Hello Matthew,
in theory it should be possible to use read / write together with some
ioctls to set the address. But normally I would suggest to create
i2c_msg structures for a finer grained control. Take a look at the
i2cget command for a simple example hot to read from an EEPROM like device:
the linux api is exported via cpukit/include/dev/i2c/i2c.h
the include path should be #include
I'm not aware of any good examples to follow. The embedded brains
folks have most experience working with it.

Hi,
The ATSAM BSP has I2C support, but i am slightly unclear about the API that
should be used to access it.
Using pread() & pwrite() seems to trigger assertions that look like memory
corruption in atsam_i2c_bus.c
The linux I2C userspace API seems to be suggested, which looks like
ioctrl(), but
