Generally, raspberry pi devices connected to other devices will (by
default) use python for their programming. The python libs have all the
setup and tear down code built in. You can use C as well, so I see no
reason why FPC couldn't be used. It's probably going to take some work
though. Yo

On unix (and all of it's derivatives, everything is a file, including
connections to other systems. You can treat it like a file, and in
(most) circumstances, it will operate just as if it were a local file.
Some devices require special handling, but for the most part, if it's

I need to read and write data to an EEPROM connected by I2C on a RaspberryPi4.

The data on the device is organized as 256 pages
