I don't checked it, but it very likely can happen. Probably, X-Plus channels have sense for Devo12 only.

At any case, early or late, we need refuse from full support for Devo7e.

I was on the wrong track. The values are changed outside the protocol option page - no need to force something.

Vlad, is there a direct dependancy of the values? Esp. is the resolution a changeable option or given by the DSM2/DSMx-protocol and the number of channels used? If so I would not show this as an option.

And what about Devo10? There are enough user inputs to control additional channels...
We should introduce a "#define HAS_DSM_XCHANNELS" or similar in the target_defs.h files and add the X-channel code conditionally.

With current implementation of DSM2/X protocol, without parsing binding responce from Rx, we must select resolution manually.

I think we need implement X-Plus channels for Devo12 only. For other Tx it has not sense.

Hi. How about the Devo8? It has 18 inputs excluding trims.

I can see only 16 inputs including trims at Devo8. Buttons can't be used as input.

4 sticks, 6x2 trim buttons, 6 switches = max 22 inputs

I have nothing against that, we can implement it in all Tx except devo7e. But in reality, it can be used effectively only with Devo12.

...and Devo10.

I see no reason why we should add more differences between the deviation implementations than what is necessary from a technical /ressource view. If such a feature is usable shall the user decide. It will cost more to maintain the differences.

I can imagine a config where X-channels are used, but not all regular channels (X-channels are for switching lights and gears, was writetn somewhere). So the number of inputs needed may be less than the highest used channel number.

I would like Devo8S if you can do it. Happy to test too. May I ask how you have implemented X1 and X2? Are they 9bit copies of Ch11 and Ch12?
Thanks, David.

You can read about it in X-Plus channels documentation

Thanks. I've seen reference to 20 channels so I assume you've implemented this as 1-12 normal + X1-X8. It is my understanding that Spektrum only send data for 18 channels with X1/X2 the same as Ch11/12 but with different resolution. I don't think this is a problem; just seeking clarification.

Vlad i do have a Devo10. I think there are not enough inputs to need x-channels, but i can test it should it be necessary.

In the "final version", what do i have to do to get xchannels enabled?

At protocol options you have to select 'X-Plus channels' = 'On', then you can change number of channels up to 20.

You don't need change 'DSM2 resolution'. If 'X-Plus channels' = 'On'and number of channels > 7, 'DSM2 resolution' will automatically change to 'Step: 2048'. You can see it if next time visit protocol options page.

We need change names to fit Devo10 interface:

Firmware for Devo12, based on v3.1.0-beta-04 rbe2012 build

DELETED

Devo12 filesystem

DELETED

Firmware for Devo10, based on v3.1.0-beta-04 rbe2012 build

As I have written here or in my repo: if you choose values which start with a number and change the values, they are changed in steps (of 1 if both values < 200, 10 above) so you will have a very long way from 1024 to 2048.
But you are right, should be shorter. BTW: leading blanks do not help...

Now I see this problem, it's corrected. Also, with DSMX protocol 'Resolution' always will be 'Steps:2048'.

Last version dsm2.c file:

DELETED

I see one problem with Devo10 emulator - protocol options do not changed to conditional values if I do not scroll down to '# Channels'.

I think this is because something is changed when the channel number field is calculated (maybe in numchanselect_cb()?).In this case there can be a difference in Devo8 where the channel number field is visible and Devo10 where it is not.
If you send me the code I can have a look.

Code attached in my previous message. At any case, it's only for testing X-Plus.

Didn't you make any changes outside of dsm2.c?
