ztex is a firmware Kit with a corresponding Driver API which is especially designed for the ZTEX Modules but which should work with all other EZ-USB based hardware. The Firmware Kit is written in C and assembled using a powerful macro processor. This allows you to specify all required settings using by a few commands. The necessary USB descriptors and the descriptor handling routines are generated automatically. The package runs under Linux and Windows (porting to other operating systems should be no problem). The Java driver API allows the development of platform-independent device drivers.
DeforaOS libc is an implementation of the Unix libc essential library. While originally intended to provide a POSIX compatibility layer to DeforaOS, it is also portable for Unix systems. Its small size and kernel abstraction make it suitable for embedded systems, exposing a single API regardless of the kernel used.
ZixFS is a simple embedded file storage based on a Zip file structure. It has been developed as an alternative to GridFS, but is still not on par with it. The main objective is to provide a powerful filesystem under a Windows 32-bit environment, with the capability of handling terabytes of data, which is not offered by GridFS. The original ZipStorer class library was developed Jaime Olivares.
