Fairchild Semiconductor FIS1100 Evaluation Kit is a 6D MEMS Inertial Measurement Unit (IMU) with sensor fusion to specify system level orientation accuracy.
When using with the supplied XKF3 9D sensor fusion, the system features an accurate ±3º pitch and roll orientation and a ±5º yaw/heading typical specification. It incorporates a 3-axis gyroscope and a 3-axis accelerometer and can connect an external ±3-axis magnetometer through an I2C master, forming a complete 9DOF system.
The FIS1100 includes an advanced vector Digital Signal Processor (DSP) motion co-processor called the AttitudeEngine. The AttitudeEngine efficiently encodes high-frequency motion at high internal sampling rates, preserving full accuracy across any output data rate. This allows the application to utilize low Output Data Rates (ODR) or on-demand (host polling) and still acquire accurate 3D motion data.
The AttitudeEngine allows reducing the data processing and interrupt load on a host processor with no compromises in 3D motion tracking accuracy. The result is very low total system power in combination with high accuracy, which are essential to portable and battery powered applications.
The XKF3 sensor fusion library for ARM Cortex-M provides a sensor fusion solution based on Xsens more than 15 years of experience in the industrial and human movement motion tracking fields. The XKF3 sensor fusion algorithm is optimized for use with the FIS1100 AttitudeEngine to provide high accuracy orientation and high-pass 3D velocity outputs at very low processor utilization.
