97 law to enhance the classic Procedure
Ridge wavelet extraction
Modulus maximum for the wavelet edge detection
Small spectral analysis method mallat classic Procedure
this Procedure is simulated document management system disk space management, Disk Management, directory management (single-level directory) of a simulation program, as well as university computer courses on operating system design a case, we only reference
This is the Procedure for lab 1. This is a two-week lab. Prelab should be done BEFORE going to the lab session. In this lab the dielectric properties of materials and how these properties affect electric fields will be analized.
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) 接收數(shù)據(jù)
在編寫基于串口的計(jì)算機(jī)工業(yè)測(cè)控時(shí)，通常需要由下位機(jī)向PC機(jī)發(fā)送數(shù)據(jù)以使PC機(jī)了解系統(tǒng)的測(cè)試數(shù)據(jù)或下位機(jī)的運(yùn)行狀態(tài)，并進(jìn)而控制下位機(jī)的行為。利用Spcomm串口控件接收下位機(jī)發(fā)送的數(shù)據(jù)信息的示例代碼如下：
//事件驅(qū)動(dòng)方式接收數(shù)據(jù)程序
Procedure TForm1.CommlReceiveData(Sender:Tobject Buffer:Pointer bufferLength:Word)
var
receivedata:array of byte
begin
sleep(100) //等待100ms，保證接收到所有數(shù)據(jù)
move(buffef ,receivedata,bufferlength)
//將接收緩存區(qū)中的數(shù)據(jù)轉(zhuǎn)移到數(shù)組中
……
end
(5) 關(guān)閉串口
在系統(tǒng)開(kāi)發(fā)中，應(yīng)注意在不使用串口時(shí)應(yīng)及時(shí)關(guān)閉串口，釋放系統(tǒng)資源，否則可能會(huì)影響系統(tǒng)的其它應(yīng)用。關(guān)閉串口的代碼如下：
Procedure TForm1.FormClose ( Sender TObj ect:var Action:TCIoseAction )
begin
comml.StopComm
end
