The Yost Labs 3-Space™ v3 Application Programming Interfaces (APIs) are a series of functions, classes, and structure definitions designed to make writing applications that utilize the Yost Labs 3-Space™ v3 family of sensors fast and easy to support.

Currently, there is a 3-Space™ v3 Python 3.10 API beta available with all major features complete, and there is a 3-Space™ v3 C/C++ API currently in development. Binary libraries are planned for convenient integration into C and C++ projects, and the 3-Space™ v3 Python 3.10 API supports PyPI for convenient integration into Python 3.10+ projects via the pip module.

Source code for the 3-Space™ v3 APIs is also available.

Key Features

• Supports all members of the Yost Labs 3-Space™ v3 Sensor family (TSS-EM3 and variants, TSS-DL3 and variants, TSS-LX3)
• Provides access to all supported commands and settings available to the 3-Space™ v3 Sensor family in a human-readable ASCII format
• Designed to support all 3-Space™ v3 hardware with firmware versions 3.0 and higher, making forward compatibility easy for applications
• Native support for Python 3.10+ (currently in beta) and C/C++ (currently work-in-progress)
