SoloPro 260A Nordic nRF24L01+ spi module was created by blackmoon
I know this doesn't follow protocol request rules, but anyway...

Is it possible to port old SoloPro 260A to deviation ?

The code is already written by kile at RCG to run on an AVR.

Nordic nRF24L01+ module is SPI.

There is also a module with antenna :

But it isn't necessary as kile demonstrated on the thread linked.

I have a nrf24l01 module in my test setup, but I do not have a SP260 that I can use for testing. If I can get a hold of one (or at least an Rx) I could work on it.

I for one don't see the need for you to have the Rx (unless you wanna do some debugging), because the protocol was already reverse engineered by kile, and the code written for an avr in (I think) C.

I am using his module to pilot my three SP 260a and haven't had any issue, his code is rock solid.

For you porting it would be a peace of cake.

I would think if kile provided the source with a GPLv3 and deviation being an open-source project, he wouldn't mind.

Unless you are against using code from someone else, or you don't want your code under v3 (didn't look at the license you use).

Does it take less time for you if you reverse engineer it ?

Or you just want to be thorough and have it completely documented ?

I would offer to send you one of my SP boards, but you seem reluctant to it.

Mainly because you don't want strings attached, as I understand your point of view, I for one won't be the guy telling you "hey dude where's my protocol, as I sent you a board for it...".

I'm not that kind of person, I love contributing to open source projects, we need that kind of commitment and selfless act of doing things just to help others.

And as I can't program, I try to contribute with whatever is needed.

I reckon, I couldn't beta test it for you, since I don't own a Devention transmitter.

I'm stretched between buying a combo with devo10, or wait for you to complete the "devo7 enhancement" project.

Once again thank you for your commitment.

I need a receiver to test it. The avr code needs to be completely rewritten to work in deviation (even if I use it as a source). As long as the licenses are compatible, I am happy to reuse other folks' work, but the probability of it working after I'm done without any testing would be very near zero.

I've sent you a message regarding an Rx. I'm not keen to buy yet another 4ch, especially one that has been replaced by a newer model.

Hi - just curious in this as well. Is the support for this still in development or was it dropped?

I have the code written, but I am still trying to figure out how to hook up the module in a reasonable way.

Do you want me to design and make a small board which will provide multiplexing for CS signal? TMS and TCK is enough to provide a choice for 4 radios, though you'll need to disconnect CS from original radio and pass it through the board. 4 radios cover almost everything - CYRF6936, A7105, CC2500, and finally nRF24L01.

Forgot to add that CE for nRF24L01 can always be asserted - you can switch the radio via SPI and initially it's off.

well, we need to multiplex the CS and reset signal It could easily be done with a 2x 1:4 multiplexer. There are other issues though. Some modules need 3.3V and others require 5V. Anyhow, I just haven't found the time so far. If you put the circuit together, I can comment on it

Which ones are 5v? I thought there are no radio chips working on 5v, only 3.3v. It complicates it a bit, if it's so.

well, the CYRF696 module takes 5V (it has an on-board voltage regulator). I can't recall if any other modules work this way actually. All modules use 3.3V SPI

I spent a day or so working on getting the NineEagles 260 code working, but sadly while testing, I wired up the Heli Rx backwards, and apparently smoked it.

I'm not an expert with the nrf24l01. The code mine is based off of uses send and receive modes for the binding, but it also uses auto-ack, which I'd expect to be good enough to skip switching to Rx mode.

I used my programmable switch to control CE, which seems to work well.

The code is checked in here:
bitbucket.org/PhracturedBlue/rpi_protocols

I'll keep the code in case anyone ever wants to take a crack at it, but that is probably the end of my development for this protocol.

was waiting for a solo pro 260 code for a very long time, for years literally. will it happen though? because if its not gonna happen, ill just have to change the RX of my bravo sx. pls. give us un update.

It looks unlikely now. While the code likely only needs a small amount of work to finish, without any way to test it, I can't make more progress. Since this Heli is no longer very popular, I don't think there is much chance of completing it.

oh ok, its an old protocol anyways plus the board's gyro is out dated, rolls are sensed as yaw too.
