It does explain it well, but you know how sometimes you aren't %100 sure and you just need a trusted voice to reassure you....
That was you. Thank you, again!

I actually think I have 2 questions: Q1) the following are the settings for my heli throttle including throttle hold line 1 Ch1 Thr 100 CV3 !RUD >>>This is saying to use CV3 when THR is on line 2 += Thr 100 CV2 !THR >>>This is saying to add CV2 when !THR is on???? line3 := MAX -100 ELE >>>if ELE is ...

Aye. I tried to upgrade to the newer build and it had some bugs so I downgraded to maintain reliability, and then never looked at upgrading again. I'll be switching to ER9X/Ar9x soon, anyway.


Thanks again, y'all!!!

Which screen is "inputs"? I dont have one labled as such.
I do have screens labled "dr/expo" "mixer" and "limits"
Ver 2940

I have OpentTx on a 9x and I'm slightlty confused/forget. In which OpenTX menu screen do I finally limit the actual throw of a servo? Mixer screen? or Limits screen? What is the effective difference in limiting the weight in the mixer screen vs the limits screen? Thanks for humoring me! *Edited for ...

Also, xjt and 9x *is possible.. i thinkhttp://jb0.de/?p=298

Debating on upgrading my 9x with AR9x and M9's OR scratch building a radio case like this one with an UNI and M9's https://www.rcgroups.com/forums/showpos ... stcount=15

that way, I would have the 9x with dsm and also custom with xjt...

...How is this issue fixed in the AR9X board?

Or is the AR9X chip less picky about digital vs analog ground, and it doesn't matter?

ahhh, that totally makes sense! (as it pertains to just switching a single ground wire around)

I haven't traced it out on the schema or in my tx, yet, but rather than cutting traces and soldering jumper wires, wouldn't it be easier to just remove horizontal trim gnd wire from the plug that goes to the mobo, and piggyback that to the digital ground wire? Or are there other components tied into...

Thanks! I had no frickin idea that was an issue. I was brand new to 8ch+ tx's when I got the 9x, and didn't find any major issues like this (obviously, I missed this one!) when researching before buying. So, I have to cut the ground trace for the horizontal trim buttons, and reconnect them to the gr...

So not cool! F22 scratch build dtfb/stick plane, orangerx switchable dsm/walkera module, opentx 2940, turnigy 9x, spektrum 6xxx rx. I crashed my f22 and had to retrim the plane. While trimming out ailerons (mode2) my 9x just...rebooted. i only got to press the trim switch 2 or 3x and bam, reboot. Pl...

perfect answers.

Thanks!!!

OK!
Jhsa:
why would I want LCD extension with AR9x?
Original 9x LCD/backlight works with new board?
What is "programing S-port device from transmitter"? Where is the S-port device located (Tx module? rx?)?

Thx! TTYS!

I'm sold on the idea of the AR9x, at this point it's a matter of budget and time. Soon... I keep asking about m64/m128 chips because I have a walkera donor tx that I'm going to convert with an m64, and then maybe build a teeny tiny one for fun, just because I have the parts. I really want to learn p...

That's what I thought. I was hoping I was wrong. Lol

Thx!

Jsha, can I add bluetooth to atmega64 for er9x? I found a couple threads where it was discussed (including you), but never saw where a how to.

I know AR9x will do it.

Oh, I don't know that I found suitable devices. But cruising throught ebay and digikey, I found a few for $6-$16 that looked like they might do the job. Honestly, i think I agree with Kilrah about a center position and if it skips for some reason are two drawbacks I would not be willing to risk. Tha...

The pots in transmitter gimbals are finicky to find replacements for (because they need to be 0k-5k over only 60* of rotation), and there have been many threads on many forums concerning the topic. I see now that some manufacturers are using hall effect sensors and there is some debate over sufficie...

Dude, that is sick! I have a few questions, though: what is the real time clock for? er9x for the ar9x has programming for extra buttons built in? is it setup/selected in the 9x, or in the firmware before you flash? what are the 4 buttons on the back for (what do *you use them for)? Does internal mo...

Let's pretend I'm going to build a radio based on a 9x processor.

Which ER9X image will support XJT telemetry and voice?

Thanks, again!

Thank you, but this is more of a pet project/desire/learning experience. I already have a 9x capable of running ER9x and supporting the XJT telemetry.

I just wanna build a badass radio to show off, I guess..... posterity, that sort of thing.

I do appreciate all the info, comments, and advice!

Bear with me, please: The 2560 and 2561 are not "compatible" for this application? What is the important difference? ****EDIT* The pinouts are different and obviously programming would not interact as programmed for the other chip.*** I have since started found the 9x clone thread and will...

WAIT!!!!!!!!!!!


I see there is a mega2561 build for ER9X. I assume this can be flashed to a diy 2560? same schematics as the OpenTx DIY 2560?

Am I right?

Dernit. I had delusions of using of using XJT in a DIY Mega2560 radio...

Que sera

I've looked and keep finding only older posts. I'm hoping someone here will brighten my day with an unexpected "yes, it will work" Very simple question: I keep seeing that a 9x radio+OpenTx+XJT module will not properly display telemetry data on the 9x lcd. Is this the case? I know a co pil...

I don't get it.

What I do "get" is using a switch with different curves set up.
Bam. Problem solved....alternately.

LOL!
I specifically remember that box about offsets from when I read that manuak.

I also remeber having trouble "getting" it and thinking "screw it, I won't need it anyway"


Karma comin back around, reaping what you sew, etc...

so the offset value is 0% to 100% with a "-" value being inverted....OK! Let me simmer with that for a while.

Thanks!

Step away from my original question for one moment and correct me if I'm wrong, please: When I use P1 as my input it is giving -100 to +100 over the whole throw of the knob. When I involve an "offset" value, that value is added to the value low value (-100) of the input (P1) for the output...
