charging circuit of my Tarnais X9D + no longer switches off when the battery is full.

Hi Guys, The charging circuit of my Tarnais X9D + no longer switches off when the battery is full. It keeps charging even when the battery is full up to well over 9.8V. My original battery boils well over 9.8V without switching off. I use the original power supply and the 6 cell NiMh battery. Has an...

Re: deported air speed sensor

Hello, I asked myself the same question two years ago. and made a test with 5m silicone cable 30AWG ... I split my OXS sensor into two parts. The Arduino Pro mini with power measurement sits in the front of the canopy, easily accessible for flashing. The second part with MS5611 and Do4525 is in the ...

Re: Airspeed sensing with TEK probe and diff pressure sensor planned?

Hello, my mount is a simple CFK tube adapted in diameter to my pitot tube, so that it can push more tightly. Since you have given yourself a lot of effort in the construction, I think it's more for scale sailors who have plenty of space. It is much smaller and daintier than your very elaborate const...

Re: Airspeed sensing with TEK probe and diff pressure sensor planned?

Here is an example of my own construction pitot tube (replica).
Diameter 3mm and the whole is sunk for transport in a narrow hull pocket

Re: GPS sensor

I think it is a module in which nothing can be written in the Eprom.
there are several of them I also have a M8N where the config is fixed.
But also some where you can write normally in the config, even firmware updates.

OpenX Sensor with ADS1115 and MVPX7002 issue Airspeed reset

Hello, I have built with OpenX an Airspeed Sensor with ADS1115 and MVPX7002, Version : 8.2.3 But there is a problem with calibration. In windstill the display is not 0.0 Kmh, it shows about Positv 5-8Kmh or negative 5-8Kmh. When I start Airspeed Reset PPM 100 it changes from Positv to Negative or Ne...

Re: Advise on GPS alternatives

I have already done some tests with Frsky GPS V2, SM GPS Looger and also OpenXsensor and I think this log should clarify your questions. You can see very well that all the values at the landing go to zero. Only airspeed is not quite at zero, that is from the wind at the slope. The same test with Frs...

Re: GPS sensor

The Gps works so far with OXS. It forgets however after a couple hours that I have Galileo and IMES switched on. What code do I have to add in the GPS.CPP? This is the current code from me. // send config commands to GPS at 9600 bds (default baud rate) void OXS_GPS::setupGps( ) { const static uint8_...

Re: GPS sensor

Hello,

Is it possible to write the config GNSS with OXS into the GPS module?

Problem:
I have an M8N that loses its config after a few hours.

Then missing with always about 10-12 satellites

Re: Problem with the IMU 6050 and OXS

First times thank you for the quick explanation. Sorry for my many questions ... OK, So what I have understood so far, the IMU transmits in OXS V7 some angles and in the V8 it is possible to change in acceleration when linear is switched on. As far as clear. What I still do not understand yet ... Th...

Re: Problem with the IMU 6050 and OXS

To understand better what I have done. Here is my setup: RX Frsky Arduino Pro mini, Nano and Uno for Test OXS V7 Sensors: GY-86 with MS 5611 and IMU 6050, GPS M8N, Airspeed 4225DO. The transmitted values are: VSPD, ALT from 5611, ACC X, Y, Z from the IMU 6050, : Airspeed from 4225DO , GPS: Position,...

Re: Problem with the IMU 6050 and OXS

About the drift, can you also make a test without looking at the telemetry fields on the TX and using the arduino IDE terminal. In the file oXs_config_description.h , it is explained in section 12 how to proceed to get the Acc offsets from the imu. You have to uncomment the line #define DISPLAY_ACC...
