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 [Coffee](https://github.com/contiki-os/contiki/wiki/Coffee-filesystem-example) wiki pages. Supported Hardware (tested or known to work) -------------------------------------------- * sky * z1 * wismote * avr-raven * cc2538dk * openmote-cc2538 * zoul 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.
