BME280 module

[theweissguy]

I'm trying to run a BME280 (IC2) on a PI3. The IC2 connection checks out so hardware looks ok. Attempting to run the Arduino eample:

#!/usr/bin/python
from Adafruit_BME280 import *
sensor = BME280(mode=BME280_OSAMPLE_8)
degrees = sensor.read_temperature()
pascals = sensor.read_pressure()
hectopascals = pascals / 100
humidity = sensor.read_humidity()
print 'Timestamp = {0:0.3f}'.format(sensor.t_fine)
print 'Temp = {0:0.3f} deg C'.format(degrees)
print 'Pressure = {0:0.2f} hPa'.format(hectopascals)
print 'Humidity = {0:0.2f} %'.format(humidity)

generates an import error "No module named Adafruit_BME280". I've followed the Arduino instructions for the GPIO and BME280 downloads/install but the results don't seem to make sense. Has anyone run this program successfully? If so how do I install the correct modules/libraries?

generates an import error "No module named Adafruit_BME280".

Your script cannot find the Adafruit python module.
Did you download the module from https://github.com/adafruit/Adafruit_Python_BME280?
If so, can the script find it.

The easiest would be to copy the module to the same directory as your script

[theweissguy]

Did the download, installed the unzipped files. Ran the program in the installed directory/sub-directories. Same error. Do you actually have this working? If so what is your directory structure and content that contains the working Adafruit_BME280_Example.py?

No, I don't have it working (don't have a BME280), but I have a fairly good idea how Python looks for modules (understatment alert )
What files are in the directory fro where you run your script (is it actually the Adafruit example script you try to run)?

BTW: you mention the Arduino instructions, but I hope you realise you're trying to use Python code that is meant to run on a computer (Pi) that has the BME280 directly connected. No Arduino in sight there.
Have you followed the instructions from https://github.com/adafruit/Adafruit_Python_BME280?

[theweissguy]

Yes I've followed their instructions, ambiguous though they are - e.g., " run the following command from this folder:
python Adafruit_BME280_Example.py". The folder is never specified hence I've tried many possibilities and none work.

cd to the directory where the py files are stored and execute the command.

Doesn't work -

Anyone else?

Gee, I can't wait to get kindly responses like that, for taking my time to help a stranger.

Oh, wait. Yes I can.

I intended to help you solve the problem but apparently my input is not appreciated.
Good luck and goodbye.

Sorry you feel this way - thanks for trying but you didn't solve my problem. Best that I can tell from internet searching is a rather laborious process of running an Arduino simulation on the PI and converting the BME280test.ino to run on the PI (https://robidouille.wordpress.com/2013/ ... pberry-pi/). Trying it later.

you should spend your time learning how to search internet
it would be much better spent than this sort of topics.

PS: my BME280 is working like a charm.

Care to share details?

Even the crappy forum search finds lots of stuff about BME280s
