在新的C＃2005 Expres中通过串行端口传输'char'数组 [英] Transmitting a 'char' array thru serial port in new C# 2005 Expres
问题描述
我试图在新的C＃2005中从串口发送一个6字节的char数组
Express：
com.Write（new string（new char [] {（char）34，（char）14，（char）192，（char）51，
（char）0，（char）0}，0,6））;
我从端口收到34,14,63,51,0,0因为我使用以下代码将Tx和Rx引脚相互连接
： br />
private void com_DataReceived（object sender，SerialDataReceivedEventArgs e）
{
bytes = com.BytesToRead;
if（bytes> = 6）
com.Read（buffer，0，bytes）;
}
难以理解的是：在这个数组中，如果我用127或
替换192以下任何数字，我会将数组恢复原状。任何超过127的数字都是
收到63.
关于其潜在原因的任何想法？

com.Write(new string(new char[] { (char)34, (char)14, (char)192, (char)51,
(char)0, (char)0 }, 0, 6));
I am receiving 34,14,63,51,0,0 from the port as I connected Tx and Rx pins
to each other by using the following code:
private void com_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
bytes = com.BytesToRead;
if (bytes >= 6)
com.Read(buffer, 0, bytes);
}
The hard thing to understand is: in this array if I replace 192 with 127 or
any number below I get the array back as it is. Any number above 127 is
received as 63.
Any ideas about the underlying reasons for this?

听起来像它使用ASCII编码 - 你用什么编码
想要它使用？

如果回复小组，请不要给我发邮件
It sounds like it''s using ASCII for its encoding - what encoding to you
want it to use?

63是'用于奇偶校验错误的默认字符，不确定你如何获得在同一端口上发送和接收数据的奇偶校验错误
$ b虽然$ b。如果你想从端口发送字节，它可能有助于将它们作为一个字节数组而不是字符串数组发送给它。

63 is the default character that''s used for parity errors, not sure how you
could a get a parity error sending and receiving data on the same port
though. If you want to send bytes out the port it may help to send them as
a byte array instead of as a string though.

一个其他的想法，我没试过这个，但是，你有端口数据库
设置为7？我认为这会有效地限制你到0-127。

One other thought, I have not tried this but, do you have the port databits
set to 7? I think that this would effectivly limit you to 0-127.
