python-smbus

[vitalik2]

I would like to integrate a display via i2c and use with python. Unfortunately I can not find a python-smbus package. How can I create such a packet? (Or could someone create that?)

Take a look at the extension making section of the wiki

I try to compile python-smbus and get always this message:

Can it be that the gcc.tcz in armv6 repo contains the wrong version of gcc?
because of: /usr/lib/gcc/armv7l-unknown-linux-gnueabihf/7.1.0/include-fixed/limits.h:194:15

I do not know what to do with the error

Hi vitalik2
Did you install  compiletc.tcz?  I think you might also need  i2c-tools-dev.tcz.
