EI2C files
==========

Common files for the Python scripts using the I2C protocol defined in the VME
crates from ELMA.

ei2c.py       -- defines the EI2C class and methods for accessing a board within
              the VME crate

ei2cexcept.py -- exception classes for all the errors an ELMA crate can return
              when communicating over I2C

ei2cdefine.py -- constants used across the other Python scripts
              -- dump constant that is used within the ei2c.py module to see
              whether a dump file should be created when running a Python
              script; this dump file contains the messages returned by the
              ELMA crate when communicating over I2C
