transfering data to UC00A

[kane]

hi..i'm currently having problem with transferring data to uc00A using visual basic programming...anyone hv any clue on how to do it?

UC00A will create a virtual com port in your computer. So what u need to do is to open that specific com port in order to transmit/receive data from it. To check the correct com port, just go to Control Panel > System > Device Manager. Look into the Ports (COM & LPT). You'll find a new com port listed inside there.

ohh..ok..i will try it..thx ya..

[kane]

erm..do u know how to access the com port in visual basic? it is a serial or parallel port? i am new to visual basic..

[sich]

It's serial port.
You will need to establish the port in your vb program.

CODE: SELECT_ALL_CODE

Dim WithEvents port As SerialPort = New System.IO.Ports.SerialPort("[color=#FF0000]COM1[/color]", 9600, Parity.None, 8, StopBits.One)

You may use the port like this...

CODE: SELECT_ALL_CODE

port.Open()
port.Write(txtSendText.Text & "!%")
port.Close()

MSDN has the full details about SerialPort Class. There're a lot of example available in the internet. Cytron also provides some .NET sample source code here:
1. SC16A
2. SD02B

thx ya...err the program that u write :

port.Write(txtSendText.Text & "!%")

txtSendText.Text, is it the text that i wanted to send to the port?

and what is "!%" ?

[sich]

It's just an example...
Yes. That function will send string through serial port. "!%" is another string placed behind "txtSendText.Text". It can be any characters though.
There're also WriteChar & WriteByte functions if not mistaken.
U may refer to msdn for the argument to be put inside the function or just trial-n-error.
