The STSW-ST25RU-SDK library is a comprehensive middleware software stack written in ANSI C programming language, which helps users build RAIN® RFID-enabled applications for reader devices based on the ST25RU3993 reader IC.

A complete demonstration source code is included in this software package to provide examples on how to use the ST UHF library for Windows® and Linux® platforms.

The software stack is ANSI C- and POSIX-compliant and enables fast and straightforward porting to other operating systems and/or toolchains.
