摘　　要：本设计利用FPGA控制DS1302时钟芯片实现数字时钟。FPGA芯片是系统的控制核心,按键通过FPGA的I/O口执行相应的操作,即对DS1302时钟芯片的数据进行配置,然后FPGA定时读取DS1302时钟芯片的数据,传到数码管中译码显示。在FPGA读取数据的过程中,整点时蜂鸣器会发出SOS的声音和LED灯闪烁,并有LCD液晶上闪现皮卡丘图像。The design is to use DS1302 clock chip to realize digital clock on FPGA.The FPGA chip is the control core of the system.The keys are operated through the I/O port of the FPGA,that is,the data of the DS1302 clock chip is to be configured.Then the data of the DS1302 clock chip is read by the FPGA regularly and transmitted to the digital tube for decoding and displaying.In the process of reading data by FPGA,the buzzer will emit SOS sound and LED lamp flashing at the whole point,and Pikachu images will be flashed on LCD liquid crystal.
