Yes, I bind using the bind option in the Protocol / Multi menu in Ersky9x. No need for the module's bind button. I also don't need the rotary switch or the USB connector as I flash the module using the radio. The LED was moved from the multi PCB to the back of the radio.. João Thanks for your answe...

I finally got some time to try it again to flash the module. What I did was I flashed the firmware direct to the module. I couldn't get the flashing from the tx to work. I bound the radio to my whoop and I'm a happy flying indoors..:-) I have another question: I know that you ,João, use the module a...

Hay Mike, I have set it to 'Flash from tx'. I followed the steps again, to see what I could have missed but I think I did everyting right. Still the same error on the tx. After that I selected the option 'Upload via serial', so I uploaded the firmware via the FTDI adapter to the module. So the modul...

The bootloader is a different piece of firmware. Go here: https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/docs/Compiling_STM32.md#preparing-to-upload-the-firmware , then follow the instruction for "Burn the bootloader". Mike Thanks Mike! Somehow I skipped that step...

What bootloader did you flash to the module? The STMduino bootloader is for flashing from the USB, not the radio. In the Arduino IDE, have you used the "boards manager" and installed "Multi 4-in-1 STM32 Board"? Hay Mike, I'm a bit confused. Is it correct if I say that I first ha...

Well, I tried to flash the module from my tx but I only get the message 'Failed'...[emoji849] When I was flashing the bootloader to the module via the FTDI adaptor, the FTDI voltage was set to 5V. Is it possible I fried the module? When the module is in my tx and I turn the tx on, the red light on t...

Thanks Rad! I will check everything twice...[emoji3] You are helping a lot this way! I hope In can get to it this weekend.

collect2.exe: error: ld returned 1 exit status exit status 1 I had the same problem that occurred by simply adding or removing a line of code or even a comment. There obviously is a well known, but never resolved problem in the linker in, at least, arduino 1.8.0 . You may try the following (it did ...

That version I used on the video is very old already.. You should flash the latest version. About setting the arduino IDE and compiling and flashing the multiprotocol code, please follow the link and read the documentation. Things changed a bit :) https://github.com/pascallanger/DIY-Multiprotocol-T...

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 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 lett...

It shows that theory and real life sometimes not the same!
Good thing you have tested this thoroughly!!

I like the two Mosfet solution

Is this board ready to make? Or do you still want to test something on the two-Mosfet board?

Maarten

Nice demonstration João!

Can't wait untill you had the time to test this with the charging port b/c after that I would very much like to make the PCB you made and put it in my radio..

Maarten

Incredible how fast you made this!! (you just never sleep, right?!)

Looks nice and I hope you will not frie the 9x board...! I have my fingers crossed...

I assume you have a 9X board to test it on? Otherwise I can also test it of cource.

Maarten

You have don a lot of work again João! It keeps better and better..

I will have a look for a program, the one I used in the past, to see if it is still free to use.

I have a question: is the 6 pin connector missing from the PCB? Or do you have a other way of connecting the board to the radio?

Wow João! The speed you come up with designs is amazing...

The number of parts is indeed kept as low possible. Nice!

You will test this on the breadboard, but do you also test circuits with a computer program?

Single sided PCB would be nice...

Are the circuits in the red and green rectangles as the original circuits in the radio (exept for the green LED with resistor in the green rectangle)? Will breadboard this a bit later as my wife is getting in my nerves now.. She needs my computer.. GGGRRRRR v :twisted: :mrgreen: You have to keep you...

Super that it connects to the 6 pin connector! Right, I understand the ON/OFF switching of the radio and charging circuit. I think I have an idea of what to do, I think i will go back to one of my original ideas for the charging circuit, and it will use the original positive switching but controlled...

The board that you and andrewju have designed (in more then one version), is it connected via the original 6 pin connector from the orignal switch board? Let me put it like this: Is this new board a drop-in replacement for the original switch board? Ok, a little update. My previous design that I hav...

Let me check. It's been a while.. João Of course! Take your time... :D Thanks for looking into it agian! You also andrewju!! Let me check if I still have my Eagle files for this project (it may take me a couple of days)... I should certainly have some unpopulated PCBs of it, for sure! That is a rea...

Which radio do you have? I have a Turnigy 9X with a 9Xtreme smartieparts board and (since a few days) with the M9 gimbals in it. If you want to build one we can revive this project :) I really want to build one because I want to have more safety build in the radio.. :) Do you have the circuit with ...

Hello João,

I'm wondering how this project is going. Have you been able to test this project lately?
I sure would like to help with the testing if that is what still needs to be done.

This redesign of the switch board is a important mod I thinks!

Best regards,
Maarten

Thanks all of you for the reply's! I reversed my sticks, now it's all ok.

I love the feel of the M9's and the precision! Nice mod...

P.S. I reversed the sticks on the radio (not via eepskye)

Thanks Bob!! I will look into it this weekend...

I got my M9's in. It went super easy because of your post Andrewju!! I cut off less meterial of the alu plate: https://2.bp.blogspot.com/-_j05Gd2_mqA/WRYZEg1G_8I/AAAAAAAADTI/sWUFLk2UMoUqdFzif4hoGjOuHq5dRiUJACKgB/s640/IMG_20170512_201634.jpg I soldered my gimbals instead of using connectors.. :) But ...

I also got a couple of M9 gimbals for my 9Xtreme (after 9 weeks of waiting for HorusRC to have stock again).

Thanks for the posts andrewju!! This will make the mod go so much easier! Knowing where to look for and what I can expect.

When I got them in I will report if aything when different.
