which is MJX use protocol ?

Thanks Dureté and Hexfet for everything, I got to try on the moontop, 3015-1/2 and Bayangtoys. Works great!

Yeah everything is fine, was just 1/10th sec, was talking knowing throttle was at zero, disengaged TH without even looking at the hex, thinking it needed some kind of arm sequence, then jumped on TH again, helos reflexes kicked in very fast. My fault anyway, if it wasn't a "toy" I would have been more cautious. Thx again for the files, and your work on this, it's greatly appreciated

Anyone else have any issues on the X600 with the model file from a few posts back where the hex immediately yaws pretty harshly to the left on takeoff and constantly? It didn't behave that way with the stock control. Tried to trim but it unless the buttons are different trim buttons on the 7e didnt seem to work? Thanks!

Not sure what's your problem, I have tested my X600 model file (are you talking of my X600 model file? ) and is working fine on the emulator
And as I wrote before, it's a copy from my X800 model file fully tested.

Ok, new build to test
I managed to disable driven trims when Headless mode is enabled (Channel 9 > 0 ). I thought the driven trims are causing to work erratic the Headless mode, but is only my guessing , needs to be tested with an X600 or any other MJX Quadcopter with Headless mode.
I tested on the emulator and seems to be working.

I saw that the camera for the x800 needed to be tested so i took my camera from my old t43 and mounted it on my x800.
It works great.
Thank you.

Great!
Thanks for testing

Test report:
FW: Durete's version : 337f038
WLH-08 : All functions works fine, I don't have camera with it.
JJRC H13C :(WLH08 option) All functions works fine, I don't have camera with it.
MJX X600 : with Durete's ini file all functions works fine , except headless mode, same as I mentioned before , when I turned X600 head to myself(6 o'clock orientation),X600 moved very very slow,but in other orientation it works fine , I don't have camera with it.

Thank Durete for your great job!

Edit : New FW e9e4b2c not tested yet.

Thanks for testing.
Yes, I saw the weird Headless mode with my buddy's X300C. Switching off Devo, and binding again the stock transmitter headless mode is working fine as should be.
That's because I'm guessing the FC is going crazy with driven trims when headless is enabled.
Please, test last version. With that version, when you enable Headless, the driven trims are disabled, sending only center value (0x40), so also you will feel the rates (roll and pitch) are reduced.

Perfect! e9e4b2c FW is ok for headless function! Thank you Durete!

Hi everybody,
Finally I have modded my Devo 7E.
I own a MJX X600 last revision with big landing legs and MJC C4008 FPV Cam.
Installed Durete FW (not the last one with headless fix) and X600 files.
Bind ok.
When I throttle up the X600 go up, but i will slowly spin over itself on left side.
I tried to set trim but with no luck.....
Please, how I have to set TX control like stock control? than I can test even with camera.
P.S. I don't know why, but I am not able to control C4008 FPV cam by TX: If i push upper right button (intermediate mode setted) the X600 flip, but no take video nor photo.
Thank you again for your work

Thanks for testing . Did you test the light control with your X600? I remember your X600 doesn't turn off the led lights. Perhaps is something related with your TX and not with your X600's FC. I know now is working because I tested with my buddy's X300C.
So now, is confirmed everything is working fine. Anyway, we need yet to reverse the led channel behaviour (I didn't because I don't know how to do it ) and the most important thing .... figure out the relation between TX IDs and RF channels. This 2 things are above my programming skills and we will need any real programmer, not me, a hardware man
If I'm not wrong we have 3 different TXs bind captures so far. X600 from DC59, X800 from me and X300C from my buddy.
Bind captures from different TXs are welcome to figure out this relation. I will add at least 2 or 3 more bind captures from different TXs as soon as possible.

Hexfet has this code, and he updated yesterday his MJX protocol code with my modifications amending my programming errors
I will update his new code disabling the driven trims when Headless is enabled ( and probably he will need to amend the code again )
Almost there!

Hi, did you Calibrate your Devo sticks after DeviationTX install ? (Transmitter menu from Devo)
If I'm not wrong the FPV camera can't be controlled with Devo nor stock TX. This camera is transmitting continuously as soon you connect battery at your quadcopter. At least with my buddy's X300C here's how it works.
The right shoulder button at stock TX is sharing the Video/Flip function (Channel 11 at this protocol implementation). When any MJX camera with MicroSd card is installed, the right shoulder button works as Video function, and the Quadcopter doesn't flip.

Bad news for myself, CH5 light control didn't work for my old X600, I bought a new high landing gear few days ago and I found it can't be installed on my v1 X600 … that's too bad, it's really different from v1 and v2 X600.

HI Durete,
thank you for your reply.
First: I am able to switch on/off led of my X600 with shoulder left button
The MJX C4008 FPV camera is with MicroSD card installed, but if I push shoulder right button no video or photo is taken but, only flipping.
I had to try if it is flight mode related ....
Sorry for silly question: how to calibrate devo?

It is possible to reset DEVO to original (not stock) setting)?

So probably the first X600 is pretty similar to the X400 V2 (with headless but without light control)

The option is under "Transmitter menu". Sorry, I can't explain better now, I'm out of home and difficult to explain with the cell

@Lukappaseidue:
Go to transmitter menu then Transmitter config. The second option is stick calibration.
The transmitter settings are stored in the tx.ini. if you want to save your settings then save this file. If you want to go back to the original settings, then copy the original tx.ini file to your transmitter.

Hi tom, thank you for your help.
I have found the menù you said, but with no luck... I have calibrated stick and knobs, but now x600 fly fast to the left

please, could some one share its tx.ini file
The one I have, is from the last nightly devo:
this is what inside:
current_model=1
mode=2

[calibrate1]
;Aileron (Mode 1)
max=3813
min=530
zero=2171
[calibrate2]
;Elevator (Mode 1)
max=3549
min=354
zero=1951
[calibrate3]
;Throttle (Mode 1)
max=3698
min=489
zero=2093
[calibrate4]
;Rudder (Mode 1)
max=3867
min=569
zero=2218
[touch]
xscale=197312
yscale=147271
xoffset=-404
yoffset=-20

while calibrating, make sure you make the whole circle with the sticks and make sure your trim buttons are in the center position.

EDIT:
P.S. If you have calibrated your tx corectly and the x600 still is not flying ok, then you can calibrate your x600, by pushing both sticks to the lower right. (could also be lower left.)
