U12 Software Installer Downloads - U12
Overview
The U12 Library is used for programming with the U12 device. Find example code in several languages below. If you can't find example code for a particular language, the user's guide is a good resource to get you started.
Notice: macOS 10.15.4+ are not supported for the U12. The U12 USB interface relies on Apple kernel extensions, which were deprecated in macOS 10.15.4.
