SYMA X5C-1, X11, X12

I need a Devo 10 to fly all my Syma stuff as well as Blade.
I don't feel confident soldering the nrf card for the Syma protocol.
Does anyone do this in the US?
I would like to buy a Devo10 already modified.

nightly builds

All the SymaX changes are merged to the deviationtx repo and will be in the deviationtx nightly builds .

Camera controls are moved to channel 6 (take picture) and channel 7 (start/stop video). Channel 5 remains flip control. Default number of channels changed to 5. Maximum channels left at 8 in anticipation of adding headless control after SBDK has a chance to gather data

I've tested with my X12. Would appreciate some additional testing. Attached is a build for 7e. This is only SymaX and yd717 changes added to PB's latest nightly. The deviationtx build will have all the other recent improvements made in that repo.

Just tested with my X11C. All working
Good job!

BTW, these changes are for the sub option X5C also?

Yes, same applies to the X5C option.

Thanks for testing!

Great job as usual If your new symax.c is already in your repos, I will recompile with my current build. I will capture the Headless channel asap I finish the review.

A little bit out of topic.... 2 other ultra popular protocol need to be updated

i) The V2X2 by adding a) the "headless" channel and b) a 250Kbit datarate option (for bradwii) exactly the same line you wrote for the SymaX->SymaX5C

ii) The Flysky protocol: I received a new WLtoys V686 reusing this protocol. Many new channels for camera, pictures, headless, pseudo-RTH, and flips .... I will try to capture these SPI data ....

You can find the latest on bitbucket under devationtx/deviation. My copy is at hexfet/deviationtx. With the work by mwm and indigo the deviationtx build is a big improvement.

Will be good to support the latest protocol versions

I can handle V2x2, I've seen the data there: www.deviationtx.com/forum/protocol-devel...ocol?start=300#28302 .

Why do you need 250Kbit/s for bradwii? Did I miss something?

Please victzh, take a look to my captures

I guess Seby want a 250Kpbs datarate option, to enhance the range.

BTW, another off-topic - X5C or Nihui U807? X5C looks more solid, U807 is more like Traxxas Alias (I like it).

Also, anyone tried www.dealsmachine.com/ ?

Nihui it's very cool, but is very new also. So no spare parts, at least for now, and totally unknown flying characteristics/Quality/durability.
Syma X5C it's a very known Quad. Plenty of spare parts everywhere at cheap price, and latest version (X5C-1 ) works great.

About Dealsmachines. I bought 2 times from them. First time send me a wrong item, and second time received without problems.
I guess they are serious, but have very slow processing order time.
Dealsmachines and Gearbest are very similar. In fact I have in mind they are the same company

Why do you need 250Kbit/s for bradwii? Did I miss something?

Just to increase range for such ultra cheap FC board to (almost) offer same capacities than expensive alienwii/luffro boards. The JXD 392 FC is a good candidate (good MOSFET for 8.5mm motors, 13 USD)
For example, the range of this new syma protocol working @250kbits have been greatly increased vs the 1Mbits version.

I already (badly) added this 250 kbits/ option for both deviationTX & Bradwii for a V262 board. The range have been widely increased.

I guess there is a

_tr_noop("250Kbits"), _tr_noop("Off"), _tr_noop("On"), NULL,

to add at beginning and in the init something like:


if (Model.proto_opts[PROTOOPTS_V2X2]) {
NRF24L01_SetBitrate(NRF24L01_BR_1M);
} else {
NRF24L01_SetBitrate(NRF24L01_BR_250K);
}

This requires modification of both Deviation module and bradwii-jd385 firmware. Not that it can't be accomplished, but clearly set goals help a lot. Moreover, for this combination we're free to use ANY nRF24L01+ compatible protocol, including our own .

Why do you think it's bad? Nothing wrong with the TX code, make a pull request. I would do exactly the same. Make a pull request for bradwii as well, I just don't know (lost grip) what repo is the most advanced now.

You are definitively sur-estimating my coding skills for DeviationTX & Bradwii... So I prefer to modify an existing one ...

After I am also dreaming to add a kind of telemetry to this V2X2 protocol
"à la" Iforce2D:



At least to have this count of ACK displayed in the telemetry field ...

Ive got my 7E modded and my X11 bound and very proud of myself! Any suggestions on why the X11 would slowly be rotating to the left? my trim buttons dont seem to be doing much. I can fly still fly it, but curious what I should do to fix this very slight rotation.

Thanks guys!!

Did you recalibrate the gyro/acceloremeters ?

edit* i recalibrated my sticks on the 7E and its working great now

Hi, I'm new to the 7E, in fact I don't have it yet, but about to purchase one. My primary interest is micros, and I have a Syma X11, an original X5C (not X5C-1), a Syma F3 heli, and a blade nano qx and a couple of V911's to boot.

What will I have to have / do to get this group on the devo. I'm technically inclined and have an electronics background, so some soldering is not a problem.

Syma X11 uses SymaX protocol, with nRF24L01 module installed.
Syma X5C (original version), uses SymaX protocol with sub-option X5C enabled, and nRF24L01 module installed also.
Syma F3, sorry, d'ont know...
Blade Nano QX uses DSM2/DSMX (sorry d'ont rememember now) protocol, with only the internal CYRF module, so not need to install any new hardware.
And V911 heli uses Flysky protocol, so you need to intall A7105 module.
