The embedded file system

emFile is a fail-safe file system for embedded systems and applications optimized for minimum memory consumption in RAM and ROM, for high speed, and for versatility.

The emFTP - FTP server is an optional extension which adds the FTP protocol to the stack. FTP stands for File Transfer Protocol. It is the basic mechanism for moving files between machines over TCP/IP based networks such as the Internet. FTP is a client/server protocol, meaning that one machine, the client, initiates a file transfer by contacting another machine, the server and making requests. The server must be operating before the client initiates his requests. Generally a client communicates with one server at a time, while most servers are designed to work with multiple simultaneous clients.

emLib—AES, DES, CRC, ECC
emLib is a collection of software modules such as, cryptographic modules and data integrity checks for different purposes. It includes AES and DES encryption as well as CRC and ECC.

A common challenge for manufacturers of embedded systems is to guarantee a system's firmware can be updated in the easiest way, even under adverse conditions. To replace bugged code in the field or to enhance the features of deployed systems, SEGGER provides the ideal solution: emLoad, the bootloader for firmware updates.

Modbus Software

emModbus, SEGGER's implementation of the Modbus protocol, supports communication via UART (ASCII, RTU), Ethernet (Modbus/TCP and Modbus/UDP), and is capable to communicate with any Modbus compliant device. 

• Supports ASCII, RTU and Modbus/TCP (and UDP) protocol
• Sample applications for all protocols included
• Kernel abstraction layer: can be used with or without any RTOS
• Modbus/TCP can be used with standard socket interface and any TCP/IP stack
