Hi guys,

I just received my Eachine H8 3D mini and was wondering if there's any news about this protocol?

The stock TX doesn't do it for me especially as I'm used to my Devo 7e.

Thanks for your hard work!

Hi, any progress on the H20 protocol? Need more SPI captures?

Deviation Devo7e 3way switch mod, A7105, NRF24L01
Devo6s 2x2 switch mod, trim mod, haptic, multimodule, A7105, NRF24L01, CC2500
Devo12e 4-in-1 with voice mod -- it speaks!!

On behalf of the mode 1 flyers, I was wondering the same. There is a mode 1 version of the H8 3D, and probably the H20 too, as these use the same transmitter, but they messed up and it's not really mode 1, but mode 3, as rudder is also on the right stick. So totally useless to mode 1 flyers. Deviation support wouid be the answer to their prayers, I think.

I just ordered a H8 mini 3D (same controller than H20) to work on it, but as I said I've seen in the captures that the controller is using auto ack... This shouldn't be a problem if it's only on TX side but if RX needs it too, the current XN297 emulation won't work, we may need Victzh help then

Good news, I received the H8 mini 3D this morning and it seems the protocol will be easy to implement after all

More in a few hours ...

Awesome news! If you manage to come up with a build, could you include the m99 protocol and bayang in it? Latest nightly?

Told ya you should have bought it already...

Awesome news, would make this awesome flyer available more people, and maybe even the antenna mod will be no longer needed to get 50+ metres of range.

Here's a test build (based on latest nightly):

7e: www.dropbox.com/s/dltp75gur2rae4p/deviat...0.1-55a4c76.zip?dl=0
10: www.dropbox.com/s/ttc2hcb88qmw11k/deviat...0.1-55a4c76.zip?dl=0
source: bitbucket.org/goebish/deviationtx/branch/H8_3D#diff

Protocol name: H8 3D

"High rate" only, setup D/R / expo as required ...

- Channel 6 = flip

- Channel 9 =
H20 : Headless
H8 3D: RTH then press a direction to enter headless mode, as with stock TX

- Channel 10 =
H20: RTH
H8: 180 or 360° flip mode

I got bad/missing protocol modules

Where did i go wrong? I have nrf24l01 module only on 7e.
I get that note only from H8 3d protocol. My other birds bind normal..

Procedure: Upgraded to your dfu and got all the other files from latest "v4.0.1-583c468" but the protocol folder from your .rar file. And before that backuped my model folder and hardware.ini

Ok, try to download again, I modified something: removed the space in the protocol name and replaced it with a dash... I'm never sure of those rules when creating new 7e modules ...

Works! Awesome man! Thank you! The ail/ele is mixed but i'm now going to modify it. I'm not gonna test the headless because i've never even flyed with it seriously. I personally think it's pointless. Im sure someone else will report that. I'm gonna report how the flips work when i reach there!

Ok thanks... rhaaa that means I still have ail & ele mixed by default in my Tx

I'll fix that ...

edit: are you sure the problem is not on your side ?
All is fine here with default mixer.

That's not a big deal. EDIT: I'm not sure but the bayang protocol does not have anything mixed. I had the v2x2 ail/ele inverted when i first binded that. So it could be my problem. Who knows.

I dont get the flipping. Does the 0 and 50 mean the scale in the mixer? I tried to put the inverted flip to SW B2 button and scaled it 0 and the 360degree flip to SW B0 and scaled it 50. It does only the inverted flip once and nothing else. It doesn't even flip itself back when trying to hit the SW B2 again.

Yes, this is scale in mixer, try with 25 and 75 instead of 0 & 50.
Also, with 180° mode, you've to disengage flip mode then re-engage to flip it again.

Please try, if it doesn't work I'll fix it.

I'm sure the flips work but i just dont know how to set the expo&dr. I've never done it before. I only done simple and complex. My noobnes strikes again. I've been stumbling with it and managed to perform both the 180 flip and 360 flip but not both in the same configuration.

Also, I think if scale is too low in a D/R configuration that will prevent flips from working...
hmmm, maybe I should implement "rate" as on stock radio after all, tell me what you think as there is a debate about a "rate" channel versus D/R only

Currently only my tx id is used, I'd need a few more logic captures to understand txid / rf channels relationship to complete the implementation, please provide some if you can.

I only have 2 sets right now, that's not enough to understand the logic behind.
TX ID / RF channels
AE B8 0B 10 / 0F 19 2F 34 (my tx)
AF C5 17 00 / 10 17 2C 33 (Deal57 tx)

Hi Goebish,

Just want to confirm that it works great!
Didn't have the time to test everything but flying is great and I have the flips working.

Still have to look for a solution to choose between flip or inverted because I only have 2 position switches installed.

Will look again as soon as I have some time.

Thank you very much for your hard work!!

Greetz,

Pesadilla
