| Abstract: | Collecting card of image and data based on parallel port protocol(EPP) can be applied to notebook PC and make data collecting equipments more portable.In this paper,EPP protocol was introduced and the logic of FIFO read/write operations and data read cycle of EPP protocol were realized with VHDL language.Meanwhile, hardware structure graph of data collecting card and the flow chart of display programme were given. |
