Hi Martin!

Perfect also in FC9. :)

Saw you have fixed the BM180 also, I have order one, look forward to play a little with this also. See in other fora that it should be possible to measure heights with this device as well.

I am very grateful to you.

Jorgen

Hi Jorgen, you're welcome.
To be honest, If I was you I would use the BME280
I used that to measure heights/Altitude.
It also has humidity and temperature sensing.

Hi again!

I know the BME280 well and know it works in FC, used it the other day, but of course I will follow your advice Martin :D Now I have order one, so I play a little with it ;)

Hi Martin!

As promised, when I received the BMP180 I would test, just received them, and hereby, thank´s. I have mad a quick test. I work perfect, but some of the regulation setting in proporties doesn´t make change, the temperature x1 > x16 I don´t see any changing by playing with this. The sleep funktion how does they work, and if the device "go in sleep" how do I wake them up again in the program :lol:

Are you kind to give a short explanation for these, and maybe upload a testprogram to Wiki, you are welcome to use mine :P

And any correction in my test is welcome.

Hi Jorgen.
I have looked at the datasheet and temperature oversampling is just a trade-off between accuracy, current drawn, and sample time.:

In reality, you probably won't see that much difference if not using a battery.
If you are using a battery to power BMP180, then you want the lowest setting.
As for the sleep, it's to save power when not sampling, it will wake up when being sampled, then go back to sleep.
