external input - Feature Request

[Whimsical]

Open TX has the 8 ppm inputs which is wonderful but in a 32 channel system a bit limiting, 16 would be a lot better.
I have the Taranis and it already looks a bit like a porcupine but i need more buttons
I will use an external module and receiver to get 8 more channels and am going to use an Arduino to feed some extra buttons and 2 head tracker inputs to the trainer port, i will mount it on the handle. I can get just enough buttons/ switches with the 8 ppm inputs but i can see in some setups i would want more. If the main board had more unused inputs i could add some of it inside the case but i don't think it has.
As OpenTX moves forward i think it needs to find ways to add additional inputs separate to what the hardware provider has supplied and ppm is an easy way to achieve this. Hopefully someone with better coding skills than i have will do a small board with lots of variable ways to configure inputs and companion software to make it general purpose for non technical users.

Hy,

there is a ready solution for that

with 7-8 switch or 8-7 analog Inputs or mix

look at 27. okt. starting

yes that provides 8 inputs and it would be easy to make it more than 8 and i will do an Arduino board to get what i want such as 2 head tracker inputs which are a PPM stream for each tracker. They will need disassembling and recombining into 1 stream for the trainer port.
BUT OpenTX can only use 8 channels with the PPM source as it is now. With 2 modules there are 32 channels and they can be assigned as liked but there is not enough switches pots or what ever in some applications. I am fine as 8 will fulfill my needs but i can see that won't always be the case. There are other multiplexors that give extra channels over 1 or 2 existing channels by increasing the latency but it seems to me more ways of providing inputs for normal channels would be better. The only way at the moment is through the existing 8 ppm selections.
Could that be changed to 16 PPM inputs?

OpenTX 2.0 will have support for 16CH input on ARM boards.

Kilrah My hero
That is via the ppm source selection.
Amazing done before i even asked

I tried to look at your code but you have to be a member of that site to download. I don't speak German so not much point registering at that forum. Is your code available anywhere else?

Hy,

here is the software
for Arduino NanoV3

and with opentx2.0 you can expand to 16PPM inputs

Thanks for that

Hi,

Can the taranis be fed with an external cpmm or sbus (via trainer input or other ...?) and map these to the rf-channels ?
The idea is to use 8 internal inputs (sticks and pots of the taranis) and 8 external inputs (cppm or sbus, ...) coming from another receiver / transmitter trainer port.

thanks

Yes, see my reply to your other question regarding more than 4 trainer channels.

Mike.
