UDI, the Uniform Driver Interface, is a well-documented interface between a driver module and the executing OS. It provides source portability across OSes and binary portability within a processor ABI. It also provides modern driver features like instance independence, high scalability, and physical location transparency. The Reference Source provides an initial implementation of UDI for Linux, SCO UnixWare, SCO OpenServer, and other OSes.
The Linux Driver and API for Datel PC-462 project aims to produce a Linux driver and API for the Datel PC-462 Data Acquisition Card/Power Supply. From correspondence with Datel, there is no other Linux driver/API for this board. This software will allow developers and engineers to write test software that runs on Linux and incorporates the Datel hardware.
OpenCT implements driver and middlerware for smart card readers. OpenCT drivers can be used via the ct-api interface, the ifdhandler interface, or its own interface/middleware. It implements drivers for several USB crypto tokens, USB smart card readers, serial smart card readers, and PCMCIA smart card readers.
