针对中小企业的一个信息化应用方案，一本实用的方案。-For SMEs in an Information Technology Application Program

本作品采用Atmel公司的AT89C51单片机，以汇编语言为程序设计的基础，设计一个用四位数码管显示时、分的时钟。在实物图中，左边靠近电源的绿色发光二极管（长亮）是电源指示灯，表示的是5V稳定电源工作正常；单片机左下角红色发光二极管是秒灯，每闪烁一次表示时间走动一秒钟；按键正上方绿色发光二极管是设置灯，当时间正常走动时此时不亮，当第一次按下设置键（右键）时，此绿灯亮，同时秒时熄灭，且分钟的两位数码管出现闪烁，时间停止走动，进入校时状态，表示此时可以进行分钟的调整，当按一次加一键（左键）可实现分钟的加一功能，分钟以60分为极限，超出60分则返回数值0，从0再重新算起；如果再次按下设置键时，这时秒灯和设置灯仍旧保持熄灭和点亮状态，表示分钟的数码管停止闪烁，反过来表示小时的两位数码管则开始闪烁，此时可进行小时的调整，按加1键可实现小时的加1功能，小时调整以24为上限，同样超出24小时则从新回0；当第三次按下设置键时，数码管停止闪烁，设置灯熄灭，秒灯重新闪烁，时间以设定值计时。-err

所谓短信猫，其实是一种工业级级GSM MODEM，通过串口与计算机连接，可以通过AT 指令控制进行短信收发的设备。国内目前应用较多的短信猫，都是以SIEMENS 或WAVECOM 模块为核心组装而成的，与普通手机相比更为稳定高效。-The so-called SMS cat is a kind of industrial-level GSM MODEM, connected through the serial port and the computer can be carried out through the AT commands to control the device to send and receive text messages. At present the application of the domestic cat more messages are to WAVECOM module SIEMENS or assembled at the core, and more stable compared to the ordinary high-performance mobile phones.

LCD Driver datasheet The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of SPFD54126A adopts OP-AMP structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power consumption.
