My CP2102 looks like this: http://i.ebayimg.com/thumbs/images/g/fSIAAOSwZG9WjLkL/s-l200.jpg It has a minimalistic design - the chip itself, a couple of caps and 4 resistors. That's basically it... The reason I bought an FTDI is that I couldn't find a way to invert this CP2102. I remember my first FT...

No luck so far... I borrowed a D8R (just to be sure). It bound to my XJT set to D8 mode by the DIP switches (radio is set to PPM). I can control a servo connected to the receiver. So this part is certainly Ok. But I still cannot get it to talk via RS232. I suspect it could be because of the inversio...

Thanks!

Will certainly try it later today!

Mike, Which RS232 adapter did you use? I did it in a similar way as you described, but omitting the BIND and the servo part. I don't have a D-series rx, so I didn't test XJT was actually in D8 mode. But the DIP switches were set exactly as you described (ON-OFF), and the protocol in the radio was se...

I have the Arduino-based STK, FTDI and a CP2102. I just tried both the FTDI and the CP2102. But I got no success with neither of them. I also tried another XJT, but still no luck. I must be doing something wrong... :( Hmmm... Can I maybe type in some commands via a terminal program (i.e. Putty), jus...

Mike, Do you know if I can power XJT via its RS232 connector? There are the Rx, Tx, Vcc and GND. And when I apply 5v from USB, the module powers up and starts to beep just as if it was powered from the radio. So I suspect this should have worked... Unfortunately, it didn't work for me. I was unable ...

Oh! I forgot to mention that other than the beeping, the module seem to work Ok. It binds to receivers, shows pretty good SWR (about 2 to 16, depending on antenna position) and does its job quite fine (at least I didn't see any issues so far).

It's just this beeping that worries me...

Hi, I was given a strange XJT that always beeps whenever power is applied. Even if the model is not powered on, and even without PPM / PXX stream coming, it still does its beep-beep-beep-beep... I guess it's either some internal alarm (though, I'm not sure what it can be if it beeps even without the...

Kilrah,
Am I correct assuming the next RC of OpenTX 2.2 will have the S.Port connector +5v power enabled by-default? If so, do you know when the next RC is expected?

Then it's probably the easiest thing to do.

Confirmed! There is a brief 5.0v when trying to flash an external device. But it's really brief - I'd say less than a second. So if OpenTX will have this port switched ON by default, the algorithm of flashing an external device should be updated. The flasher should wait at least several seconds for ...

I'll check again tonight, but as far as I recall it timed out immediately - I had no chance to measure the voltage.

Didn't Mike already confirm it should be 5v?

I am ready to measure it if you tell me how to do it.

As I said, so far flashing of SPort devices didn't work for me in OpenTX on the X7.

Hmm... Ok!
There are pins soldered to the SPort connector on the radio I was asked to look into. I suspect the pinout is already correct there. I measured the GND and SPort pins and they seem to be the same as in the ext. module bay.

The switched power should be 5V on the bottom SPort connector. I believe, by default, the power is switched off, and only switched on when doing SPort device updates. Mike, that's great to know! Thanks! I guess the best solution would be to have an option to switch the bottom port between Always On...

Thanks for the hint! Do you know whether this port on the bottom is controlled separately from the external module? I guess it is, as even with the external module enabled there's still no power on the bottom SPort connector. But then the firmware flasher should have three options (internal module, ...

Hi All, In the new Taranis Q X7 there's an S.Port connector in the bottom of the radio. The manual just says it's for 'future use', so it isn't clear whether it is operational or not... I was asked to connect an FSD (FrSky S.Port Dashboard) to the Q X7. I thought I will just use this port at the bot...

Hi All, I think I read something about it, but now I can't find it... I was asked for help to connect two FLVSS (FrSky's voltage sensors) on the same model. It's a multicopter with two independent batteries (one is a 6S LiPo, I'm not yet sure about the other one). I understand I need to change the S...

Hi Carl,
Thank you for the kind words!
Unfortunately, I don't have an X9E. So I can't say whether these gimbals will fit. Judging by how FrSky positions the M9, I believe there should be another model that fits X9E without the need for modification.

Well done! :) Regarding the throw. I tested several gimbals (FlySky / Turnigy, FrSky PR10 and the M9). It appears that the stock FlySky gimbals have the largest throw (just a little bit over FrSky PR10), while FrSky M9 has the shortest. But I don't feel that to be an issue, at least my fingers had n...

Hmm... I thought it was part of ersky9x since a long time!

Anyway, that's a great news! Thanks a lot!!!

If you will need a tester - I'll be ready to help in about a week (as I don't have my radio with me now).

Mike,

Do you think it's possible to teach SportSet to change SPort IDs? Then it will become the one and only tool for all Sport-related changes on a PC.

This is not urgent at all, of course...

Yep! That's a very precise definition, BTW!


P.S. With all the testing you do and all those variations, no wonder you mix the radios up!

The buttons themselves are soldered to the the board. Really?! :) Perhaps, it's been a looong time since you opened up your 9XR! :) uncleburls , Based on what was discussed so far, one of the possible causes may be a faulty microcontroller (that big square chip on the board). Normally, it could be ...

Thanks!

I'll check with Taranis owner and will report back!

It may take a few days though...

Right, I'm not looking for min/max value. This would have been too easy!

Kalle, thanks for the hint!
That's how I wanted to test it on ersky9x (don't have an OpenTX radio at hand now), but I wasn't sure if OpenTX is similar in this regard.
I'll dig it further then!

Dear All, I was asked whether it's possible to temporarily save some telemetry value, without needing to go through telemetry logs. A friend of mine is flying gliders. He wants his radio to "remember" how high his glider is at a certain point during the flight, and then he wants to be able...

Since the "Thanks" button seem to be gone completely, I'll put it in plain text: THANK YOU!!!
My modding mood is back to life!


Now, what new features shall we expect from the ATSAM4S8CA chip?

I think I read a few reports of a similar issue with X8R on my local forum. Though, no detailed analysis was done, so the cause of these glitches remains unknown. Also, a couple of users reported severe range reduction of X8R when working in an area with multiple 433MHz LRS systems in use. The same ...

Hi All,

I would keep a vertical line (or at least something) to indicate a physical centre of the trim line. Then the actual trim position indicator doesn't have to show the side our trim is off centre. This will allow to estimate HOW FAR it is off centre, which is useful sometimes.
