Message-ID: <CAFoiVO3MetN1eh=zwinHjRDPXOZ=n0bPiF75y0D42zdxn-_Tog@mail.gmail.com>

Hi all,

I'm working on a resource which reads weather data, and I'm using this code
to read data from a BMP180 barometric pressure sensor.

https://github.com/lawsie/barometric-sensor

The code in the file bmpBackend_py3.py (and the Adafruit I2c/bmp085 files)
was originally in Python 2 and I converted it using 2to3. However this has
resulted in the bit shifts not working any more in the readPressure()
method.

This code works in Python 2 but I need the resource to be in Python 3. I've
included the Python 2 bmpBackend file too for comparison in case the tool
has changed something odd.

I predict the problem is to do with the redefinition of the / operator from
2 to 3, but I don't know enough about bit shifting to figure out what to do
to resolve it.

Would anyone be able to help me to get this working? :)

Many thanks,
Laura

Just to add to what Laura has said. This resource is part of a global
weather experiment. We have 1000 schools around the world taking part and
we want them to be able to program them with Python as well as with Java.
Helping with the conversion from 2 to 3 would impact a lot of young people!

Thanks,

Carrie Anne

Laura,

I may be missing something, but it looks to me as though Adafruit have 
already done this for the modules you're using. The repo you point to at 
the head of the backend file:

   https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code/

describes how they've broken the code out into smaller repos and made 
them work with Py2/3.

Certainly

   https://github.com/adafruit/Adafruit_Python_BMP

and

 
https://github.com/adafruit/Adafruit_Python_GPIO/blob/master/Adafruit_GPIO/I2C.py

seem, by inspection, to be 2/3 compatible.

I'm happy to help, but is it possible that you're re-inventing the wheel 
here? Or have I missed something?

THANK YOU Tim! Sometimes you can't see the wood for the trees - I inherited
that old code and it didn't occur to me to see if someone had since made a
Python 3 Adafruit library. That works perfectly and is super easy to
install and use.

The Barometric Pressure sensor *shall* go to the ball! :)

Hi, don't know how I came to receive this email, and didn't see that you
had it solved until after playing with it ... but the problem is shifting
bits on a float ... needs to be an int.

Do you teach? Do you Python?

The deadline to submit your talk proposal to speak at the Python Education
Summit is on January 3rd. More details on the submission process here:
http://bit.ly/2hxv4HO

We can't wait to hear what works (and what doesn't) in teaching Python,
whether you teach in a classroom or teach through the written word.

Join us for an awesome day full of Python AND Education with educators from
around the world @ the annual Pycon Conference.

Respectfully,

Chalmer | Jessica | Meenal | Ria
