A Portable High-Speed Data Acquisition System Based on AVR and CPLD
Abstract— A portable storage-type data acquisition system based on ATmega162 (AVR) Micro Controller
Unit and CPLD is proposed by this research. The features of proposed system are low cost, high speed, high
reliability, portable, easy to implement. This paper describes the hardware circuit principle and the main
control program of the data acquisition system. According to analyze the characteristics and conversion
timing of MAX1308 ADC, the ADC circuit and its peripheral circuits are proposed. The entire system timing
state is controlled by the program of AVR and CPLD. The experimental result shows that the designed
system can achieve the original design requirement. The Multi-channel acquisition speed is greater than
10MB / s.
Index Terms— Multi-channel acquisition, Pipeline Storage, AVR, CPLD, NandFlash.
