ROS搭配8051单芯片应用….

小弟想利用ROS的 Scheduler 功能命令ROS串口输出”字元”让外部的8051单芯片接收ROS串口解码来做简单的自动控制.
请教前辈有人知道该如何让ROS命令串口输出英文字元吗?(RS232的第3只脚 TXD)

:L ，这个……
大概要问mikrotik了，看他留了编程接口没有。

楼主的这个想法不错啊，通过单片机控制外围的设备

Sending text out over a serial port
From MikroTik Wiki
Sometimes there's a need to send out some (short) text over a serial port to control other devices.
As RouterOS doesn't (yet?) provide a native command to do that, you can work around with the following little script:

/interface ppp-client add name="scripttemp" port=serial0 modem-init="I am the string" null-modem=yes disabled=no
:delay 1
/interface ppp-client remove
The following assumptions were made:

We want to use serial port "serial0"
We have configured the serial port to match the other devices' setup (baud-rate etc.)
serial0 (or whatever port you use) is not used by RouterOS serial-console
The script sends the text configured as modem-init string out over the serial port when run.
So in the example above, it would send "I am the string" (without the quotes).

:victory:

哈,太感谢了,一直都没想到用PPP Client这部份.
真是一语点醒梦中人,谢谢.

lhn1324是个好同志。

嘿嘿 , 测试成功了, 可以命令 ROS 串口送出字元了,再来就只剩下单片机的部份啰.
再次感谢lhn1324兄台.
