用 AT89C51、LED 数码管、按键、二极管等部分构成，能实现时钟日历的功能：能进行时、分的显示。也具有时钟，定时时间的设定，实现三路开关定时输出等功能。-With AT89C51, LED digital tubes, buttons, diodes and other components, to achieve clock calendar function: to carry out, the sub-display. Also has a clock, timer time setting, the realization of three-way开关定时output functions.

关于单片机（51系列）通过GPRS模块和上位机进行通信-on SCM (51) GPRS modules and PC communication

这是一个单片机开发的包，其中有很多资料，是我搜罗出来的，请大家-This is the development of a single-chip package, in which there is a lot of information out of my collection, please take a look at U.S.

采用反正法扫描方法对4X4矩阵式按键进行扫描，判断是哪个按键按下。-Scanning method used in any case law on the 4X4 keypad matrix scan to determine which keys are pressed.

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.

单片机点对点通信，分为主机部分和从机部分。-Single-chip point-to-point communications, the host is divided into parts and parts from the machine.
