No, definitely I don't mind. I sat staring at the signals all my free time for 2 weeks and was very glad when after innumerous tries it finally started breathing. But it can be tiresome and I'm glad that you took part in finishing it up.

There are still puzzles, may be more of theoretical value. I don't believe that the XOR sequence and these XOROUT constants are stored somewhere in the chip. I think they are byproduct of some calculation, may be of CRC itself.

I can't upload test builds right now, but if someone wants to test, here's some source code:
bitbucket.org/goebish/deviationtx/branch/CX10A
There's a "Format" protocol option for CX10 now, default is Green, select Blue-A for blue board, CX-10A, CX-11 ...

It must give a serious kick, when trying and see it works!

Test builds:
www.deviationtx.com/downloads-new/catego...-10a-blue-board-cx11
(don't forget to set a switch for rate, channel 5, because it defaults to low)

@SeByDocKy, next on the list is EAchine H7, closedsink has figured out a good part of the protocol already, but we need captures from at least one more stock TX to move forward ;)

I am going to test it right now... But I have a question on ch5. As far as I see in code:
    if (Channels[CHANNEL5] > 0) {
        if (Channels[CHANNEL5] < CHAN_MAX_VALUE / 2)
          *flags |= 1;
        else
          *flags |= 2;
    }
- there can be three real values for low two bits: 00,01,10. And reflecting ch5 values are "zero or below", "positive but below smth" and "above smth". Where smth - some constant to calculate (may be 50?)

May be it is simplier to have virtual ch5 mapping as "below zero", "zero" and "above zero"? Or smth with borders about plus/minus 33 or 34.

I am interested in this specially as I will test on cx-10a which has upper rate to be headless mode on stock transmitter.

That's not my code but that's how I interpret it:

chan5 < 0 then flag= 0 (low rate)
chan5 >=0 && <50% then flag = 1 (mid rate, or high rate on cx10a)
chan5 >= 50% then flag = 2 (high rate, or headless on cx10a)

You mean Eachaine H8 "mini" ?

H-m-m... Suddenly... While my cx-10a was found completely discharged, I tried those new protocols with all the 5 quads I have uncompatible with devo.

The first result: DM007 suddenly flyed away from me as response to CX10-Green reinit and throttle check. :)

That's really greate as DM007 for me is much more interesting than cheersons 10/11. I will continue testing with it.

The Eachine H8 is a very interesting machine to be Deviated, because his protocol is the same as BayangToys Quadcopters.
The BayangToys X6,X7 and X9 are awesome flyers :)

Cool, I don't know why but I though the H8 used a nrf24l01 and was already deviated ...
hmmm I might get one then :p

We are talking about the new Eachine H8 mini (also called JJRC H8 mini in other sites):

@Goebish
If you want an awesome mini, buy an Attop YD-829 :P

Ok H8 is not the same than H8 mini, that's where I got confused.
I won't get an Attop YD-829 because it's almost working with Deviation already (just need a capture to understand and fix a few things).
I'm only interested in "toy grade" models that have not been deviated already.
Hacking them is where I get the fun, I prefer 250-450 sized fpv multi when it comes to flying :)

Makes sense to me :)
BTW, if you want more challenges, I can capture SPI traces for HonTai Quadcopters using XN297 (HT F801, F802, F803 and his variants with camera or Wi-Fi FPV). They are awesome flyers also and no deviated :)

Comrades, here is my report on DM007.

It works with CX10-Green protocol. AIL channel should be inverted. Flips - ok (ch6 value should be changed momently not permanently). His original TX has two rates: L and H. They corresponde to two lower rates on ch5 (I used 0 and 33). The highest rate (100 on ch5) - is unavailable on stock TX. It is awesome. :) Flyes really greate. Much better than with stock TX.

What is unresolved? Camera - photo and video. And headless mode. If I am not mistaken - there are no channels above ch6 now, aren't there?..

Anyway... I had a very-very complicated day today... And these are the first entirely good news for me today. So it's time to drink beer za zdorovie of all deviation developers and all the community. :)

Great! :silly:
I will capture ASAP. I know a lot of people will be happy specially for the HT F801. It's a great Sport flyer :)
