Integrating BS2p and VB

kuskowski

I·have·most of it integration working good but the only problem I'm having is reading the code coming from the stamp·into Visual Basic.· Does anyone have any examples of an easy way to accomplish this?

Thanks,

Justin

kuskowski,

Are you setting the DTRenable to False within VB?

START
PC --> Waiting to send commands
BS2 --> Waiting to receive commands
PC --> Send request for permission to transmit command sequence
BS2 --> Grant permission to send command sequence, await MainCommand
PC --> Send MainCommand
BS2 --> Acknowledge receiving MainCommand, await SubCommand
PC --> Send SubCommand
BS2 --> Acknowledge receiving SubCommand, process command sequence
...

This is what the code looks like in VB..

VB:

SerialPort1.Write("Sending_Command1") 
SerialPort1.Write(Command1) 

Try 'Request 2nd command 
   SerialPort1.Read(b, 0, 20) 

   If SerialPort1.BytesToRead <> 0 Then 
      MessageBox.Show("Got some data!") 
   End If 
   Catch ex As Exception 
End Try 

SerialPort1.Write("Send_Command2") 
SerialPort1.Write(Command2) 

Try 'Request 3nd command 
   SerialPort1.Read(b, 0, 20) 

   If SerialPort1.BytesToRead <> 0 Then 
      MessageBox.Show("Got some data!") 
   End If 
   Catch ex As Exception 
End Try 

SerialPort1.Write("Send_Command3") 
SerialPort1.Write(Command3)

Note, if you're writing to the 'programming port', aka "port 16" on the BS2, then everything will be 'echoed' back to your VB program by the BS2 hardware, THEN the BS2 response will be sent to you.

:SIDE NOTE:

I plan on going to BlueTooth, I have the AppMod Bluetooth and right now I am using port 0
