JJRC H20 Hex Quad

Two additions for the Supported Models spreadsheet. I can't add them so I've tried to format them so they can be easily added.

JJRC H22 quad NRF24L01 H8-3D

Other good news, the actuall protocol binds the JJRC H11D & H20C. But actually, we need to add a lot of functions
- video
- photo
- Headless
- Onekey return
- Reset (gyros calibration)
- camera tilting

I need to capture the associated SPI data

Any idea when H20 is going into a nightly build? I've a bit hesitant to install the "working" version into my Devo 10. Got everything working so good as is, nervous to try something that's in "debug" stage -- or is it? Also, how do I install the H20 protocol? I've only installed Deviation and the nightly build.

Hi guys,

Really big fan of all your hard work. Eagerly awaiting the new nightly release to be able to fly the H22. I can't use those tiny remotes and use forcefly on all these. Thought you might care to know.

I've updated the combo build with the protocol changes in the latest pull requests.

With the last Hubsan protocol update too ?

I've just merged a few of the pull requests that had two approvals - that's the usual criteria. Merging the H83D protocol created a conflict in the H7 pull request...

Since the official nightly build is not currently being updated I've set up a test build titled nightly_default. It should automatically update the night after pull requests are merged.

It's really a good news,thanks Hexfet!

Hi,

first, thanks for your work!

I'm a newbie in deviation, quads, and in RC general. I flashed the hexfet-combo-build yesterday to my Devo 7e to be able to fly JJRC H20 (and Eachine H7). JJRC H20 binds and fly, but it spins around itself. I tried to fix it with the trim-buttons but it doesn't seem that it will ever be stabilised or centered. I used the model.ini from here www.deviationtx.com/forum/model-configs/...jjrc-h20-hex-devo-7e , but also made one myself - same problem. Now I've tested the stock transmitter and with it it's perfectly stable, no spinning at all. Of course, I calibrated the sticks on the Devo 7e, and I can fly Hubsan X4 and Eachine H8 mini without any problems, so I'm not sure what I'm missing. I'm also not sure if it's related, but the H7 continously moves forward. Any ideas what I'm doing wrong?

edit: I ran out of ideas, so I started from scratch: I formatted the devo 7e filesystem, flashed the 2015-10-25 nightly build and copied the files from it, after that I flashed the combo build and copied the protocols/* files from it. Unfortunately, the result is the same.

edit2: I tried the test build from this thread instead of the latest combo build, but result is still the same.

I've the exact same problem when controlling the H20 with Devo7e. The quad spins left & right and never stabilised no matter how much trim I put. With stock controller, it's rock solid. It looks like this protocol is a bit broken for the H20.

Was working fine when I tested ....
