如何在c＃中延迟串口写入1秒 [英] How to delay the serial port write for 1second in c#

问题描述

在我的代码中，我必须处理串口写入，应该延迟1秒钟。

我的代码如下。

  while （bytesRd <  byteExpctd）
 {
 
 bytesRd + = serialPort.Read（Req，bytesRd，byteExpctd  -  bytesRd）; 
  //   serialPort.ReadTimeout = 80;  
} 
 byteExpctd =（ int ）Req [ 1 ]; 
  while （bytesRd <  byteExpctd）
 {
 
 bytesRd + = serialPort.Read（Req，bytesRd，byteExpctd  -  bytesRd）; 
 
} 
 
  if （Req [ 0  ] == 0x14&& Req [ 0 ] == 0x06）
 {
 AckMsg [ 0 ] = 0x0B; 
 AckMsg [ 1 ] = 0x06; 
 AckMsg [ 2 ] = 0xA4; 
 AckMsg [ 3 ] = CheckSum（AckMsg）; 
 serialPort.Write（AckMsg， 0 ， 5 ）; 
} 
 其他 
 {
  //  < span class =code-comment>某事的代码 
} 
 Thread.sleep（ 1000 ）; 
 RsltMsg [ 0 ] = 0x9F; 
 RsltMsg [ 1 ] = 0x05; 
 RsltMsg [ 2 ] = 0x19; 
 RsltMsg [ 3 ] = CheckSum（RsltMsg）; 
 serialPort.Write（RsltMsg， 0 ， 3 ）; 

如何在c＃中延迟串口写入1秒钟？我必须在第一次和第二次写入之间引入1分钟的延迟。我试过Thread.Sleep（），但它没有做任何改变。是否有任何替代解决方案来引入1分钟的延迟。我使用的自定义波特率为10,4K。请帮助。

解决方案

Thread.Sleep（1000）; 在这里应该可以正常工作。试一下，看看它是怎么回事。 Thread.Sleep（1000 * 60）;



否则你可以查看计时器。

Hi,
In my code i have to handle the serial port write, which should be delayed for 1 second.
My code is as follows.

while (bytesRd < byteExpctd)
               {

                   bytesRd += serialPort.Read(Req, bytesRd, byteExpctd - bytesRd);
                   //serialPort.ReadTimeout = 80;
               }
               byteExpctd = (int)Req[1];
               while (bytesRd < byteExpctd)
               {

                   bytesRd += serialPort.Read(Req, bytesRd, byteExpctd - bytesRd);

               }

               if (Req[0] == 0x14 && Req[0] == 0x06)
               {
                   AckMsg[0] = 0x0B;
                   AckMsg[1] = 0x06;
                   AckMsg[2] = 0xA4;
                   AckMsg[3] = CheckSum(AckMsg);
                   serialPort.Write(AckMsg, 0, 5);
               }
               else
               {
                  // code for something
               }
               Thread.sleep(1000);
               RsltMsg[0] = 0x9F;
               RsltMsg[1] = 0x05;
               RsltMsg[2] = 0x19;
               RsltMsg[3] = CheckSum(RsltMsg);
               serialPort.Write(RsltMsg, 0, 3);

How to delay the serial port write for 1 second in c#? I have to introduce a delay of 1 minute between the first and second write. I tried with Thread.Sleep(), but it doesn't make any change. Is there any alternate solution to introduce the delay of 1 minute. I am using custom baud rate of 10,4K. Please help.

解决方案

Thread.Sleep(1000); should work fine here. Try a minute and see how it goes. Thread.Sleep(1000 * 60);

Otherwise you could check out timers.
