README: py-smbus
Prerequisites:
Be sure to build and install the lm-sensors userspace first. This package
requires one of the header files from that.
To build:
$ python setup.py build
To install (will also build if necessary):
$ python setup.py install
For general build/install help:
$ python setup.py --help-commands
Frequently Answered Question:
Q: It's throwing exceptions, nothing works, what's wrong?
A1: You need write permissions to the i2c-dev devices. Try running as root.
A2: Addresses in Linux/I2C are the most-sig 7 bits, right-justified. E.g.
if your device uses address 0xc0 to write and 0xc1 to read, then use
address 0x60 with this module.
A3: Some other kernel driver has claimed that I2C address. Unload it first.
