Windows中使用RS 422串行通信的100 Hz数据. [英] 100 Hz data in Windows using RS 422 serial communication.

问题描述

我可以使用RS 422串行通信卡在Windows操作系统中发送100 Hz消息(每10毫秒发送一次消息，包含100字节的数据)吗?

我正在使用RS 422串行通信卡在Windows操作系统中发送100 Hz的100 Hz数据.我正在使用Windows计时器每10毫秒发送一次.但是数据在每个周期中都会丢失.我每个周期都会错过5到10个字节.有人可以在Windows中为这个问题提供任何解决方案吗?

Can I send a 100 Hz message (one message sent every 10 millisecond with 100 bytes of data) in WIndows Operating System using an RS 422 serial communication card without loss of even a single byte ?

I am sending a 100 Hz data with 100 bytes in Windows Operating System using a RS 422 serial communication card. I am using windows timer for sending it every 10 milliseconds. But data is lost in every cycle. I miss 5 to 10 bytes every cycle. Can anybody provide any solution in Windows for this problem ?

首先，Windows不是实时操作系统，因此您永远不会拥有确切的操作系统两个数据包之间的延迟时间为10毫秒(会有所增加).
其次，可以发送的数据量很大程度上取决于您在串行端口上设置的波特率.

First, Windows is not a real time operating system, so you will never have an exact delay of 10 msec between two packets (it will be a little bit more).
Second, the amount of data you can send depends a lot on the baudrate you set on your serial port.

不，您不能(作为用户空间开发人员，您不能).

No, you can''t (as user space developer you can''t).
