摘要
针对单片机端口少的问题,应用FPGA对单片机进行端口扩展。FPGA端口数量巨大,片上资源丰富,可以方便灵活的对单片机端口进行各种形式的扩展。而且FPGA的再开发能力很强,可以根据实际应用的需要,和单片组成更加强大的系统。
FPGA is used to expand the singlechip I/O port because singlechip has few ports.FPGA can expand the singlechip port flexibly for the large amount of ports and the rich onchip resource.With singlechip FPGA can make a more powerful system according to practical application because of its re-developed function.
