Software Development

The USBStem has a BrainStem™ 2.0 kernel (internal OS) allowing the modules to operate as a host-driven slave device and/or run reflexive actions simultaneously. All BrainStem™ USB 1.0 modules can be networked with other BrainStem™ modules across the I2C bus at speeds up to 1Mbit.

A high level C++ software interface is supported for high level software development. BrainStem™ USBStem modules are supported on Windows, Mac OS X (10.7+) and Linux with 32 bit and 64 bit drivers.
