As title, please help! VB and single-chip microcomputer communication, single-chip microcomputer sends data to the VB

Communication protocol? The format of the data? VB receive and display the code?

VB program in this

 Private Sub Command1_Click () 
If MSComm1. PortOpen=False Then MSComm1. PortOpen=True: Shape1. FillColor=255 
End Sub 



Private Sub Command3_Click () 
If MSComm1. PortOpen=True Then 
MSComm1. The Output=Text1. Text 

End the If 
End Sub

Private Sub Timer1_Timer ()
If MSComm1. PortOpen=True And MSComm1. InBufferCount & lt;> 0 Then
Text3. Text=MSComm1. Input
Text2. Text=Text2. Text & amp; "" & amp; Text3. Text

End the If

End Sub

CodePudding user response:

It depends on single chip microcomputer to send what,

If it is a printable characters, try

 
Dim TMP As the Variant 

TMP=MSComm1. Input 
Text3. Text=StrConv (TMP, vbUnicode) 
Text2. Text=Text2. Text & amp; "" & amp; Text3. Text

If it's any binary number, try:

 Dim TMP As the Variant, I As an integer 

TMP=MSComm1. Input 
Text3="" 
For I=0 To Ubound (TMP) 
Text3=Text3 & amp; Right (" 0 "& amp; Hex (TMP), 2) 
Next I 
Text2. Text=Text2. Text & amp; "" & amp; Text3. Text

CodePudding user response:

Single chip microcomputer send is
If (P2_4==0)
{SBUF=ge;
while(! TI);
TI=0;
}

CodePudding user response:

Ge's value is what?

CodePudding user response:

0 x * *; * * this literally will do

CodePudding user response:

communication protocol?
Including baud rate, parity, etc., MSComm controls whether the attribute set of consistent,

the format of the data?
Text or binary mode? MSComm controls whether the attribute set of consistent,
How to cut between the field?
Illustrate the results of the data and what do you expect,

refer to 6th floor baidu_17335183 response:

0 x; * *; * * this will do casually

you must press any binary values to display,
Computer character encoding is specified, such as es "printable characters" code contains only part of the above 0 x20 "defined" number, what are the specific look even chosen word stock,
Here is 0 x00-0 XFF you obviously have a lot of printable characters, according to the latter method, data will be sent up to display in the form of hexadecimal string,

You here is 0 x00-0 XFF obviously have a lot of printable characters, you press the back of the method, the data will be sent up to display, in the form of hexadecimal string

I used the method, behind you is shown? - these types, I just want to put the data received in decimal display in the text box

CodePudding user response:

What is your SCM from the format of the data?
Binary or a decimal
