由于普通LED点阵显示屏动态显示通常采用硬件扫描驱动，这在一些需要特殊显示的场合显得不够灵活。文中提出了一种利用PC机和单片机的通讯来实现显示屏灵活的动态显示和远程监控的设计方法，同时该方法还可以将显示内容在PC机上进行预览。-Because of the general dynamic display LED dot matrix display scan driver commonly used hardware, which in some occasions require special display appears not flexible enough. This paper presents a PC-use and single-chip communication to achieve a flexible dynamic screen display and remote monitoring and control design methods, while the method can also display the contents in the PC-on preview.

已经验证过的I2C，slave的IP，core，从一开源网站下载的，代码写的非常好，节省了FPGA的资源，比起以往的slave的CORE，这个CORE减少了寄存器的使用。-Has been verified I2C, slave of the IP, core, from an open source website, the code is written in a very good save FPGA resources than the previous slave of CORE, the CORE reduce the use of registers.
