fm1702 13.56m rfid 读卡程序-fm1702 13.56m rfid reader program

51单片机开发的8道门出入记录控制板，具有RTC时钟功能，同时具有声光抱紧，能实时的记录被监控门的打开时间。本案例只有8路，但可以方便的扩展至32路。-51 MCU development of 8 door access control panel recorded with RTC clock function, both sound and light to hold fast, can be monitored real-time record of the time the door opened. This case is only 8-way, but can be easily extended to 32.

sst25vf040接口程序 可作为单片机与FPGA通信接口-sst25vf040 interface program can be used as communication interface MCU and FPGA

FM1702芯片开发板源码采用AT89C52单片机控制射频芯片1702可以用在水表电表等上面-FM1702 chip development board source control using AT89C52 1702 RF chip can use the meter to a meter above etc.

单片机红外通信程序，实现单片机字符发送与接收的功能，支持ASCII码字符液晶显示功能-Single-chip infrared communication procedures, realize Singlechip characters send and receive functions, support for ASCII code character liquid crystal display function

51系列单片机实验课程：串口 （通过计算机与试验箱相连，互相收发信息）-51 Series single-chip experimental curriculum: serial (through the computer and the chamber connected to each other to send and receive information)

液晶显示器以其微功耗、体积小、显示内容丰富、超薄轻巧的诸多优点，在袖珍式仪表和低功耗应用系统中得到越来越广泛的应用。 这里介绍的字符型液晶模块是一种用5x7点阵图形来显示字符的液晶显示器，根据显示的容量可以分为1行16个字、2行16个字、2行20个字等等，这里以常用的2行16个字的1602液晶模块来介绍它的编程方法。 -LCD display with its micro-power consumption, small size, display rich content, ultra-thin lightweight many advantages, in the pocket instrumentation and low-power applications are more and more widely. Here introduce the character LCD module is a 5x7 matrix used to display graphics characters liquid crystal display, according to show that the capacity of one line can be divided into 16 characters, 2 lines 16 characters, 2 lines 20 characters and so on, here commonly used 2 lines 16 characters LCD module to the 1602 introduction of its programming method.

按键扫描 51单片机加8279 8279通过74LS 138译码器扩展4×4键盘、6位显示器。 由3-8译码器对SL0～SL2译出键扫描线，由另一3-8译码器译出显示器的位扫描线，并采用了编码扫描方式。 为了防止出现重键现象，扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式，故8279的中断请求信号IRQ悬空未用。 -Scan button 82,798,279 plus 51 single-chip decoder 74LS 138 through the expansion of 4 × 4 keyboard, the display 6. From 3-8 decoder SL0 ~ SL2 translated to the key scanning line, by another 3-8 decoder translated display scan line, and uses code scanning. In order to prevent the emergence of the phenomenon of re-key, scan the output line does not take part in high level SL3 scan decoding keys. CPU on the 8279 surveillance using the query mode, the 8279 interrupt request signal IRQ left unused.
