485Receive
- 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。

l298
- l298调 速 程 序 常规的接法是这样的,EnableA接PWM信号,Input1输入正反控制信号, Input2是Input1经过反相以后的信号。L298的电平是与TTL电路相兼容的,一般是超过2.5V就为高电平。假如Input1为高电平时电机正转,那么低电平时就是反转,PWM信号控制电机的转速。 _________________
