I have 4 separate voltages I want to read and display on my TX. I use an FrSky RX with OpenTx on TX16S. For testing, I have one potentiometer between VCC and GND with the wiper connected to A0, A1, A2 and A3 (all 4 are tired together for the test). My goal for this test is for my TX to display 4 ide...

I wonder if you can be more specific than "doesn't work very well" :=)

I gather this device does the same job as the 4017 circuit: http://www.alofthobbies.com/frsky-sbus-decoder-1.html

Use master branch, it is used for bugfixes and holds the 2.0.x development. The next branch is for development of 2.1.x and is unstable. Thanks. Here, You can build the circuit from the picture linked here. http://openrcforums.com/forum/viewtopic.php?f=84&t=5067#p71918 You don't need the transi...

Another question--can I control the number of channels that my Taranis outputs on the trainer port? Does it just output the first 8 channels from the MIXES page as CPPM, or can I control which channels go out and in which order?

Ari.

OK, right. I see the problem with haptic. I like the idea of using trainer pulse train. I am less enthusiastic about the number of components that this needs--either a decade counter and a microcontroller RC switch, or a complete uC. If I'm going to program an little uC to decode the pulse train, I ...

Well, this didn't work. I thought haptic just turns on, but it pulses. The up pulses are too short to trigger the 2260 RX. The TX has an LED in parallel with its modulation line. I can see it pulsing when haptic activates, but it's on for shorter than it takes to send out a valid packet and the RX r...

Thank you Mike. This line confused me. I guess it refers to pull up/pull down if the pin were an input.

Oh, I guess REVPLUS means build for Taranis Plus.

My other questions remain :=)

The interference seems to happen with antennas in either orientation. My sample size is too small to say how much better range I get with orthogonal orientation. I hear also about people trying to use an external XJT module to obtain 32 channels, and getting the same telemetry problems. The more I t...

If you're going to plug a wire to your radio, I think it would be eaaier to plug the same wire to an external switch somewhere. A footswitch for example. With a switch to arm in serie with it of course.. João That's a solution. I'd like to take advantage of logical switches in OpenTX though. For in...

This project might be of interest to you: http://openrcforums.com/forum/viewtopic.php?f=5&t=4611 Mike. Thank you Mike. Indeed it is, although for a different project. I have enough channels that I can spare a full channel for ignition control. My problem is trying to support diverse RXs and kee...

2. One type of aircraft I fly are rocket gliders. They go up on solid-fuel rockets and come back as regular R/C gliders. Ignition in these gliders is typically from a large, ground, lead-acid battery. Ignition control is with garage-door-opener type TX. I want to control this TX (a single button to...

Thanks Mike.

Now for the software side--do you think anyone else would like a Special Function that said "toggle GPIO X," or am I the only one with this use case?

Ari.

Thank you for your suggestion Mike. Where do the I2C pins come out? Is the main firmware using them for anything?

Ari.

Hi, I've had my Taranis for almost a year now. I'm enjoying it very much. I'm running 2.0.13. I understand that Teranis has a number of unused GPIO lines. I wonder where they route and how hard it is to control them. Ideally, I'd love something like BackLight or Haptic: an output I can activate from...
