Px4Flow on Cube?

Hi

Can I use a Px4Flow on a Cube?

Im trying to use it on the I2C port with this manuals:

https://docs.px4.io/v1.9.0/en/sensor/px4flow.html
https://ardupilot.org/copter/docs/common-px4flow-overview.html

But no luck.

@philip @Anubis ?

thanks!

Absolutely yes. It runs well.

The issue with the PX4Flow, is do you have a real one? Some of the clones were unreliable.

Has it worked before on anything?

What Lidar are you using with it?

What issues are you seeing?

Have you done the calibration?

When doing the calibration, the rotation is around the center of the sensor, not the Center of your vehicle

Make sure you have the correct firmware on your flow module

-I suppose.

Has it worked before on anything?
-I dont know, I have just get it from Ebay

What Lidar are you using with it?
-This are my first try with this, so im try it to make it work first. I get the bad optflow Healt and the opt_m_x and Y are solid 0. So no lidar yet, I want to make the optical work firs.

What issues are you seeing?
the sensor is not recognize

Have you done the calibration?
Yes, I saw the image on the qgroundcontrol and calibrate the lens.

When doing the calibration, the rotation is around the center of the sensor, not the Center of your vehicle.
OK

It won’t work right without a good lidar,

Focusing the camera, and doing the calibration are two totally different things

you mean without lidar the opt_m_x and Y will be 0?

I know, but I cant calibrate the sensor if I cant get the flow sensor work

Possibly.

ok, but this PX4flow has a sonar sensor, that I cant make it work to.

IIRC the sonar is not supported any more because it wasn’t reliable enough.

edit: from the Copter documentation for PX4Flow:

Although the sensor may be supplied with a built-in Maxbotix LZ-EZ4 sonar to measure height, this has not been reliable enough over a range of surfaces in testing, so its readings are not used. It is recommended to purchase a PX4Flow device without the sonar. Instead a separate Range Finder such as the LightWare SF10b should also be attached to the vehicle.

Get the lidar… follow the instructions
