Hi. This here shows a bit of my 'standard' oXs. IMG_20210116_193421.jpg RX, oXs with MS5611 and an ACS712-20A current sensor., placed between battery and controller. There is a distance between current sensor and oXs, so I can place the oXs with the baro in a more 'quieter' place. There are 4 wires ...

Good to hear, it is OK now

I tested cell voltage years ago, but never used it in real.

Total voltage is sufficient for me.

Loaded the two config files from your first post.

Inserted those here, flashed the code to an Arduino uno, activated 'debug' and that is, what I see



That looks ok.

OK.

Attach both config files here and I will try....

... and found out my FrSky receiver I bought together with the transmitter (V8R4-II, never used either ), probably needs to be replaced for a new one.

Why Hugo?

8 channel RX. For a start, it should do.

what you thing about "in case Arduino can not handle"; using other controllers like teensy or stm32 based bords?. This question has been put forward a long time ago and several times. But you have to remember, mstrens is, more or less. the only one, who is putting his work into the oXs project, whi...

Get used to work with u-center before fussing around with oXs and GPS.

And when no USB UART is around, just use your Arduino to connect your GPS to u-center.

I think, it would be easier, if you attach the complete oXs_config_basic.h and oXs_config_advanced.h file here as attachments

br KH

A short search in the internet --> XC6201P302PR

br KH

You have been through this here?

oXs_config_description.h

A very comprehensive description about oXs.

When I run the engine on the ground I get perfect, sensible read outs on my Horus all the way through the rpm range but the moment she is airborne the readings are all over the place That sounds strange.

So If I understand it wright I don't need the own Taranis firmware on the Taranis website because OpenTX is replacing the Taranis firmware ? You are still mixing things. https://imgur.com/LaQKhq3l.png There is only openTX on the webside. (And the HF module firmware) - There is the transmitter opera...

Was playing a bit with the SxR and thinking of putting it into one of my flying wings (replacing the standard rx), where the designer requests some differential. No idea ....

On the other hand I am not sure if it would be critical or not to use the 5V data / signal line (from a nano) to the 3.3 V data / signal line of the receiver.

Which RX please?

br KH

Yes, but the Nano is bigger, just like the blue pill ...

AND I DON'T HAVE THAT MUCH SPACE

The main reason I am not that happy with the Pro Mini board is, that the upload over a USB-TTL converter may or may not work. One shouldn't expect all are electronic experts, also some Pro Mini boards on the market have wrong/ reversed pins, some USB-TTL converters causing problems uploading while ...

Updating OpenTx without using Companion?

So the simple answer is NO!

Hi João. Would prefer the Maple Mini (left one). But the size compared to the Pro mini! https://imgur.com/7UUVDLtl.png The one on the right, that is NOT a genuine Pro mini, but has a LGT8F328P. A bit faster than the original 328, End of the year I am going to do some tests with oXs on those. br KH

Hi Thomas. Did you see this post here? https://openrcforums.com/forum/viewtopic.php?f=86&t=12903&p=151388#p151388 Cappy used a 32U4 and mstrens (the oXs developer) answered that. Mstrens is not answering in this forum at the moment, maybe he is on holiday. Hopefully he does not have to fight Corona....

Better make a fresh installation with LM 20 on your computer.

Hi, would like to ask a question about the Configurator. After years doing the oXs configuration with an editor, had a little deeper look at the Configurator. MPX + GPS. With oXs ver. 8.0.6 those were the MPX outputs 10 , GPS_COURSE , 1 , 1 , 0 , -16384 , 16383 , \ 11 , GPS_SPEED , 1 , 1 , 0 , -1638...
