摘　　要：本文采用FPGA器件EP1C6T144C8芯片代替单片机控制A/D转换芯片ADC0809进行采样控制,整个设计用VHDL语言描述,在QuartusⅡ平台下进行软件编程实现正确的A/D转换的工作时序控制过程,并将采样数据从二进制转化成BCD码。本设计可用于高速应用领域和实时监控方面。By using FPGA device EP1C6T144C8 as the controller of AID converter ADO809 in this paper that take the place of MCU. The whole design is described in the VHDL. Carrying out the soft programming under the Quartus Ⅱ platform to realize the correct sequence controlling process of AID converter and change the Binary number into the BCD code. It can be widely used in high-speed application field and the real-time supervisory control aspect.
