  • procedure senddata var i:integer commflg : Boolean begin commflg:=true for i:=1

    procedure senddata var i:integer commflg : Boolean begin commflg:=true for i:=1 to 8 do begin if not fcomm comml writecommdata(sendbutter,i) then begin Commflg=false break end end end (4) 接收数据 在编写基于串口的计算机工业测控时,通常需要由下位机向PC机发送数据以使PC机了解系统的测试数据或下位机的运行状态,并进而控制下位机的行为。利用Spcomm串口控件接收下位机发送的数据信息的示例代码如下: //事件驱动方式接收数据程序 procedure TForm1.CommlReceiveData(Sender:Tobject Buffer:Pointer bufferLength:Word) var receivedata:array of byte begin sleep(100) //等待100ms,保证接收到所有数据 move(buffef ,receivedata,bufferlength) //将接收缓存区中的数据转移到数组中 …… end (5) 关闭串口 在系统开发中,应注意在不使用串口时应及时关闭串口,释放系统资源,否则可能会影响系统的其它应用。关闭串口的代码如下: procedure TForm1.FormClose ( Sender TObj ect:var Action:TCIoseAction ) begin comml.StopComm end

  • What happens with your machine when you need to move away from the computer for 10 or more minutes?

    What happens with your machine when you need to move away from the computer for 10 or more minutes? How secure is your data? Can someone sit on your chair while you are at a coworkers office and play with your data? Maybe you need a computer locking tool that is small and easy to use yet powerful enough to make sure your machine is locked when you need to go out for a break.
