Traner port outputs PPM, and I think it is the same for every manucfacturer. Too tired to explain, have a picture. http://i.imgur.com/E8JvyGo.jpg Sorry thought the AnyLink leads were more complicated then they actually are. It was late :? I'll add the request in. Tried to open the .brd and .sch fil...

Will do Hman545.

JohnEdwa, what you suggest is possible. Can I ask what sort of signal is on the signal pin of the AnyLink system ? 5v push-pull, open collector, etc. ?

Cam.

OK, a few big changes. The project is now using hardware SPI instead of bit banging it, so anyone that has already built it you will need to change your circuit to work with the new code, sorry ! Transmit power is set to 100mW, nearly flat out. Also combined all protocols into one hex. At power up c...

The code for the FlySky protocol has it entering bind mode for a set period if the bind button is pressed at power up (or if the variable Model.fixed_id isn't set, I am guessing this is a menu option in deviation, it isn't used in my project), there is no back talking from the receiver, and it exits...

Having never owned the V939 you will have to forgive the ignorance, but what you propose is just like sticking the bind button down ? So at every switch on the Tx enters bind mode ?

Oh dear. This post over on Deviation spotted by Blackmoon refers to this commit: https://bitbucket.org/PhracturedBlue/deviation/commits/5b5a0db83c25ad2b33078179dcbcb90aaea1e823 Which is exactly what I added to the code. My code is based (currently) on a snapshot after this commit https://bitbucket.o...

All understood blackmoon. Please let me know if the fix works ?

Cam.

Yes blackmoon leaving DIO_PULLD disconnected should be fine. However in the next version of the code I am going to switch to hardware based SPI so direct pin to pin connection will not be possible when powering the CPU @ 3.3V. With hardware SPI the IO lines are separate and need to be combined. I su...

Good find, it would explain why mine works but not Kilrah's. I'll port the code over tomorrow.

Thanks for that.

Cam.

Hmm maybe break the link between RX/PD0 and ICP1/PB0, it could be the unimplemented PD0 pin holding the other low.

From memory if you get the Tx Rx switch on order wrong you get the solid lights but no control. Guess you have tried that though.

Cam.

Apologies all for the lack of replies. I stopped getting the email notifications for new replies, probably my fault for reading a new post when not logged in, then forgetting to check again, sorry. Some answers: Q: Can it support xxx model ? A: If it uses the A7105 chipset then with some software wo...

Excellent thanks, can I ask where the 20mw Tx came from ? Sorry everyone, off topic, I know.

Since reflashing my TX to swap modules wouldn't be very practical in the field! Yes, right got ya. I think another version of my module to support DSM2/X and Devo is totally possible. I will be able to tell more when the Devo module arrives. I know a lot of people have gone dual internal modules, I...

Hmm problem 2) sorted. See here viewtopic.php?f=5&t=362 and here http://www.ehirobo.com/shop/product_inf ... s_id=11530

I'll order one for a try.

All understood jhitesma, no bad feelings here, no pestering or complaining felt, as you were. I understand now the confusion with respect to 9x firmware integration. Yes you are right I have just pinched bits of devo code and used it in my totally separate module. More bad news though, the devo and ...

Hmm on the subject of Devo and DSM/X anyone spotted a cyrf6936 module ? Can find the IC's but not any modules.

Sorry to say but at least to start with this project is just going to be another module, not an all in one solution. Certainly no DSM/X or Devo support at the minute. It doesn't currently integrate with the 9x code in anyway because it doesn't need to. It's just like any other PPM module. I am quite...

Yes thanks. Pinout pitch, pcb, and shielding can dimensions would be good so I can generate the 3D model. While I have you Kilrah, I spotted your Hubsan X4 FPV video over on RCGroups, stunning !!! I am guessing the Tx was something like this ? http://www.rangevideo.com/index.php?main_page=product_in...

OK, I have ordered one for these modules mentioned by jhitesma http://www.ebay.com/itm/A7105-500m-wireless-transceiver-Antenna-nRF24L01-CC2500-SI4432-CC2530-/300777696218?pt=US_Wire_Harnesses&hash=item4607bf6bda if nothing else if looks like the biggest that will have to be accommodated, so ther...

Excellent, makefiles were never my strong point. Not enough linux as a kid I guess :lol: Your assumptions are correct Prof Moriarty, the unit is reading the PPM input signal from the transmitter, and I did that for compatibility with all transmitters. I hadn't considered any tighter integration with...

OK, the google code project is up: http://code.google.com/p/rc-ppm-2-spi/ PCB files are there, all source code, it's an AVR Studio V4 project, and a PERL script for decoding Saleae logic SPI csv's into something more readable. The code it beta-ish (as I have test flown it), the rest is alpha-ish. Cam.

I hadn't considered the range aspect of the upgrade at all and it wasn't the reason I started this. I simply wanted all my models on one Tx. That has been my sole motivation to this point. That said, it appears the module you linked will work with my hardware/software, and if the description is to b...

All those interior Tx pics are gold, thanks for doing that. They all look suitable but as you pointed out the Syma one certainly looks like reverse polarity from looking at the PCB traces. Your AliExpress module also looks a goer, it has already been used by a few people with deviation as you pointe...

Re-reading the description they do mention A7105 more than the others, but still I think you will have to have the shielding can off for a look see inside.

I understand what you are saying with respect to including the A7105 etc on my module but I have a couple of problems. I am not sure I would trust myself to design the 2.4Ghz witch craft PCB let alone assemble it so it had any range, so I can't expect others to be able to manage it. Given the price ...

Software is KiCAD, it's open source so free for all to use, once I get round to a Google Code page you will be able to get all the design files and give it a try. It is worth pointing out that in the renderings only the circuit board on the bottom is my creation. The one on the top is from my origin...

Didn't take long to route. Have made a couple of pin changes I want to check back on the actual circuit, but first,,, bed.

Today's work. Board isn't routed yet, just drew/found all the footprints and 3d models.

I'll get some PCB's made and distribute them to those who want one (once I have at least one working one). Not really planning on any ready made ones so brush up on those soldering skills ! It's gonna be SMT.

The module will control both the Hubsan x4, and the JP Twister Quad. I have test flown it with both. I can't say for sure on the WLToys quad as I don't have one, but from all accounts it and the JP Twister Quad are the same machine so I see no problems. It will also control the Nano Stik I mentioned...
