The cFS is a platform and project independent reusable software framework and set of reusable applications developed by NASA Goddard Space Flight Center. This framework is used as the basis for the flight software for satellite data systems and instruments, but can be used on other embedded systems.

Introduction
12+
-------------
13+
The CFDP application (CF) is a core Flight System (cFS) application
14+
that is a plug in to the Core Flight Executive (cFE) component of the cFS.
1015

11-
The CF application is used for transmitting and receiving files. To transfer files using CFDP, the CF application must communicate with a CFDP compliant peer.
16+
CF 3.0 is a cFS application for providing CFDP (CCSDS File Delivery Protocol)
17+
services. Its primary function is to provide file receive and transmit
18+
functionality to this protocol. It works by mapping CFDP PDUs on and off cFS's
19+
software bus.
1220

13-
CF sends and receives file information and file-data in Protocol Data Units (PDUs) that are compliant with the CFDP standard protocol defined in the CCSDS 727.0-B-4 Blue Book. The PDUs are transferred to and from the CF application via CCSDS packets on the cFE's software bus middleware.
21+
The CF application is written in C and depends on the cFS Operating System
22+
Abstraction Layer (OSAL) and cFE components. There is additional CF application
23+
specific configuration information contained in the application user's guide.
24+
25+
Developer's guide information can be generated using Doxygen:
