Open Source Embedded Systems Software

Alt-F provides a free and open source alternative firmware for the DLINK DNS-320/320L/321/323/325/327L and DNR-322L. Alt-F has Samba and NFS; supports ext2/3/4, VFAT, NTFS, BTRFS; RAID 0, 1, 5 (with external USB disk) and JBOD; supports up to 8TB disks; rsync, ftp, sftp, ftps, ssh, lpd, DNS and DHCP servers, DDNS, fan and leds control, clean power up and down... and more. Alt-F also has a set of comprehensive administering web pages, you don't need to use the command line to configure it. Besides the built-in software, Alt-F also supports additional packages on disk, including ffp and Entware packages, that you can install, update and uninstall using the administering web pages Alt-F is being developed and tested on a DNS-323-rev-A1/B1, a DNS325-rev-A1, a DNS-320L-rev-A1 and on a DNS-327L-rev-A1 hardware boards. Other models and boards are said to work. Support Forum: http://groups.google.com/group/alt-f Homepage: http://sites.google.com/site/altfirmware

This project is about using a SD-card together with an ATMEL ATmega32 microcontroller as mass storage medium. It implements the interface to the SD-card, a simplified FAT16 filesystem and a sample application: a data logger.

WSNFuse provides an abstraction layer for wireless sensor networks, allowing to expose one or many WSNs by means of different access technologies(e.g.: filesystem, JMS, RMI, Smart-Spaces, etc.).Its plugin-based architecture allow users to develop and adopt thei own plugins and configure WSN fuse to better suit their needs. This project has been partially supported by the CHIRON EU research project co-financed by the artemis joint undertaking (http://www.chiron-project.eu/) .

Simple, fast implementation of LZW (Lempel–Ziv–Welch) data compression algorithm in C. - Console encoder/decoder tools - OS independent - Could be used in embedded projects - Works with raw code-stream LZW features: - Hardcoded dictionary size - Variable code size - Code search is performed by hash table and embedded in dictionary linked lists (encoder) - No dynamic memory allocation
