CH343PUSB转高速异步串口芯片,芯片提供了常用的MODEM联络信号,比如RTS/CTS,DTR/DSR等,可以方便为计算机扩展异步串口,在实际的使用中我们除了扩展计算机的串口功能,在工业上我们还会用到485总线,下面介绍一下CH343P与RS485总线芯片的连接。


CH343P的DTR信号与发送数据指示(TNOW)是复用的,DTR引脚在上电或复位时由内部配置为输入引脚,内部固件会判断DTR引脚的信号,如果输入为低电平就切换为TNOW功能,TNOW引脚在CH343P发送数据时变为高电平,在接收状态时为低电平,TNOW信号正好可以控制RS485收发器的收发切换。为保证在上电/复位时DTR引脚为低电平,要在这个引脚上接一个3~8KΩ的电阻,通常接一个4.7K的电阻就可以。


在电源上,为了保证TNOW的信号能与外部的RS485的信号电平相匹配,建议将VIO与RS485的电源接到一起,VIO支持的输入范围是1.8V~5V,这可以各种不同供电电压的485芯片通信。CH343P与RS485之间TNOW信号的连接如下图:
