Abstract
The utility model discloses an intelligent card reader which comprises the following components: a power module, a single chip microcomputer and a liquid crystal module which are connected sequentially. The power module is connected with the liquid crystal module. The single chip microcomputer is connected with a SD card, wherein C8051F020 is adopted as the single chip microcomputer. According to the intelligent card reader of the utility model, single chip microcomputer hardware SPI and SD card are adopted for establishing a stratum link. Furthermore the operation in FAT layer to the SD card by the single chip microcomputer through software is realized on this basis. The convenient and quick reading of data information on the SD card by the single chip microcomputer is realized. Furthermore the data information is displayed on the liquid crystal module.
Description
Technical field
The utility model belongs to electronic data and reads technical field, is specifically related to a kind of intelligent card reading.
Background technology
Intelligent SD card is an electron device commonly used now, its volume is little, memory space is big and be convenient for carrying, and is widely used in portable field of storage, usually computer and SD card what communicate by letter employing is the SD pattern, but most of single-chip microcomputers are not supported the SD pattern, so can't read the information of SD card.
Summary of the invention
The purpose of this utility model provides a kind of intelligent card reading, has solved the problem that existing single-chip microcomputer can't read the information of SD card.
The technical scheme that the utility model adopted is, a kind of intelligent card reading comprises the power module, single-chip microcomputer and the Liquid Crystal Module that connect successively, and power module also is connected with Liquid Crystal Module, and single-chip microcomputer is connected with the SD card.
Characteristics of the present utility model are that also single-chip microcomputer wherein adopts C8051F020.
The beneficial effects of the utility model are, adopt single-chip microcomputer hardware SPI and SD card to set up the stratum link, and realize that by software single-chip microcomputer to the operation that SD sticks into capable FAT aspect, realized that single-chip microcomputer conveniently reads the data message on the SD card, and be presented on the liquid crystal on this basis.
Description of drawings
Fig. 1 is the structural representation of the utility model intelligent card reading.
Among the figure, 1. single-chip microcomputer, 2. Liquid Crystal Module, 3. power module, 4.SD card.
