Pin 1: PPM/protocol in
Pin 2: No connect
Pin 3: Power
Pin 4: Ground
Pin 5: Telemetry data out

DJT module telemetry normally uses Pin 2 (in) and pin 5 (out) ?
Can the MultiModule be used as a DJT module (PPM protocol with TSSI) telemetry using both telemetry wires ?

See here for setting Gimbals stick directions: (viewtopic.php?f=95&t=9977&start=30#p128295).
Wiring with the M9 and Taranis Gimbals are the same.

Provided you flash the Multi module with the config set so one of the protocols selected by the rotary switch is FrSky 'D', then yes, the multi module should behave like a DJT module with the telemetry being sent at 9600 baud. However, the Multi module doesn't use the the second pin from the top, so the telemetry signal from the radio will not be seen by the module. However, this is not a problem as the only reason for that signal on a DJT is to be able to set telemetry alarms in the module, and the Multi module doesn't have any alarms to set.

My problem seems to be more hardware than software, specially when one of the gimballs works perfectly. Please in order to not to derrail this thread, answer me in the gimbals thread.

[bob195558]

Thank you Mike for explaining, of the Pin 2 Telemetry Wire which is only used for setting the Telemetry Alarms in the FrSky D-series modules.
I did not know this as I was guessing it was maybe for the TSSI signal.

Hi guys, some necroposting here. Finally I have my radio fully working and with all the mods done, the only thing left is I am still fighting with the multiprotocol module.

So, 9xtreme, with ersky9xProvR221g2 flashed
Multiprotocol module flashed following Mr Joao video tutorials.
Im triying to bind the stock flysky receivers, but I am not going too far...

In protocol I selected Internal, Multi, it is enabled, Protocol flysky, type flysky, RX num 0, autobind N, Option 0.

Then I do click in bind, but it does not bind. (of course I put the plug in the receiver)

Any clue?

Also, is there a place where I can download the latest software for the multiprotocol module?

Thanks!

[jhsa]

I have just bound an old flysky receiver to my 9xtreme radio with multi module installed internally.. No problems binding at all.
I remember some old Flysky receivers had the labels for Bind and Batt swapped.

Here is the link to the Multiprotocol Github page.

[Rad]

Uops, I wrote another post but vanished...

Anyway, I found the mistake, I had one wire conected wrong. Now everything works perfectly. Thank you very much.


This is how I fitted the module in the radio.

[jhsa]

Hmm, I would not place the antenna the way you did.
The active part of the antenna is surrounded by metal stuff like the switches, the gimbals, etc.
It will greatly reduce the range in my opinion. Specially in such high frequencies, antenna placement is very important.

Hi Rad,
You can mount your internal antenna on top where the old Flysky antenna was.

Bob B.

[Rad]

Damn, I thought it was Ok like that. I use the radio for tanks, so all the stuff will be maximum 20 meters away from me... Is there any way of locating the antenna inside? The way Bob sugests is the most logic way, but due to my sons use my RC stuff, I preffer to have the antenna inside. It is more safe...

I mean, this is not the first antenna they break...

[Rad]

what do you think about this?

[jhsa]

Much better..

João

[Rad]

Thanks mate. Then I will leave it like that.

[jhsa]

Testing is the best.. But I think it will be ok for ground models

After having everything working, I had to screw something again, lol.

I updated the bootloader (from 1.7 to 2.6)
And I tried to update the multiprotocol module with the radio.

I went to your link to download the latest version (1.2.0), but it seems there is no bootloader version.
https://github.com/pascallanger/DIY-Mul ... e/releases

So then I checked in the older version section (1.1.6) and I downloaded and flashed this:
Multiprotocol_V1.1.6_STM32.bin

But now the module does not work... So I guess I had to flash other thing.

Is there any place where I can download the file that I have to flash in the module? Or a tutorial for learning how to do it and stop annoying you?

Thanks!

[jhsa]

You don't annoy me at all.
when you say the module does not work, what does it do?
Check the link.

https://github.com/pascallanger/DIY-Mul ... -TX-Module

Scroll down, there is all the documentation.
Don't flash pre compiled files. They might not be the right ones for your radio / module.
You probably wiped out the bootloader, or flashed a file that has no "CHECK FOR BOOTLOADER" option enabled. I think this is disabled by default on the config file.

I just cant bind it anymore. Previously, when it worked, next to the word bind, something like (1.1.0.6) appeared but now is gone.

Definitelly I think I flashed the wrong file... I am at the work now so I wont be able to double check it until I am back at home, but I think I still can flash with the radio.

Anyway I think I will open the radio and I will follow your video tutorials again to flash everything again in the module with the FDTI.

I also took another look to the link you gave me, and even when I find files to download, I still cannot find the .hex or .bin for flashing it with the radio. Maybe is not there and I have to create it?

[jhsa]

It is always the best to compile it yourself. Then you make sure you have set all the options correctly.
If you have the 9xttreme board and the module is connected on the module bay (external), then you need to compile the module's firmware with "TELEMETRY INVERTED".
This could explain why the version number doesn't appear, and you can't bind.

You can also try to go to the "Model Setup / Telemetry menu, and enable "Invert COM 1".

If this doesn't work we will try to help compiling a new file when you come back.

I have no idea of how to compile it. Well, I did it some months ago following your videotutorial (the one where you were with one feet on the gravestone, lol) but I forgot almost everything, but I think is just a matter of following your steps again.

The module is internal, and according to a tutorial, I have selected COM 2.

Definitelly it seems I flashed the wrong firmware. From the downloads web I think I flashed one of them, dont remember wich one now, but probarblz the wrong one:
Multiprotocol_V1.1.6_STM32.bin

Multiprotocol_V1.1.6_STM32_INV.bin


Once I arrive home in some hours Ill try to flash the INV one, and if I cannot do it, then Ill reflash the module from the beginning following your video.

But anyway, it is an old version (1.1.6) I think it would be better to put the (1.2) but how do I do it with the 9xtreme?

[jhsa]

No, on COM 2 you want NOT INVERTED. make sure the "telemetry com port" in "Model Setup / Telemetry" is set to COM2.
Wait, I will compile it for you.. and attach to this post shortly. I downloaded a version a couple days ago.
See if you can flash it using the radio.

João

EDIT: Here it is the file. version 1.2.0.11. You will have to unzip it of course..

Hi Joao, It seems I cant flash it. It says "Failed" So i am going to follow your videotutorials and I will flash this new file you created for me (BIG THANKS)

[jhsa]

you might want to flash the bootloader first
This file was compiled with "CHECK FOR BOOTLOADER" enabled. So it will check for it. Don't know if it makes a difference.

João

[Rad]

EDIT: im working on it

[Rad]

Well, now Im frustrated... After failing flashing your compilation, I followed step by step your video tutorials but with no success. I have been able to flash the bootloader (I keep the old files when I flashed it), but when trying to flash your compilation, the radio says it FAILED

I did another compilation myself and same fate.

Any idea?

I attach a photo after flashing the bootloader. It is a screenshot of my computer, it shows my flash demonstrator and a screenshot from your video tutorial.

[jhsa]

Ok, what version of Ersky9x?
What COM port are you selecting when trying to flash the module from the radio?
You should select COM2.

João

[Rad]

ersky9xProvR221g2
I selected both ports with exact results.

I also tried with your compilation, with the new one that I did now, and with the old one I had from september...

[Rad]

Surprisingly after something like 40 atempts I managed to flash the module!!! I did the same again and again and again, but for some unknown reason it worked now.

I flashed it with your compilation, Joao. Now in the BIND area it says 1.2.0.11

As always thanks your your priceless help! Now I know how to update the internal module for future updates.

[jhsa]

Nice, that it is working..

Perhaps Mike has an idea why it took it about 40 attempts for the flashing to work.

I think you should learn how to configure the arduino IDE and compile the code yourself. Then you will know that it is always the way you want.
I don't mind compiling for you, but there is always place for more knowledge It is never too much
The information is on the documentation I have linked before

João

I have the same issue as Rad but after 40 times still no luck...

What I have done (I followed the youtube video from João to the letter...lol):
- I flashed my 9Xtreme bootloader and firmware with the latest 'ersky9xProvR221g2.zip' version
- Flashed 4in1 module with software from Midelic (https://github.com/midelic/DIY-Multiprotocol-TX-Module), just as in the youtube video from João
- I installed Arduino 1.8.5 (ZIP version) on my D-drive and opened 'Multiprotocol.ino'. Checked that the bootloader part is on. In de 'Board' selection I didn't have the STM32 boards. I googled and found a link to add the boards: https://onetransistor.blogspot.nl/2017/ ... o-ide.html. After this I had the right STM32 board: Board:"Generic STM32F103C series, STM32F103CB (20k RAM. 128k Flash), STM32duino bootloader. But when I compile the code I keep getting this eror:

collect2.exe: error: ld returned 1 exit status
exit status 1
(I also have the full error log but that's like 60 pages long...!!)

- So I took the 'Multiprotocol_STM32_1.2.0.11.zip' (just as Rad did) and tried to flash the module from the radio. But it keeps giving me 'FAILED'...

Am I doing something wrong? I really want to make it work!
All help is welcome.
