Thanks PB!

I'm not all that bright so please feel free to smack me upside the head, but I was thinking, is it possible the the noise could be a result of a higher resolution of some kind. I mean, if the noise is consistent on all the gimbals could it mean you can read the values faster and it would actually be more accurate?

Again, I really don't know what I'm talking about, it just seems that on a $400 tx we would expect to see better gimbals resolution rather than worse.

I see that kind of noise all the time in er9x. I almost never see the numbers holding still, it's always flipping between -1,0,+1 etc. I then remembered reading something about gains needing adjusting when people installed the Aurora 9 gimbals in the 9x.

Anyway, just throwing it out there, I'm sure you've been over the problem many times.

Cheers

My 12s is at the office so I can't test until tomorrow.. :(

I battled with it for a longtime. I thought there was something wrong with my initialization since all other Devo Tx have very low ADC noise. But no, on the Devo12 it is just really noisy. Some channels are worse than others (Aux6 and Aux7 are nice and quiet for some reason). I think they just didn't isolate the signals (or perhaps the power-supply) properly on the Devo12. In any case, I don't think you'll notice. I didn't slow down reaction time any, I just oversample by 100x and average those values. so rather than sampling 1 time each 5msec, I sample 100 times over those 5msec. We still lose 1 bit of precision compared to the other radios, but it shouldn't be noticeable.

PPM with Phoenix is working fine, and the voltage looks good. The stick values are holding nice and steady.

Cheers!

Forgive my ignorance but am I to take it there is a stable build as to which this can be flown on reliably? If so I need to get my 12S on order. :)

It's still a bit early... but as I said, Phoenix Sim is working on PPM output. I was also able to fly my blade nano with DSMX protocol. That's all I've been able to test so far. Tonight I will try my v120 and my blade 300x.

LOL! That was fast... I'll post the details in another thread so we don't clog up this one any further.

There is any hope that it will be implemented?

Probably eventually. The code is really slow to execute, and so needs ram backing for the map-table. That means a lot of re-coding for me, and it will only ever be useful on the Devo12. It is too complex for me to deal with right now though.

1) Input monitor show inputs only up to AIL DR1. Not exist: AIL DR2, THOLD0,1, TRAINER0,1, FMODE0,1,2, MIX0,1,2, GEAR0,1. Possible we need 2 pages for Input monitor.

2) If I touch TFT screen, displayed voltage dropped on 0.08V

3) We need signal for neutral positions of all dials. For example, AUX6 and AUX7 dials haven't tactile signal for neutral position.

1) Interesting.
I just built an emulator for Devo12 ( look at this thread ) where the large amount of inputs was a challenge too and I could only solve this by splitting the page.
I think it could also work on a 320x240x16-screen as used today effectively in Devo12, but I am not sure if all switches will have space... the dials will have.
2) This is the price we pay for accuracy :P ...everything is noticed. I think a little drop can be explained with the touch technology.
3) You mean some kind of acustic feedback?

I want my Devo12. Can anyone persuade my wife?

Yes, point 3) is about sound feedback for neutral position.

I have checked in a version where the inputs are separated in two pages (analog and switches) for the 320x240-resolution in my repo ( see here ). It works for Devo8 but I can't test with an Devo12 if because I have none.
Maybe not all switches are shown because the screen is still not big enough ( I think 18 will be shown from existing 21). If I would know that it works so far, I would do the rest (splitting again, putting some switches to the analog inputs, make it smaller - we will see).

Hi guys at all, where can I found the system file (*.bin) for devo12s? I hope that somebody can help me!?!
Many thanks to all.

Take the file system for Devo8 - they are still identical.

*.bin files for Devo 12s. What is it? Walkera model setups?

Any chance you could make the Alarm for the TX voltage adjustable or at least drop it to like 3.5 volts as having it go off at 4 volts on a system that runs on 1S lipo (4.2 volts) is a bit short of a time frame.

You can change it in the tx.ini file.
These are the defaults, but you can change them:
batt_alarm=4000
batt_critical=3800
