The Deviation project is definitely catching on in China now. This thread in a Chinese forum is even growing faster than the thread here.

You can revert to original by upgrading the original fw and library with the dfuse tool.
They can be downloaded from the Walkera site, or here are some direct links to them: http://rc.fdr.hu/devo.php

i have devo 6 and i from what i can gather this software allows me to use rx's like these flysky but i went back couple of pages and saw that i needed a mod or a module to my tx for this to work. Could anyone link me to more info about this. Also will this enable me to use all 8 channels on the rx with my devo6?

Well, hopefully they'll appreciate the support for Chinese glyphs then. That was a lot more work than I expected

what about using other modules like frsky? would another transmitter be required for their protocol? if so would their DIY kit work and would you be able to switch to and from it from the software? I believe it requires a PPM input.

I'll eventually get around to adding support for the CC2500 module (which is needed for frsky among others). The instructions will likely be much like the Flysky instructions (you'll need to buy the module from ebay/aliexpress though). I have no ETA for that though.

What I'd really like to do is to design a module which has the 4 current RF chips (nrf24l01, cc2500, cyrf6936, A7105) with a single power-amp and antenna that could plug into the existing CYRF mounting point. That is a big project though, and not likely to be one I tackle right away.

Seems your well on your way of forging "The One TX to Control them all"

A friend pointed out this whole devo hack thing so I hit google.

First comment: Great work

I downloaded the src and have started going through it and would like a few clarifications just to make sure I understand the architecture of this thing.
1) for dsm2, is a new packet sent every 10ms (found in DSM2_Initialize())?
2) Is there any synchronization between the mixer array Channels[] and the generation of a packet? The reason I'm asking is what prevents the mixer from being part way through a calculation when an irq grabs partial data from the array

see doc/DSM.txt. The 10msec you see in DSM2_Initialize is just the delay of the 1st callback. Each time the callback is executed, it returns the time till the next callback execution.
new data is sent every 22msec, but we send each packet twice:
Code:
 0msec: Transmit channels 0-7 on channel 'a'
 4msec: Transmit channels 0-7 on channel 'b'
11msec: Transmit channels 8-14 on channel 'a'
15msec: Transmit channels 8-14 on channel 'b'
22msec: Transmit channels 0-7 on channel 'a'

Nothing prevents this, however the update (for a given channel) should be atomic (since it is a 16bit write). There is, of course, the potential that 2 channels depend on the same source and only one of them has been updated when the interrupt happens, but we oversample to a huge degree, so (a) the difference is likely to be incredibly small, and (b) it will be short lived, since the packet will be updated again 22msec later (2.4msec for Devo)

I have this problem:

I have the walkera DEVO 10 when I turn on the unit it beeps and i get a saving please wait message, then it goes blank and does the same thing again, about 1 second between beeps, here is a photo of the screen, I've tried switched in different positions, ive tried updating firmware, downgrading firmware and nothing works.

Any Ideas???? please help

Can this be fixed somehow on my end with reprogramming it or something of the sort?

You mean with Deviation firmware installed? or with Walkera firmware? Are you upgrading both the firmware and the library? I had that problem when trying to upgrade the stock Walkera Library, I accidentally hit the upload instead of the upgrade button. Which then overwrote the new library with the old library from the transmitter. Which then caused the transmitter to behave as you describe. I had to delete the (devo 10 lib 0.0.x.dfu) file and download a new one from walkeras site. Then make sure to use the upgrade button, not the upload button for the library.

But if you're talking about Deviation firmware then I have no idea, but I think it does not support devo 10 anyway.
