Usage of SPI interface in applications with MEMS components

Abstract

The paper deals with description of accelerometer and gyroscope work. The application is designed for communication testing with master system. Testing application uses communication of microcontroller and digital gyroscopes and cooperates with LCD touch screen through USB bus. Application is created for property gyroscopes testing, data acquisition and its other processing to implement these components in inertial systems. This contribution describes method of data transfer from MEMS component to PC, design and realization of communication between tri-axis gyroscope system and computer. One of contribution chapters is dealing with design of measuring chain and its technical support. The following part describes application, which was created at Control Web 5 environment. The application provides monitoring of actual values from particular axis of gyroscopes.
