基于ATMEGA48的线阵CCD数据采集系统

A data acquisition system for linear array CCD based on ATMEGA48

文章介绍了一种基于单片机ATMEGA48的CCD数据采集系统。系统采用两片ATMEGA48来产生CCD所需要的驱动脉冲以及控制数据的采集等。使用先进先出存储器IDT7204解决了高速的A/D转换和慢速的数据读取之间的矛盾。电路简单,易于实现。

A kind of CCD data acquisition system based on ATMEGA48 is introduced. Two chips of ATMEGA48 are used to produce the driving pulses needed by CCD and control the data acquisition. The FIFO （first in and first out） memory chip IDT7204 is adopted to resolve the problem between the high speed transferring and the low speed data reading. The whole circuit is simple and easy to realize.
