这是一本关于VHDL编程的书籍,网上突然发现的,相信对相关人员会有所用途....

Ａ８２５５的ｖｈｄｌ源代码，比较简单的一个-Vhdl source code of A8255

说明：  spi通用串行总线，4线控制，可读写操作(SPI universal serial bus, 4-wire control, readable and writable operation)

用VHDL实现自动售货机，可供毕业设计参考。可以输入硬币和纸币，硬币的识别范围是5角和1 元的硬币，纸币的识别范围是1 元、5 元，10 元，20元，50元，100元。可以连续多次投入钱币。可以选择的商品种类有16种，价格分别为1-16元，顾客可以通过输入商品的编号来实现商品的选择。 即有一个小键盘（0-9按键）来完成，比如输入15时要先输入1，再输入5。顾客选择完商品后，可以选择需要的数量。每次可以选择最多三个商品。然后显示出所需金额和已投币总币值。在投币期间，顾客可以按取消键取消本次操作，钱币自动退出。
