与单片机相比，用CPLD/FPGA器件更适合于直接对高速AD采样控制。本实验接口器件为ADC0809，根据ADC0809的工作时序使用CPLD产生该控制信号，CPLD启动AD转换后，得到的数据送至单片机并在PC机及数码管上显示AD转换结果。(Compared with the microcontroller, CPLD/FPGA devices more suitable for direct sampling control of high-speed AD. The interface of the experimental device for the ADC0809 ADC0809 Timing CPLD is used to generate the control signal, the CPLD to start the AD conversion, the data sent to the microcontroller and the AD conversion result on the PC and digital tube display)

说明：  “基于 ROM 的 LCD图片显示实验 ”中利用 FPGA 片上存储资源存储图片，并通过 LCD接口将图片显示到 LCD屏幕上。但是由于 FPGA 片上存储资源有限，只能存储分辨率较小的图片(In the experiment of LCD image display based on ROM, FPGA on-chip storage resources are used to store pictures, and the pictures are displayed on LCD screen through LCD interface. However, due to the limited on-chip memory resources of FPGA, it can only store images with smaller resolution)
