The Software Libraries suite provides a unified and scalable software layer for controlling, configuring and acquiring data from CAEN instrumentation across digitizers, VME systems and power supplies. Modern libraries such as CAEN FELib introduce a high-level abstraction of firmware registers through parameter-based interfaces, simplifying the development of custom DAQ and control software while preserving access to advanced hardware features. These libraries are designed for integration into complex experimental frameworks, supporting multi-threaded applications, multi-board synchronization and high-throughput data acquisition pipelines.

Complementary low-level libraries, including CAENVMELib and the CAEN HV Wrapper, enable direct control of bridges, controllers and high-voltage systems through standardized C/C++ APIs. Together, these tools provide a consistent programming model across operating systems and hardware generations, facilitating the development of portable, maintainable and high-performance control and acquisition software for scientific instrumentation.

  • Unified software stack for digitizers, VME systems and power supplies with high-level parameter abstraction

  • Multi-language APIs (C/C++, Python, LabVIEW) for Windows, Linux and ARM platforms with open-source components

  • Scalable multi-board and multithread acquisition support for custom DAQ architectures

  • Low-level libraries for direct hardware control (VME bridges, controllers, HV systems) with consistent communication interfaces
