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

本人以前做的一个DVD+TV 项目,51用做控制,含 NEC红外遥控接收和转发,VFD1632驱动,OSD 芯片M35055,NTSC高频头控制以及I2C 24C02的读写,因为以前所写,有些地方看起来有点乱,但功能模块OK,整个程序也是可以运行的,希望能给初用者有点参考-I used to do a TV DVD, 51 used as a control, with NEC infrared remote control and forwarding, VFD1632 drive, OSD M35055 chip, NTSC tuner control and I2C 24C02 read and write, because it was written in some places appear to be a little messy, but functional modules OK, the entire procedure can be run in hopes of giving users a bit early reference
