FPGA数字电子系统设计与开发实例导航的配套光盘资料
注明:这是我从某网站刚下载到一本电子书的配套光盘代码,以下是原楼主说的话,我在此借用。好书一本,非常值得下载,不下后悔。本着“读书是一种心态,分享是一种快乐。”的精神向大家推荐:《FPGA数字电子系统设计与开发实例导航》这本书是在我搜索FPGA-USB中,出现最多次数的一本电子书,正准备学学FPGA的USB通信,也下载到这本不错的电子书。简单看了一下,写得挺详细,FPGA常用的接口也就这几个:I2C、RS232、USB、VGA、MAC(以太网)、CON总线。书中,不仅对其原理进行了详细的介绍,还详细介绍了相关的硬件芯片,以及对应的电路,然后以实例工程的形式对其进行了实现。非常的
