| Abstract: | Based on micro - accelerometer, the commonly used MEMS inertial device, a design of data acquisition system with ARM and FPGA is introduced. The analog output signal of the micro - aecelerometer converted by A/D chip is processed and cached by FPGA. Then ARM receives FPGA＇s output data, also displays and storages them. How to realize the transmission control and data buffer of the data acquisition system with FPGA,as well as the interface design of A/D conversion chip and ARM with FPGA are given in detail. The collection, transmission,display and storage of the acceleration data are realized. The method can be configured flexibly and used versatility,so it can be easily transplanted to relevant device＇s data acquisition system. |
