Spektrum problems in transmitter set up. Plz help

Feelers

Hey. Can't get my 2 weeks old quad tuned for 4s so said I'd try flash my cc3d with dRonin

Got to the transmitter set up, put in all stick inputs ok then got to the page to see if the controls onscreen mimic my spektrum dx9 radio.

But no matter what I do yaw left and roll left will not reconised on this page.
Nearly going to give up at this point but then found this forum so hopefully someone can help

What kind of receiver? Are you using a satellite, a normal receiver with PWM out, or something emitting PPM?

Feelers

mlyle thanks for the quick reply it's a satellite. Works perfectly on librepilot also

Feelers -- if the port is correctly set to DSM, you could look at the DSMBind parameter, and choose 'force 10 bit' or 'force 11 bit' and see if it's better.

Autodetection doesn't always work perfectly, so you can override the resolution for DSM2 / DSMX. We've improved the autodetection logic with guidance from Spektrum in the development code so this will be better in the next release.

Feelers

Anyone have this problem?

Feelers

mlyle but if I got to the the part were it asks me to reverse roll/pitch etc shouldn't it all work without have to change anything

Is the next release far away I'm getting annoyed with trying to set this up lol

Feelers

mlyle how do I do this

Personal experience: I've been playing with the radio in order to decide which knob to activate, which channel to use for TxPID, ... and consequently had to calibrate the radio quite a few times. It is indeed a pain to do all the calibration and then invert again min/max input (i.e reverse the channel) from the GCS. In the end I've reversed roll/pitch (yaw?) channels on the radio and it saves me quite a bit of time.

It is nice to have a reversing feature on the GCS in order to use even the most plain and simple radios, but as long as you have a programmable radio, you'd better use some of its features.

A word of caution for the flight-mode switch: check what is the flightmode activated by the fail-safe, and if need be reverse the corresponding channel. For me auto-level is with the toggle-switch on the down position, while the up position was for acro. When I tested fail-safe, I was surprised to discover it was mimicking a toggle-up...

Ok I put my other quad on Dronin and it picked up everything so I swapped out the cc3d and put it in the build I was having problems with went to set up transmitter set up and still the same. Made a new model on radio still nothing

Feelers

Ok I notice I'm all over the place when writing about my issue so this post will some it all up more clearly sorry.

Ive got a martian 230 frame with rs2205 2300kv and dys XM20A and I'm trying to get 4s to work. I have a cc3d on librepilot and after about a month I could not get it tuned for 4s, for 3s stock pids worked well. So I was going to scrap 4s altogether until I heard about dRonin yesterday.

So I flashed dRonin no problem went through the vehicle wizard hit save and that was that.
Then I moved onto transmitter set up, mapping roll, pitch, yaw, throttle etc.
The stick moved like mine perfectly, but then when I get to the part were it allows me to reverse channels to match what I'm doing on stick this were the problem Starts,
When I move the sticks yaw left and roll left the stick go all "limp" on screen and won't go left on either roll or yaw.

This is were the weird thing happens. I got out me spare a zmr250 with afro 4in1 20amp esc and mt2204 2300kv emax motors and cc3d and flashed that and all the set up including the above transmitter set upwork perfectly. And flies beautifully.

So then I thought maybe some of my settings on my radio for the martian was wrong so I made a new model in the radio went through setups again and stick the same, then I start getting annoyed! So I rip apart the zmr and get the cc3d out of that thinking maybe I got a bad cc3d on the martian but nope! When I had it all changed over wired up and done vehicle setup it's OK. But when I do the transmitter setup with the zmr cc3d that "worked" in my martian it's the same thing at the same points in the transmitter set up so not I'm just confused.

About to give up on this whole frame setup soon getting really annoyed haha!

Hooe someone can put me out of my misery!
Thanks

He came by IRC; it was the resolution thing (needed to be forced to 11 bit).

Feelers hopefully all is working well for you now.

mlyle

Go to the hardware pane, look at the field labeled dsm bind, and click 'force 10 bit'. If this does not work, try 'force 11 bit'.

From my own personal experience:
1/ DSM2 satellite are easily autodetected by the board, DSMx may require an adjustment of the DSMbind value as per mlyle recommendation.
2/ CC3Ds are easily overloaded whenever a lots of input channels are used. I experienced the hectic behaviour you mentioned with a 9ch satellite but not with a 6chPPM receiver. I suspect automatic calibration is just polling all the channels. In this case it is more efficient to perform a manual setup.

Radio manual setup
.Step 1 bind the satellite with an external receiver
.Step 2 if using DSM2, leave DSMbind to autodectect, otherwise (i.e DSMx) select "force 10 bit" or "force 11 bit" (whichever works for you)
.Step 3 on the input panel select DSM for (1)throttle, (2)roll, (3)pitch, (4)yaw and (5)flight-mode. Maximum 5 channels.
.Step 4 Click on manual calibration and calibrate one channel at a time, i.e do not make circles with the sticks
.Step 5 revert min/max values for roll/pitch/yaw in order to reverse the channels, or better reverse these channels on your radio.

Hope this helps...

Hello all I am also having problems with my tricopter build currently
I am using a kakutef4v2 and using rcexplorers setup with remapping the servo to led
I have came across a problem trying to use Dsm satellite and with this setup, on the rcexplorer forum page there was a post about a installer to fix this yet the drive seems to be outdated

here is the link where i came across this post
https://rcexplorer.se/forums/topic/dronin-for-tricopters-trironin/page/6/

If anyone could help that would be great

Whenever I use LemonRX satellite, once the satellite is bound to the radio I have to specify the resolution manually.

Resolution as in the dsmx bind value?
I have the satellite bound but its not communicating with the board, i think it is because of the tricopter version and the software involved from rcExplorer
