabled (indicated by! Next to the GV label), when the variable is updated, a pop-up window with the variable name and new value will be displayed on the main view.

“Global” means that global variables can be used to set pages for the entire model, but not for all models. Each model has its own set of global variables.

There are 9 global variables available.

Modify the value directly or press and hold the ENT key to pop up the sub-menu to change the type and parameter of the global variable.

Name: Setting name

Unit: Units, switchable between normal and%

Precision: Precision, which can be used in decimal mode. You can set this mode corresponding to the percentage.

Min: Minimum value, which can be limited when the value is changed dynamically

Max: Maximum value, which can be limited when using dynamic change values

FM0-FM8: You can specify a value for each flight mode or set it to be the same as the other flight modes. Press and hold the ENT key to switch the input value and select the flight mode in this field. When editing a value, it will increment / decrement by 1 or 0.1, depending on the “Precision” setting above.

4.4.8.   Logic switches

The logic switch is a user-programmed virtual switch. Like the physical switch, the logic switch is also a switch, but unlike the visible switch, which can be moved by hand, the logic switch is an internal switch triggered by some conditions. The judgment condition you set allows the remote control to automatically turn on or off the logic switch to achieve a certain or a series of automated actions.

The setting of the L01 example in the figure is expressed as follows: When the return value A1 is less than 11.0V, the L01 switch is automatically turned on. In the settings of other pages, L01 has the same function as the physical switch. You can define the corresponding function for L01 on or off. In this way, a switch is automatically executed according to the parameters that change in real time.

The remote control system provides 64 logic switches, each of which has three judgment methods:

  1. Compare the values of parameters a and b, a corresponds to V1, b corresponds to V2, a and b can be any source, such as input source, channel, switch, or return item, etc.
  • Compare the value of parameter a and data x, a corresponds to v1, x corresponds to v2, and x is a fixed value, which is used to compare with parameter a
    • Parameter a can be compared with its own calculation result. For example, the change of parameter a itself can affect the current state of the logic switch.

Functions

 a=xTriggered when the parameter v1 is equal to the data v2. For example, if the thr gimbal is less than -90, the current logic switch is turned on when the thr gimbal is less than -90%.
a~xTriggered when the parameter v1 is approximately equal to the data v2, approximately equal to the range of about 10%
a>xTriggered when parameter v1 is greater than data v2
a<xTriggered when parameter v1 is less than data v2
 |a|>xTriggered when the absolute value of parameter v1 is greater than v2, the absolute value is that it will become positive no matter whether it  is  positive or negative
|a|<xTriggered when the absolute value of parameter v1 is less than v2
 ANDAND operation is triggered when both parameters v1 and v2 meet the conditions. For example, v1 is the switch SA ↑ and v2 is SB ↑ , which  indicates that the current logic switch can be turned on when both SA and SB switches are in the ↑ position.
OROR operation,  which can be triggered when one of the parameters v1 and  v2 meets the conditions, or when all the conditions are met
 XORExclusive OR operation, triggered when one of the parameters v1 and v2 meets the conditions, not triggered when all the conditions are met or all  the conditions are not met
      EdgeIs a momentary switch (very short duration, about 30 ms), it will be triggered when V1 meets the conditions V1: Can be physical switch, logic switch, trim button V2: It is divided into two parts [t1: t2], t1 is the minimum value, and t2 is    the maximum duration of V1. The logic switch is triggered only  after  t1 when V1 meets the conditions, and is closed before t2. If t2 is left as “—” then only t1 is applicable. When V1 changes  from on to  off (ie falling edge), the logic switch will be triggered, and then the logic switch will be turned on for 1 processing cycle (about 30 ms). If t2 is set to “<<“, the logic switch (ie,  rising edge)  is triggered when V1  changes from  off to on.
 a=bTriggered when the parameter v1 is equal to the parameter v2.  For  example, when the value of the thr gimbal and the value of the ail gimbal  are equal, the type of v2 at this time is not digital data, but a source
a>bTriggered when parameter v1 is greater than parameter v2
a<bTriggered when parameter v1 is less than parameter v2
△≥x△  is  the  mathematical  symbol  Delta  (difference  value).  It  is triggered when  the difference of the  parameter v1 itself  is greater than  or  equal
 to the value of data v2. Switch, this item only judges the  difference when v1 changes from small to large
 |△|≥xTriggered when the absolute value of the difference of the parameter v1 itself is greater than or equal to the value of v2. This  judges  the absolute value. Since the negative value also becomes positive, a  change from v1 to v or from v1 to trigger the current logic switch
 TimerThe switch that automatically loops all the time. V1 is the on time and  v2 is the off time. It can be defined by v1 and  v2 to automatically cycle  at constant intervals.
Stickyv1 can only switch on, v2 can only switch off

AND Switch: With the arithmetic switch, this item can set any physical switch and logic switch. The current logic switch can be triggered when the switch set by this item and the current item meet the conditions

Duration: Hold time, the length of the current logic switch after it is triggered. If there is no parameter, the default is always on. If this item is set for time (0.1-25 seconds), the current logic switch will automatically turn off after this time.

Delay: Delay, after the trigger is turned on, the range is 0.0 to 25 seconds.

4.4.9.   Special Functions

The combination of logic switches, special functions, global variables, and passback items opens up a variety of exciting new features for the RadioMaster TX16S. E.g:

-Changes in battery voltage data returned by the receiver can trigger voice alerts

-Altitude data returned from the barometer on the aircraft, real-time broadcast of the aircraft’s altitude

-By defining voice for the switch, real-time voice broadcast operation on the remote control

-Use logic switches and global variables to let the remote control perform a single or a series of automated actions

-Call lua scripts with switches or logic switches for more advanced custom functions

-Use the knob to adjust the volume

-Use the switch to adjust the backlight brightness

In addition to a few of the commonly used methods listed above, the ever-changing features allow you to realize your imagination

The three examples in the picture are represented as:

SF1:When the SF switch position is ↑, the CH3 channel will be covered by -100. Usually this setting is used to lock the throttle.

SF2:When the logic switch L01 is automatically turned on, lowbat (low battery voltage) voice will be broadcasted. The rightmost 3s means that the voice will be broadcasted every 3 seconds. Automatically turn on when

SF3:When the remote control is activated, the LS slider is defined as a function to control the system volume

Each model can have 64 special functions. In addition, there are 64 global settings that are common to all models. To use the global function, please enter the Global Functions page in the remote control system settings to set it.

Each setting is activated with a trigger switch. You can select physical switches, logical switches, fine-tuning buttons, and flight mode. There are two other special options, ON and Ones (which are always enabled when the machine is turned on), and One (which is performed only once when the machine is turned on)

Press and hold the ENT key to enter the sub-menu for displaying sources by category. Scroll up or down to select the desired category and press the ENT key.

The following functions are triggered by the switch selected above

OverrideOverride channel value
TrainerCoach mode enable switch, it is recommended to set to SH rebound switch, this switch is used to activate or stop the operation of the student machine
Inst.TrimOne-touch saves the current gimbal position as a fine-tuning value
ResetReset, you can choose to reset all or reset one way individually. The content of the reset option is the same as that in the main interface.
Set TimeUsed to set the timer, set the timer time and turn on when the switch is turned on
        AdjustAdjust the global variable Gvar and enter a fixed number directly Press and hold the ent pop-up menu to change the way to set Gvar. There are three options: Mixer Source: Set the value of Gvar with an input source Global var, another global variable Inc / Decrement: increase or decrease
VolumeSelect a knob or slider to adjust the volume
SetFailsfeUse the switch to set the receiver’s runaway protection anytime, anywhere
  Play SoundPlay a sound ! 1x: Play sound once, not at startup
 1x: Play sound once. 1s-60s: broadcast at intervals (seconds)
Play TrackPlay wav file in SD card, single broadcast and loop broadcast are the same as above
Play ValueVoice broadcast value, can broadcast values from any source, such as real-time values such as gimbal, voltage, altitude, time, etc.
Lua Script:Call the specified script, and the script file should be placed in the / SCRIPTS / FUNCTIONS / folder of the SD card.
BgMusicBackground music, loop play wav files, take effect immediately after power on
BgMusic IIPause background music
VarioBroadcast Vario value
Hapticshock
SD LogsStart recording logs, save on SD card, can set time interval 0.2-25.5 seconds
  BacklightTo control the brightness of the backlight, you must first define the backlight ON and OFF brightness in the system settings. This uses  the switch to switch the corresponding ON and OFF brightness of the backlight.

4.4.10.   Custom Scripts

Custom script allows you to customize the functions of the remote control. The scripting language used is Lua, which is a lightweight embeddable scripting language. You need to implement custom functions in the remote control. There are three basic types:

One-time: The script runs only once and then terminates. Initialization of some parameters, and a wizard for creating a new model. The script is stored in the SCRIPTS folder of the SD card.

Mix: A script that executes in a loop, similar to the main program, and is always executed during remote operation.

Function: The script is called in Special Functions. This script is only allowed to execute when the switch in the special function is turned on, and closed when the switch is turned off.

There are some caveats-if the script stops executing, you should never use Lua model scripts to control any aspect of the model that might cause a crash. The reason is that if the script tries to use too much CPU time or memory, it will be closed and it will not run again when the model is selected.

The Custom Scripts page is for mixed-type scripts that run continuously. These scripts should be placed in the / SCRIPTS / MIXE/folder of the SD card.

There can be up to 9 custom scripts.

For script development and documentation, please refer to the OpenTX 2.3 Lua Reference Guide:

4.4.11.   Digital Transmission and Telemetry

Each value received via digital transmission is considered a separate sensor with its own properties. Multiple identical sensor types can be connected, but the physical ID must be changed. For example, a sensor for each battery in a 2-6S lithium battery,  or monitoring individual motor currents in a multi-motor model. Each sensor can be reset individually with special functions.

Receiver Signal Strength Indicator (RSSI): The value transmitted by the receiver in the model to the remote control, indicating the strength of the received signal. The warning can be set to warn when it is below the minimum, indicating that you are in danger beyond the flight range. Factors affecting signal quality include external interference, long distances, poor steering or antenna damage, etc.

It is not an absolute measurement, but a number that represents the ratio of the signal to some initial “good” value. The number is relative, but can indicate that the model may be close to the range limit of the controlling aircraft.

When the return signal is completely lost, the remote control will prompt “Lost return signal”. Please note that due to a failure of the return link, the remote control can no longer warn you of RSSI or any other alarm conditions, so no further alarm sounds.

Digital settings:

5.  External UART

The TX16s has two externally accessible 5v UART ports that are direct output non- inverted TTL. Aux 1 is a 4 pin TTL UART, Aux 2 is a 5 pin TTL UART with a  CTR connection directly to the Radios MCU.

IMPORTANT NOTE!

Ensure the correct polarity and voltage are applied when connecting to UART interface. Do not apply more than 5v to the UART port at any time.

External UARTS can be used for additional hardware and projects such as:

  • Adding a Bluetooth module.
  • Updating compatible receivers
  • External Telemetry Data
  • Antenna Tracking
  • And more!
