磁卡读写器可以联接任何具有RS232串口的电脑或终端，用于读写磁卡或存折本上的磁条信息。磁卡读写器操作非常简单，具有读、写双重校验功能，读写卡均可一次性完成。磁卡读写器可广泛用于金融、邮电、交通、海关等各个领域，特别是银行系统的信用卡发行、磁卡和银行柜台的存折的磁条读写。 磁卡（magnetic card）是利用磁性载体记录了一些信息，用来标识身份或其它用途的卡片。视使用基材的不同，磁卡可分为 PET卡、 PVC卡和纸卡三种；视磁层构造的不同，又可分为磁条卡和全涂磁卡两种。

Over the past ten years there has been a revolution in the devel- opment and acceptance of mobile products. In that period, cel- lular telephony and consumer electronics have moved from the realm of science fiction to everyday reality. Much of that revolu- tion is unremarkable – we use wireless, in its broadest sense, for TV remote controls, car keyfobs, travel tickets and credit card transactions every day. At the same time, we have increased the number of mobile devices that we carry around with us. However, in many cases the design and function of these and other static products are still constrained by the wired connections that they use to transfer and share data.

You probably have heard all about what you can do with the Raspberry Pi. This credit- card sized computer can be plugged into your TV or any HDMI monitor to replace a typical computer. This little device is used in many computer projects, DIY electronics projects and even as a learning tool for kids who want to learn the basics of computer programming.

Identification is pervasive nowadays in daily life due to many complicated activities such as bank and library card reading, asset tracking, toll collecting, restricted access to sensitive data and procedures and target identification. This kind of task can be realized by passwords, bio- metric data such as fingerprints, barcode, optical character recognition, smart cards and radar. Radiofrequencyidentification(RFID)isatechniquetoidentifyobjectsbyusingradiosystems. It is a contactless, usually short distance, wireless data transmission and reception technique for identification of objects. An RFID system consists of two components: the tag (also called transponder) and the reader (also called interrogator).

FPGA读写SD卡读取BMP图片通过LCD显示例程实验 Verilog逻辑源码Quartus工程文件+文档说明,FPGA型号Cyclone4E系列中的EP4CE6F17C8，Quartus版本17.1。1 实验简介在前面的实验中我们练习了 SD 卡读写，VGA 视频显示等例程，本实验将 SD 卡里的 BMP 图片读出，写入到外部存储器，再通过 VGA、LCD 等显示。本实验如果通过液晶屏显示，需要有液晶屏模块。2 实验原理在前面的实验中我们在 VGA、LCD 上显示的是彩条，是 FPGA 内部产生的数据，本实验将彩条替换为 SD 内的 BMP 图片数据，但是 SD 卡读取速度远远不能满足显示速度的要求，只能先写入外部高速 RAM，再读出后给视频时序模块显示module top( input clk, input rst_n, input key1, output [5:0] seg_sel, output [7:0] seg_data, output vga_out_hs, //vga horizontal synchronization output vga_out_vs, //vga vertical synchronization output[4:0] vga_out_r, //vga red output[5:0] vga_out_g, //vga green output[4:0] vga_out_b, //vga blue output sd_ncs, //SD card chip select (SPI mode) output sd_dclk, //SD card clock output sd_mosi, //SD card controller data output input sd_miso, //SD card controller data input output sdram_clk, //sdram clock output sdram_cke, //sdram clock enable output sdram_cs_n, //sdram chip select output sdram_we_n, //sdram write enable output sdram_cas_n, //sdram column address strobe output sdram_ras_n, //sdram row address strobe output[1:0] sdram_dqm, //sdram data enable output[1:0] sdram_ba, //sdram bank address output[12:0] sdram_addr, //sdram address inout[15:0] sdram_dq //sdram data);parameter MEM_DATA_BITS = 16 ; //external memory user interface data widthparameter ADDR_BITS = 24
