Below are links to the statically-generated documentation for the FX3 API and Firmware
The FX3 API manages all the complex USB transactions and implements all the necessary tools to begin capturing high-speed, high-performance data in custom applications. This .NET-compatible API, written in VB.NET and C#, includes data streaming features tailored to reliably capturing inertial sensor data at the maximum data rate.
The FX3 Firmware was designed with compatibility and flexibility in mind. The firmware attempts to follow the Cypress program workflow and relies on FX3 system threading, execution priority, and event flags to execute firmware subroutines and transmit sensor data. Custom vendor commands trigger subroutines embedded in the firmware that read and write SPI data, measure external pulses, generate clock signals, and manage board configuration. Several SPI streaming modes are implemented, which allow applications to communicate with nearly every device in the iSensor portfolio.
