Might be you have to power on the radio with "Hardware Menu enabled" (even though it should appear in the Display menu; Left Trim left when powering on). My Display menu has the options of Contrast Brightness Light switch Light on Key Light on Stk Mv Flash on Beep Rotate Screen Reverse Screen BUT I'...

erSKY flash screen upside down.

In "radio setup" - "Display" tick the "Rotate Screen"

That will rotate your screen

I have Ersky TX (9xR pro) but no TX18S

Reinhard

If I install erskyTX for TX18S ... and somethings not quite right ? can the original openTX be put back ? I know that sounds ungrateful - its not meant to be. You can (and should) download the existing firmware and eeprom of your radio before you flash a new software. eePsky allows you that downloa...

In the past, I collected tips, that I thought, could be useful some times
I add a collection of possible mixes that control the speed of a servo movement depending on the stick position (ER9x/ERSkyTx as well as openTx).
Check, if there is something helful for you.

Reinhard

Check your switch.
Normally the common pin is in the middle and is connected either to the left or to the right pins.
That means, battery has to be connected to the middle pins and the modules to the right / left pins of the switch.

Reinhard

And you can do the preselection with a momentary switch Throttle cut switch is used for throttle cut, trainer switch is used as direction preselection switch For every motor direction you have the full range of the throttle stick (-100 to +100) The motor direction can be preselected at any throttle ...

And you can even do it without an auxilliary channel, al least with ER9x and ERSKy9x with the Latch function of the logic switches (don't know if opentx has this function too). L1 Latch LD LE LD v<val Thr -98 THR LE v<val Thr -98 !THR // onlly the last 6 switches can work with inverted switches (!TH...

I searched the forum for my old entries of how I have programmed my HK Phoenix2000 for ER9x and OpenTX (nowadays really old versions) With probably some minor adaptions, I still fly it with this programming. Different to your proposal, for craw I use ailerons up and flaps down. In the descriptions, ...

You can do it even easier, without curves
(I just recognized, that I didn't post the curves. Y-value of c1 goes from 0 to +100%, for c2 from 0 to -100%)

Replace the first two lines with the following lines

CH3 +50% Thr (L1) Offset(50%)
-50% Thr (!L1) offset(-50%)

Reinhard

I just stumbled over your problem and had an idea that I realized in ER9x, but I assume it should be possible in OpenTx also For the throttle channel you use two mixer lines, one using curve1, the other using curve2. These lines are activated alternating by means of the status of the logic switch L1...

Last thing during normal operation where Trainee is in control, I tested disconnecting the cable: the Trainer's software detects that it is an abnormal condition; even if I keep the TRN switch pushed, the software no longer takes into account the trainer port; it shortly hands the controls back to ...

As João said, the teachers radio must have the fully programmed model while the student radio has a simple 4 channel model without any further mixes. The stick values of the student radio will replace the stick values of the teachers radio and all mixes of the teachers radio will be supplied. So in ...

I will be doing so WITHOUT all the switches in place, and probably without the gimbals hooked up. I will get a switch error warning. No big deal, flip switches into correct... oh yeah there aren't any switches! :P "Or push any button" but that doesn't work with the encoder button. That's no problem...

When I modded one of my old radios, (https://www.openrcforums.com/forum/viewtopic.php?f=61&t=7180) that also had independent trim pots, I finally decided to add digital trim switches at the left and right side of the housing and with help of Mike, modified the code to use the analog trim pots as add...

Thanks Mike

Reinhard

Mike, could you, occasionally, push the latest modifications onto github ?

Reinhard

I downloaded the A3r223 fw version once more, compiled the mpm code 1.3.1.65 with multy_telemetry (outcommented some protocols) and now, the scanner is working !!!
And the mpm version is displayed with any protocol selection, not only wit AFHDS2A.

Thanks, Mike.

It's now working.

Reinhard

I can't answer this in the moment as I used the precompiled version. And compiling it myself does not work with the plain code because it's size is to big for the module. I have not yet found out how to disable the USB support that is expected now for the code to fit the module. I outcommented a bun...

I have a 9XR Pro (FW Vers.: ersky9x-A3r223 from 17.07.2020) with external multi protocol module, running in serial mode. The fw version (1.3.1.65) of the MPM is only read out, when I select the AFHDS2A protocol. Once displayed, it is shown with any selected protocol. Is this normal ? When I select t...

9x radio normally uses 6x6x9.5 mm tactile switches

e.g.

Reinhard

Thanks, Mike

this fix did the job.

No more 'No Telemetry' calls with the fully telemetry enabled module.

Reinhard

That's correct, but that's not a problem as I only use flysky AFHDS receivers that don't have telemetry.

Reinhard

No Telemetry is also permanently called with the open TX version.
But when I compile the mpm code with "//define TELEMETRY" then there are nomore calls of 'No Telemetry'

Reinhard

I had the mpm already updated with the recent precompiled version "multi-stm-ersky-reta-inv-v1.3.0.76" (but redid it, to be sure) No idea how that fw is compiled regarding MULTI_TELEMETRY or MULTI_STATUS. Nevertheless, without a telemetry signal available, shouldn't it tell me the missing telemetry ...

Mike, thanks for looking into that problem. You made me uncertain about my problem, so I wanted to verify it again.... and got ... no problem ?????? even with fw versions that I knew they had shown the same symptom. My 'dirty' temporary circumvention (as I do not use any telemetry) of that permanent...

I also use the "Save as" method to save the complete set of files that belong to a project. BUT there is sometimes a little problem (at least with my version 1.8.0). You can start the arduino ide either by clicking the arduiono.exe and it will open your last project. That's ok. You can also double c...

Ersky9x without telemetry using Flysky protocol By Chance I found the reason why one of my models was permanently telling me "No Telemetry" When the Telemetry Usr Protocol is set to HUBRAW the radio permanently, with maximum repetitionrate, tells you that there is no telemetry This Bug is there sinc...

Some time ago I got a Multiplex Cockpit SX transmitter with defective electronics. As the mechanics of that transmitter are really good, I was hoping to rebuild the required electronics in the way of the ER9x. I didn't want to have the voice module or a trainer connector as the original radio had it...

regarding to intermittend compile errors with the Arduino IDE There is/ or was? a problem with the linker (at least until the version 1.8.0 that I still use). I had the problem that least modifications of a file, e.g. adding a line of code or even deleting a commentline could lead to a "load error 1...
