Introduction (v0.56 Black & White Small Radios)

!!!!!NEW!!!!!!: Finally was able to create the Plane Setup for Smaller Radios There is still significant memory limitations in some of this radios, so the Setup and FP was split in two files. The file 'DSM FwdPrg_56_STUP.lua' is the new one to create the planes setup that works together with 'DSM FwdPrg_56_MIN.lua'

How to Use it

Step #1: Make sure that the /MODELS/DSMDATA folder exist.

Step #2: Run the "DSM FwdPrg_56_STUP" first to setup the plane wing, tail and channels to use for each surface. At the end it will ask you to "save" the configuration. That saves a file in the /MODELS/DSMDATA folder.

Why the RX needs to know the Plane Setup?? The AS3X/Gyro and SAFE needs to know what surfaces to move to do the proper correction in flight. It needs to know what channels are you using for ailerons, elevarors and rudders (could be 1 or 2 of each). Also if you have special Wing like a delta wing, the elevator and aileron functions are on the same channels.. same with V-Trails, Ruder/Elevator are combined. All this information is shared with the RX during "First Time Setup" as well as "Relearn Servo Setting". Older version of 0.55 MIN hardcoded this info to be a plain 4-ch regular plane, thats why we discourage to use those function.

Step #3: Run the "DSM FwdPrg_56_MIN". It uses the model configuration created in step #2 to properly tell the receiver the plane configuration for initial setup. If you get "Cannot load model config", that means that the file was not created on step #2. Once it shows the intial forward programming page for your receiver, usuall "Gyro Settings and Other Settings". You can properly setup the a plane from initial setup... if you are not familiar with this step, view some of the videos. There are already multiple videos showing how to do it EdgeTX color version, or the Spektrum official videos, the menus are the same.

Dealing with Low memory

On my FrSky QX7 (Probably the one with the lower memory compared to Radiomaster Boxter and maybe Zorro), it will give you "not enouth memory" the very first time you try to run it since is compiling + running. Try to run them at least 2 times again, this times wll just run (not compile). In some ocations that keeps giving memory problems, i have to restart the radio, and try to run it right after restart.

After it runs fine, and you try to run it the 2nd time and gives "not enouth memory", you have restart the radio.. for me this is random.. sometimes i can run it many times consecutively.. but once it gives memory error, have to restart to be able to run again. Once it starts, it should work find after... is the statup who loads what it needs to memory.

I am running EdgeTX 2.9.2 (there was some memory cleanup in 2.9.0, and 2.9.1 to get a bit more memory) I left version 0.55 in the files, since it uses less memory, it can change the mayority of FP parameters, but cannot setup plane or Relearn Servo Settings (don't execute the menus who say 'DON'T USE!!').. v0.55 and v0.56 MINs can co-exist.

Deployment

Uncompress the Zip file (ZIP version) into your local computer. In another window, open your TX SDCard and go to /SCRIPTS/TOOLS.

When upgrading from a previous version of this tool, delete your /SCRIPTS/TOOLS/DSMLIB before copying the new one (if you customized the menu messages, inside DSMLIB do a backup of the message files first)

1. The zip file has the same structure as your SDCard. If you want to copy all the content of the zip file into your SDCard, it will create all the directories and files in the right place.

For the MINimalistic version, Your TX SDCard should looks like this:

/SCRIPTS/TOOLS
    DSM FwdPrg_56_MIN.lua     -- Minimalistic version for radios with LOW memory (Can setup planes)
    DSM FwdPrg_56_STUP.lua    -- `NEW!` Setup plane for minimalistic version (LOW Memory radios)
    DSM FwdPrg_55_MIN.lua     -- Uses less memory than v56, but cannot do initial setup of the plane

/SCRIPTS/TOOLS/DSMLIB/       -- (ALL CAPITALS) Libraries ane extra files
    DsmFwPrgMIN_P1.lua            -- Part1 of extra files for Min
    DsmFwPrgMIN_P2.lua            -- Part2 of extra files for Min
    msg_fwdp_en.txt               -- Menu messages in English  (common for all radios)
    MIN_msg_fwdp_en.txt           -- Menu messages in English  (overrides for 128x164 resolution)

Other Directories/Files

/LOGS/dsm_log.txt		       	--Readable log of the last RX/TX session, usefull for debugging problems

NOTE for FC6250HX FC+RX version

For the full size FC6250HX, Only use V0.55 or newer.

DO NOT use previous versions to do the Setup -> Gyro Settings -> Orientation. The problem was that it did not have the orientation messages.. and you are were choosing blind. The calibration will never stop until you place the RX in the right orientation, even after restarting the RX (if flashing red, is not in the right orientation.. if flashshing white is in the right orientation). If you run into this problem, and lights are blinking red, rotate the FC on the longer axis until you get white blinking.. keep it stable, will blink white faster andlet calibration finishes.. after that is back to normal.

OpenTX: When you enter "forward programming" you will hear "Telemetry lost" and "Telemetry recovered".. The FC led will blink white, but when exit FP, will blink red...is not problem.. but will need to be power cycled to get blinking green again.. i think is something related to temporarilly loosing the connection with the radio..researching the OpenTX code since it only happens with this helis FC.

Common Questions

1. RX not accepting channels higher than Ch6 for Flight-mode o Gains:

   • All Spektrum RX are 20 channels internally, even if it only has 6 external Ch/Ports to connect servos.

   • Make sure that when you bind your RX, you select the proper range of channels to use.. By default, ch1-ch8.

   • You have to mapped a Switch/Slider to the channel, togling/moving will select the channel on the menu field.

   • The RX validates the channels, and it does not detect signal on a channel, it will not allow to select it..that is why is important to move the switch/slider, so that the RX knows that is a valid channel.

Changes and fixes

v0.56:

1. Fix Tail-Type "Taileron" functionality that was not working. Also validated V-Tail and Delta wings.
2. Added Taileron and two Rudder config (Many Freewing Jets like F18,F16, etc)
3. Gyro-Reverse Screen now shows what is the channel/port used for (Ail, Ele, Rud, etc)
4. COLOR ONLY: Gyro-Reverse Screen now shows what information that shared with the RX about each channel (Role, Slave, Reverse).
5. NEW!! Initial version of Plane Setup for B&W radios

V0.55:

1. Finally found where the TX reports to the RX how many channels is transmiting. The TX now reports itself as a 12ch radio instead of 6h. (DSM Multi-Module limit). This fixes a few things:

   a. Many places where you have to select channels > CH6 for Flight-Mode, Gains, Panic now works properly with the scroller. The radio is still validating that you are not selecting an invalid channel. For example, if you have an additional AIL on CH6, it will not allow you to use CH6 for FM or Gains.. it just move to the next valid one.

   b. When setting up AIL/ELE on channels greater than CH6, on previous versions SAFE/AS3X was not moving them.. now they work up correctly. Set them up in the first in CH1-CH10. Why CH10?? Thats what fits on the reverse screen, otherwise, have to add more screens.

   c. Some individual Gain channels was not allowing to setup on CH greater than CH6. Now is fixed.

2. User Interface: a. RTN Key now works as Back when the screen has a Back. Makes it easy for navigation.. Presing RTN on the main screen exists the tool. b. Much faster refresh of the menus. Optimize the process of send/recive menu data from the RX.

3. Support for FC6250HX (the one with separate RX).. Setup Swashplate type, RX orientation works properly.. This are menu options that the smaller version that comes in the Blade 230S did not have.

V0.54 Beta:

• First version for the small screens, and limited memory. Only can change existing values, it cannot setup a brand new plane or new RX from Zero
• Fix problem on editing the SAFE Mode Attitude Trim
• First version with externalize merges, so that it can be translated to other languages

Tested Radios and RXs

• Radio: FrSky QX7: Due to limited memory, could be that the first time is does not start (not enouth memory to compile+run), but try again after a fresh TX restart.

• AR631/AR637xx

• FC6250HX (Blade 230S V2 Helicopter)

• FC6250HX (Separate RX.. use only V55 or newer of this tool)

• AR636 (Blade 230S V1 Heli firmware 4.40)

Please report if you have tested it with other receivers to allow us to update the documentation. Code should work up to 10 channels for the main surfaces (Ail/Ele/etc). All Spektrum RX are internally 20 channels, so you can use Ch7 for Flight Mode even if your RX is only 6 channels (See common Questions)

Messages Displayed in the GUI

If in a screen you get text that looks like Unknown_XX (ex: Unknown_D3), that message has not been setup in the script in english. If you can determine what the proper message is, you can send us a message to be added to the library. The XX represents a Hex Number (0..9,A..F) message ID.

If you want to fix it in your local copy, all messages are in the file SCRIPT\TOOS\DSMLIB\msg_fwdp_en.txt. (english version)

Example::

T |0x0080|Orientation
T |0x0082|Heading
T |0x0085|Frame Rate
T |0x0086|System Setup
T |0x0087|F-Mode Setup
T |0x0088|Enabled F-Modes
T |0x0089|Gain Channel
T |0x008A|Gain Sensitivity/r  -- Right Align
T |0x008B|Panic
T |0x008E|Panic Delay

For example, if you get Unknown_9D in the GUI and your now that it should say NEW Text, you can edit the lua script to look like this: T |0x009D|NEW Text -- NEW Text added for AR98xx

Local Language Support

Some settings that can change (top of Lua file): local LANGUAGE = "en"

If you want to translate the menu messages to another language (like french), copy the file msg_fwdp_en.txt into msg_fwdp_fr.txt, translate it, and change the language in the lua file to "fr".

LOG File

The log file of the last use of the script is located at /LOGS/dsm_log.txt. It is overridden on every start to avoid filling up the SD card. So if you want to keep it, copy or rename it before starting the script again. (it can be renamed in the TX by browsing the SD card)

The log is human readable, and can help use debug problems remotrly

Validation of data by the RX

When you change a value in the GUI, the RX validates that the value is valid. This applies to channels as well as values.

Version 0.54

First version for Small Radios

Known Problems:

• Currently cannot setup a plane from scratch.. (Working on it).
• The first time you run it, it will give you "not enouth memory", but should work the 2nd time after the first compilation (creation of .luac). After that, it should start right away.

Version 0.2
