摘要
针对现场可编程门阵列(FPGA)的特点,提出了一种使用超高速集成电路硬件描述语言(VHDL)有限状态机来实现串行外围设备接口(SPI)多通道采集和通过FIFO缓存采集数据存储至外部ROM的方法,设计了基于ADS7863的智能温度采集系统。实验结果表明:采用该方案能有效快速地完成折边机的智能温度数据采集与存储,验证了其可行性。
According to features of field programmable gate array（FPGA） , a new method was proposed for controlling serial peripheral interface（SPI） muti-channel A/D convener using very high speed integrated circuit hardware description language（VHDL） finite state machine and processing of FIFO cache and storing the sampling data in ROM. A temperature measurement and intelligent acquisition system based on ADS7863 was designed. Experiment result shows that method can control the temperature of folding machine quickly and effectively.
