Ok, than you have solved the problem. The thing is, unless the switching point of the engine killer switch could be programmed, you couldn't use the throttle channel. If you could program the switch to switch at a given pulse from the receiver, then it could be possible to do it using the same chann...

Jim, I am just trying to understand what you want to achieve so we know how to help you

I understood that it is a petrol engine, and there should be an ignition system that is controlled by the radio, just like on my plane

João

I have been following this thread and i got the feeling that there is some misunderstanding here. What I think he wants is: As an example, his throttle servo MIN / MAX movement ranges for example from -60% to say +80%. So at idle will be -60% He did a mechanical implementation with some kind of spri...

There is a MOSFET providing reverse polarity protection.

Then it shouldn't burn anything, providing that there aren't any design flaws of course We have seen them before

João

Mike is still a 9x open source firmware developer many of us still use the good ol' 9x radio with and without upgrade boards

João

Mike, anything new apart from the support for the other radios?
Anything needing special attention?

Thanks

João

Thanks Mike..

João

Yes it is, or an arduino Pro-mini

I just had another look at the schematic I posted for using N-Channel Mosfets, and although I might have tested them I think there might be a problem. They might not turn completely ON. The P-Channel Mosfets will work. That is what I have built for myself..

The older D8 is more of a problem as it is not legal in Europe for new products.

But it can be used with an external Multiprotocol module, right?

João

Jim, are you able to do soldering and program Microcontroller chips or arduino boards? Also, are all channels used for control surfaces, or are some being used for other stuff like lights for example? I am asking because there is an electronic project that allows us to control different equipment fr...

ErskyTX supports scripts on the 9XR-PRO, not LUA though.

Have a look here. At the end of the video.. it is for Ersk9x but OpenTX works more or less the same way.

The Atmel processor has a synchronous serial device available to generate the XJT protocol for the external module. The internal module connection only has a PWM device. It used to only do CPPM, but I did manage to get multi and DSM to work. It may be possible to get XJT to work but needs some new ...

I think the problem is that you would have to swap the "Physical" pins. Not just in software...

Weird, the only thing I could think that it could mess up the programming like that is if someone changed the stick mode in the Radio Setup, but even that wouldn't change a control that was on a vertical stick to an horizontal stick.. this is what doesn't make sense to me

João

Good that is all working. Could it be that'you copied the models from another radio?

João

Hmm, don't know if I understand your programming, but it looks like you have the motors forward /Backwards on the left horizontal stick (Rud), and left/right on the right vertical stick That doesn't look right?

João

Hey, I had forgotten about this thread :) I ended up giving up on the isolated switching regulators, connected all grounds again and left the 78M09 in there for each output. Added some PTC for protection, and that is it. Due to the isolated switching regulators max input voltage limitation, I also m...

This is what I use on my radios 9x with 9xtreme, Skyboard, and Ar9x. It is a soft power switch for both internal and external RF modules.

João

Then you might have changed something on the model's programming
Try downloading your model to your computer via Eepskye, and post it here please.

João

What radio do you have?
And what software it has installed? Ersky9x?

João

Let's find out if it is a gimbal problem.
Please go to Radio Setup / DiagAna menu..
The first four lines are the gimbals. Do they work there?

Finally you did it Mike It took you a few years
I like the new name
Thanks
João

The test version is stable, you can use it. Your radio doesn't have maintenance mode, and can't also play music. Those are features of Ersky9x that runs on more powerful hardware, not on the Atmega64 :) You might be able to get two extra switches connected to your voice module. Then you can configur...

Great.. Bad speakers can happen.. Or perhaps that one had a higher impedance, therefore the volume was lower??
Anyway, well done.

João

be careful, I wouldn't use protected cells, specially in the models :) You are asking for trouble. You see, the instant power from the LiIon cells are much less than LiPos. meaning that there will be a greater voltage drop. if the voltage falls under the cell protection's threshold, the cell with tu...

First of all, Voice pack. Follow the link, download and extract the voice files to the root directory of the SD Card. There is a doc file with the file list.. https://www.openrcforums.com/forum/viewtopic.php?f=5&t=7717 I have build the 2 boards of Arduvoice but not voice listening and BackLight stay...

Kilrah, perhaps, as I said above, my 18650's were just bad.. I bought them in some kind of promotion at Banggood.. I need to get some from HK, remove the protection and solder them to see if those don't get damaged.. I am very quick soldering batteries. Large tip and hot. Tin the batteries, let them...

the problem with the 18650 cells, as far as I know is that they don't like to be soldered, and could get damaged quite easily.. I had bad experience with some from Banggood Not sure about those ones from HK.

João

EDIT: Oh, these are protected cells.. I would not go for them then
