Contiki File System (CFS) and Coffee Examples
|
|
|
|
|
=============================================
|
|
|
|
|
|
|
|
|
|
Coffee is a very simple, relatively small and easy to use file system that you
|
|
|
|
|
are most likely going to be very familiar with if you have done any C file
|
|
|
|
|
access in the past. The notion is the same as on a normal PC: you open a file,
|
|
|
|
|
read and write to it and close it. Contiki will take care of the underlying
|
|
|
|
|
flash memory, giving you more time to focus on the real issues.
|
|
|
|
|
|
|
|
|
|
Coffee is a full implementation of the CFS API.
|
|
|
|
|

An extended explanation on CFS and Coffee internals and how they work can be

found at the [CFS](https://github.com/contiki-os/contiki/wiki/File-systems) and

The examples are known to build for the 'avr-raven' platform. However,
|
|
|
|
|
some of them currently fail at runtime due to file system overflow.
|
|
|
|
|
Tweaking the file sizes in the examples is necessary.
