bme280's Issues

PIP install

Dear Sir

Tried to follow your installation description pip install bme280 and it didnt work, it didnt find the read_bme280 file, than I have found out that it did install it in some place pi/.local.

the fix for it was to use sudo pip install or run the pip install as root.

I recommend that you add this info for installation process to run as root or use sudo.

bme280.setup should avoid exposing bme280_i2c

Looking at the read_bme280 script, the minimal script to read a sensor data from Python is:

from bme280 import bme280, bme280_i2c

bme280_i2c.set_default_i2c_address(0x76)
bme280_i2c.set_default_bus(1) 
bme280.setup()
data = bme280.read_all()

Instead I would expect the following minimal script, which would make it honor Python unspoken standards (cf. import statistics):

import bme280

bme280.setup() # or bme280.setup(0x76, 1)
data = bme280.read_all()

This avoids exposing the i2c class, so that once a SPI class becomes available as a backend, it'll be easier to switch.

Attribute Error

Hi
I use bme280 0.3 package. As "i2cdetect -y 1" command returns, my BME280 has address 0x77 and "read_bme280 -- help" command works well. But when I test "read_bme280 --i2c-address 0x77" command, following error appears:
Traceback (most recent call last):
File "/usr/local/bin/read_bme280", line 9, in
load_entry_point('bme280==0.3', 'console_scripts', 'read_bme280')()
File "/usr/local/lib/python3.4/dist-package/bme280/bme280.py", line 210, in main

File "/usr/local/lib/python3.4/dist-package/bme280/bme280.py", line 22, in set_default_bus
default_bus = smbus.SMBus(bus_number)
AttributeError: 'NoneType' object has no attribute 'SMBus'

Can anybody help me?
