摘要
本文提出了一种基于CPLD与MCU的多路高速数据采集系统的新方法。该系统利用AD7656和AD7864可以实现多通道同步采样或多通道异步采样,其中CPLD完成对A/D转换的逻辑控制,使用MCU对A/D转换数据进行处理。通过实际测试结果表明,所设计的基于CPLD与MCU的多通道数据采集系统,能够准确有效地进行A/D数据采集。
A new method of multi-channel and high speed data acquisition system based on the CPLD and MCU is proposed in this paper. AD7656 and AD7864 are used to realize multi channel synchronized sampling or asynchronized sampling. While the ADC is logically controlled by the CPLD, the converted data are processed by the MCU. The practical testing result indicated that the de-signed multi- channel data acquisition system based on the CPLD and MCU is able to efficiently complete the ADC in the practical applications.
