HI ALL,

yes, i've seen this website ... but as you can see it's sending command just data ...
what i mean is to use the ascii code

First you need to configure PIC UART to connect to PC serial port. Then using the MSComm ActivX control in VB you can send anything you want to your PIC board.

hello to you all,

first thanks alot for the reply,

let have example to understand that better , to create command button in the visual basic and lets say if i press this button it's gonna send the character '0' which is d'48'(ACSII CODE) to the pic first i've to configure the MScomm

i did that so far :

Option Explicit

Private Sub cboBaud_Click()

On Error GoTo BaudErr

If MSComm1.PortOpen Then
MSComm1.PortOpen = False
End If
MSComm1.Settings = cboBaud.Text & ",n,8,1"
MSComm1.PortOpen = True

BaudErr:

If Err <> 0 Then
MsgBox Error$(Err)
End If

End Sub

so now, the problem how i'm going to send the d'48' to the pic,

thanks

to write the character that you want to send, just make this:


mscomm1.output='0'

thats all you have to do

and for read the buffer
dim x as string
x=mscomm1.input

if you have more problems, go to msdn and look for mscomm control

i've question it this command mscomm1.output='0' going to send d'48' to the serail port or just character

it is the same, character 0 is equal decimal 48 or hexadecimal 30, just look into the ascii code!!.
