I don't want to scare you at all, just to remind you that you will really need to pay attention to the way you solder the encoder to the 9x mainboard.. If those diodes are supposed to.be connected across the motor pins, then the cathode (black ring) connects to positive.. João Sent from my BLN-L21 u...

Yep, open source rocks.. I use ErSky9x instead, which is equally powerful..
For example on my IC powered models, I use a pot to tune the engine idle, instead of the trim switch. I find it quicker to set by the right amount, when needed

João

I think Mike said that I already used all the connectors in the 9xtreme. I have bluetooth and I have haptic in process... So I think the only option I have soldering to the processor. I will make some small PCB too for it. In that case you will have to connect the encoder exactly as I did on my boa...

The encoder normally should be connected to some processor pins through some resistors. But as you have the 9xtreme board, I think might might have a simpler solution using the I2C connection and an extra little arduino board.. I believe he mentioned it somewhere. Please watch this video carefully. ...

Wonderful, thanks

João

This is what I built for my plane.. You can read about it here:

Yes.....already downloaded the OpenXsenor.....thats my final plan. At the Moments my need is to measure the Amps-hour consumed by my Helicopter.....just need a simple current sensor. That is what openXsensor can do. It doesn't connect to the receiver via A2, but over serial. I have built an oXs sen...

Don't know what else to suggest as I don't have the radio in front of me.. perhaps the attached pdf file helps.. Please have a look.

João

where did you get the power for the level converter from?

João

EDIT: Forget it, You said above that you have 5V on the inverter.. What's wrong with me today?

Sorry, I was confused. For a moment I thought you had the 9XR-PRO radio. But it seems you have the old 9XR.
That is what I get for not paying full attention to what I am reading. I do apologize again.

João

make sure the Telemetry COM port is set to 1. also try inverting it.

João

Thanks Mike. Will this "graph.bas" script work on other radios??

João

Please do a search in this forum for openXsensor or oXs. It is a sensor based on an arduino pro mini board. You can build it with many sensors, meaning you can build your own vario, current sensor, RPM sensor, voltage sensor, etc. You can also monitor individual cells. You can have several sensors c...

Definitely, specially if it could also be applied to other radios

Mike, by placing the interpreter.exe file in the eepskye directory, why not accessing it from eepskye itself?
Or does it work like that already?

That was my first thought also, but then I had the feeling he was talking about the radio itself.. Language barrier probably.
Since I live in Germany my English got a bit worse I guess

You need to measure the current from the radio itself? If so the radio, at least with Ersky9x, already measures its own current because it has already a sensor. It is R9 on the PCB where the module pins are. This sensor gets broken quite easily though and some 9XR-PRO radio users had to solder a wir...

Haven't we all??
For example, I think it was the first time I have seen damaged processor pins (with buttons) start working with external pullup resistors. I think this fix was attempted in the past, but it never worked. I might be wrong though, but I just don't remember

João

I think so, I wouldn't trust that chip anymore..

Cleaning hot glue is the easiest task in the planet
Just use some alcohol.. It will come right off.

Thanks Mike, need to have a look at that as well

Mike, if you implement it perhaps it could be placed in a "statistics" menu?

João

I did have a question about the telemetry mod reading through old threads. There was some mention of needing a resistor to use the trainor port afterward, but I don't know if that is already covered in the information given??? The trainer port has nothing to do with the telemetry mod :) You might b...

I do agree with you.. Model picture, should probably only show in one screen. But I think model name should show always.. In my opinion, we always need a little confirmation of what model we have loaded.. Extra safety for people that forget things fast, just like myself :) ;) João Sent from my BLN-L...

I am looking for information on modifications that is up-to-date. I have found alot, but some information seems to have been lost, or the pictures are missing from posts. First of all, be very welcome to the forum.. :) Yeah, the wiki is not working anymore unfortunately, probably because of securit...

Reading the table you posted above we can see that the pins 11, 12 and 13 are sinking the voltage to ground. So it means they are damaged. Probably when doing the HV programming or by some ESD.. Perhaps adding a 10K resistor as Mike suggested could make them work but I gotta say, I have seen this pr...

You should have posted here before about replacing the chip.. we would have suggested the m2561 instead. it has the double of the RAM of the m128 and m64 also :) My suggestion goes also to use Er9x instead of OpenTX. OpenTX is not being developed or maintained for the 9x board anymore as far as I kn...

I tend to agree with you on getting another chip.
Your resistance readings seem normal.
Can you do something else please?
Measure the voltage on pins 11, 12, and 13, while the radio is ON of course buttons pressed, and not pressed.
Be careful not to short anything you shouldn't

João

I don't know why, but I find a NiMh battery more adequate for a TX than a LiPo battery. Perhaps because I would never charge a LiPo battery while in the radio..But I would charge a NiMh without any problems..

João

You might have damaged the pins while removing the chip from the board, or during the HV programming.. Did you use them for the HV programming?

João

But that is not a LiPo battery, it is a NiMh battery pack.. Still, you need to know what is the minimum voltage the Taranis accept. if it has low dropout regulators you are ok, if not, you might need 7V minimum. Also, you need to consider the minimum voltage from any external RF module you connect t...
