61505LCD的单片机驱动程序，此程序已在KEIL上调试成功-61505LCD microcontroller drivers, this procedure has been successful in KEIL debug

RS-485接口具有较强的抗干扰性，数据传输的距离较远，在一些应用中常常需要把RS-232标准的信号转换为RS-485的标准信号进传输。图中所示电路允许数据在RS-232/RS-485这两个不兼容的串行数据接口间传递。传输速度为480波特时，传输距离可达1750米。图中双RS-232收发器IC1将主机(PC)输出的RS-232电平转换为TTL电平，驱动高速RS-485收发器IC2 的输入，倒相器使IC2、IC3在受到起始位时被激活。-RS-485 trying to lay all the thoroughly bleed at the nose picking up the birthday 扰 fern cavity 强 ， Chu Huai basin cavity beat escapement for the birthday candle远Now ， Which instance, using Beckmannia中

m25p64是AT退出的一款大容量flash存储器，8Mbyte.串行通信方式，极大的节省了硬件资源。-64Mbit of flash memory.page program(up 256 byte)in 1.4ms.sector erase (512Kbit)

里面给出了ATmega103单片机编程的C语言实例程序，是学习参考的好资料。-ATmega103 single-chip inside gives the C programming language examples of procedures, is to learn from a good reference information.

动力环境监控系统，它是一个有十分价值的系统，现拿出来供大家参考，学习。可不能用于他用，后果自负。- The power environment supervisory system, it is has extremely the value system, presently puts out for everybody reference, the study. But cannot use in he to use, the consequence is proud.
