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

basic compiler for 8051

8051编译器 dos下 很小-8051 compiler under small dos

* 硬件结构： PA0-5对应６个ＬＥＤ数显管的位 ，PC0-7对应各ＬＥＤ数显管的段 ，PB4-7为键盘。 * 软件描述： 上电后，时钟从00.00.00（时/分/秒）自动走时，在走时状态时 ， 按PB4（设定 * 键）超过3秒可循环选择调整时间/工作参数 ，接着按PB5以确定选择的操作 ，进入调整操作后 ， * 按PB5选择欲调整参数，按PB6（增加键）完成调整参数操作 。按PB7，进入时控运行，PB1亮， * 再按PB7停止时控运行，回显走时。在定时到时，PB0点亮。- * Hardware architecture: PA0-5 corresponds 6 LED numbers to reveal the tube the position, PC0-7 corresponds each LED number to reveal the tube the section, PB4-7 is a keyboard. * Software description: After on electricity, clock from 00.00.00 (when/a minute/second) is in luck automatically, when is in luck the condition, according to PB4 (hypothesis * The key) surpasses for 3 seconds to be possible to circulate the choice time/operational parameter, then presses PB5 by to determine the choice the operation, after enters the adjustment operation * Wants according to the PB5 choice to adjust the parameter, (increases key) according to PB6 to complete the adjustment parameter operation.According to PB7, enters when controls the mov

将键盘发回的数据放到一个缓冲区里（数组），当按键结束后发生内部中断来处理所按的按键-returned to the keyboard data in a buffer (the array), when the button after internal interruption to processing by the key
