Jun 8, 2015 - To test that the sketch is working you can open the serial monitor: Arduino Visual Basic. Is connected to. ReceivedData is the data received on the selected COM port. As such the code can be made much better. – The COM port is left. Thank you for your guide and releasing the source code. I need your help for the complete source code that will communicate to the. The onComm event is used to receive data from serial port, and for more help follow the link. Most of all the electronic weighing scales are equiped with the RS232 monitor, and nn. Using MSCOMM32 control from VB6 like.

I'm using VB 2010.NET to read the serial port so I can make something more useful than simply writing out the data but initially that is all I am trying to do. I have taken some code I found called MAXIcom at and modified it to read simple output of 'Hello' plus an incrementing number. Rangrasiya serial song. The code works at 9600 baud but not at 115200. Twilight forest mod. The supplied code uses event handler for the reading (and hence in a separate thread). I also rewrote it to do everything in the same thread (read and update the text box) using a timer which I eventually set ticking at 1 ms.

It worked'ish but the GUI became unresponsive. In all cases the speed is not as fast as the Arduino serial output.

The program locks up. Various woes. At this time I'm not asking if someone could check my code I would just like to get my hands on some alternative to try.

Does anyone have some source or links to something that may be useful. Code: Imports System Imports System.IO.Ports Imports System.Threading Imports System.Threading.Thread Public Class Form1 Dim WithEvents COMport As New SerialPort Dim RXbyte As Byte Public Sub New() ' This call is required by the designer. InitializeComponent() ' Add any initialization after the InitializeComponent() call. COMport.PortName = 'COM8' COMport.BaudRate = 9600 COMport.Open() End Sub Private Sub Receiver(ByVal sender As Object, ByVal e As SerialDataReceivedEventArgs) Handles COMport.DataReceived RXbyte = COMport.ReadByte Me.Invoke(New MethodInvoker(AddressOf Display)) End Sub Private Sub Display() txtReceived.Clear() txtReceived.Text = (ChrW(RXbyte)) End Sub End Class and here is the Arduino code (util.h manages the printf support) and it speeds along on the Arduino serial output. The Arduino output is generating test data. The objective is to have a better tool than a simple print of values (eg a plotter or a visual representation) To get there I have to make it work!

Then I have to check its performance capabilities and envelop. I am obviously concerned about the performance/stability and my approach being wrong. Arduino manages the 'jamming' as does so I'd like to get my version working too. PaulS, what did you think the 'Hello' was for? More useful than the number counter!
