The App name, IMU, stands for Inertial Measurement Unit, and the name is indicative of the basic inertial measurement unit functionality provided by this APP. The IMU App signal processing chain consists of high-speed sampling of the 9-DOF sensor cluster (accelerometers, rate sensors, and magnetometers), programmable low-pass filters, and the execution of built-in calibration models.
Additionally any configuration parameters settings such as axes rotation are applied to the IMU data. The 200Hz IMU data is continuously being maintained inside the IMU APP, and is Digital IMU data is output over the UART port at a selectable fixed rate (200, 100, 50, 25, 20, 10, 5 or 2 Hz). The digital IMU data is available in one of several measurement packet formats including Scaled Sensor Data (‘z1’ Packet).
