During the design process, first of each part to write a simple control program, but as a comprehensive program design on the bottom of the later procedure. The system besides can realize the input/output experiment, LED digital display, buzzer sounds tube experiments, the frequency of experiment, experiment of basic experimental function can derive keying lamp, veter, priority encoder and timing clocks complex experiments. After completion of the system can already compiled code directly into target users on the boards, but not CPLD chip to remove from PCB CPLD chip. Download directly after commissioning, debugging due to frequent inserted to chip and remove chip board inconvenience, The multifunctional system is relatively low cost and can be used for students to learn autonomously EDA. The design is made by a team member and me.In this article mainly finish 5 modular circuit,such as Beep modular,the nixie dis
