Re: current sensor

i will give you mine humble opinion, In the future use the VCC, 5V , or 3.3V for Vref instead of Internal ref. You will gain resolution in the measured value, and don´t need voltage dividers. The ACS712 only accept 5v of supply, not even 3.3v. Assuming you are using the bidirectional version at 0 am...

Re: current sensor

OK, from what i understand you are using the internal voltage reference. I never did that in any of mine projects, because the IC is powered always above the internal voltage reference, in the case of the atmega 328. You don´t need 6 values..the 6 values are for voltage reading,not current reading! ...

Re: current sensor

Hello ronron84, The voltage levels accepted by the atmega328 from the arduino depends on is operating voltage, 3,3V or 5V. So the ADC can´t get higher voltage then the supply voltage. If you are powering the current sensor from the 3,3 or 5,0 volt you won´t get problems. In that case you put : #defi...

Re: PPM_SPORT Mode, not found VSPEED

Hello, There are two ways to change the sensitivity of the vario (MS5611). Either with #define PPM_VIA_SPORT or #define PIN_PPM This also works and VSpeed is found as a sensor in both cases If you now also use AIRSPEED_COMPENSATED, then in PPM_VIA_SPORT mode no more VSpeed found, when using PIN_PPM...

Re: OpenX sensor + GY-86

I’ve just received a GY-521 module (no BARO or Magnetometer) & once the calibrations were set up, this appears to be fine at the Tx once small offsets (0.2g) were added in the FrSky telemetry screen. Display resolution reduced to 1 decimal place for ease of readability. AccZ reads 1g, whilst X & Y ...

Re: GY86 no IMU data but Baro still ok?

Dear mstrens, Thank you for your great support and many thanks for your persistence with my inability! This test was successful, I was able to read out the sensor and also recalibrate it. So the ACC is in Life! Now I also changed also some settins in the script, I changed the INT to Pin3 = #define ...

Re: GY86 no IMU data but Baro still ok?

I´m sorry,

I thought that you didn't solder the INT pin of the GY 86 board....yes, you can connect to Pin 3 of the Pro mini..If you declare it of course in the config. file..
Please check if that pin isn't assigned to any other thing...

Re: GY86 no IMU data but Baro still ok?

You need to solder the INT(interrupt) to Digital PIN 2 of the Arduino Pro Mini clone, if you don´t do it, it will not work!!!!

Please try it....

Are you using a pro Mini?..Are you sure that is 5V 16MHZ, and not the 3.3V 8Mhz?

Hello Eaglefly,


Do you have correct accelerations outputs in X,Y AND Z, because I'm having good output in Z but not in X and Y...
Do you use opentx?

OpenX sensor + GY-86

Hello Everyone,

Is someone getting good values, concerning acelleration of the GY-86 board with Openx Sensor?

I´m having good data in the Z acelleration using open TX, but the acelleration in X and Y is incorrect!

Can anyone give some feedback?

Best Regards to all.

Re: RE: Re: GY-86 not working - am I missing something?

some more points about your tests with the "master" release: - did you check that there where no other line in the config that asked for filling Test1 ,2 and 3 with other values than accelerations? - if you rotate your sensor, does the accX and Y change in a logical way?
