VB 2003 - Handling Data - Transmitting Data From A Comm Device Via Serial Port

Nov 10, 2009

I'm currently working on a project where I am transmitting data from a comm device via the serial port and resorting the raw data (in binary) to its respective ascii values. The problem I'm facing is determining the most efficient method to accomplish my goal. Essentially, I have 68 bytes coming in, the first and second bytes represent the page and packet number and the data itself ranges from 3 to 64, the remaining for my checksum.

What I am needing to do is, grab 50 consecutive bytes per variable in my array, and that is where I'm confused. I have easily pulled my 3-64 bytes and stored that data to a string. I just don't know the most efficient method to accomplish my goal. Should I write directly to file all my data, as there are like 8 pages, of 128 packet data. [Code] I can capture the the first 50 by using a for-loop easily, but what would be the preferred method to track what data chunk I've taken? The more I think about it, I think I may just want to write to file, all my data, and then just take them back to back in 50 byte chunks. Is that the most efficient method?

Sending Hex Data Through Serial Port?

Mar 1, 2010

I am trying to send a command through my serial port to a external device. The format of the command frame is, more or less, like this:

'0x0A 0x03 0x20 0x00 Checksum'

What I've written on my code is just this:

VB code
num_dec = &HA + &H3 + &H20 + &H0
checksum = DecToHex(num_dec) '2D
data=&HA & &H3 & &H20 & &H0
SerialPort_RFID.Write(data & checksum)

The problem is that when I stop the program on the Serial...Write line, I see that the data I sent is on integer format instead of Hex format.

Serial Port Data Monitoring?

Jun 4, 2012

I've searched in the forum thread for my needs, and I couldn't find any. So here is my problem. I need to monitor the data passing trough serial communication, between local serial port and some device with an application written in vb.netThe idea is to see the data without opening the port.For example I want to start the program, choose the serial port that I want to monitor, and then to start some other application that opens the serial port, and start to send data. Another device "answers", and I want to see the the sent and received data from the first program, and the process that opens the port.I thought that I can use the serial port event "DataReceived", but actually nothing happens. I think my approach is wrong. CHere is my code:

Imports System.IO
Public Class Form2
Private WithEvents sp As Ports.SerialPort

Using Chr$ To Send Data To The Serial Port?

Feb 18, 2011

I used this code in the pass with VB6 to send hex data over the serial port to a microcontroller.

MSComm1.Output = "C"
Send command ID
MSComm1.Output = Chr$("1") Send Command Parameter
MSComm1.Output = Chr$(CStr(240)) Send CR

I need to convert the code using VB2010, but Chr$ is not available, and anything I tried will not send the actual ascii code character......

Close Serial Port After Data Received?

Feb 22, 2009

I have the following code that listens to a serial port and writes the incoming data to a listview control (the serial data are a delimited string taht arrives once per second that I parse into separate listview subitems). I would like to be able to close/disconnect the serial port once a specific value in the incoming string is detected. For example, in this case one of the columns of data in the incoming string represents depth, I would like to close the serial port when the depth falls below a given number. I have tried the code below, but my program crashes on the SerialPort.CLose method.

dim m_strOBS() as string
Private Sub SerialPort_OBS_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) _

Displaying Serial Port Data In A TextBox?

Apr 12, 2009

I can read data from the serial port (GPS receiver). Its just 2 lines of data every 0.5 seconds. Whats the best method to read the data and display it in a TextBox?
If I use:

DLdate = SerialPort1.Readline()

Then I don't get the new line character, and it just over writes on just one line of the TextBox.

Also, should I time the grab of data, or is there a better way? Should I create a buffer, and when the buffer is full then do a write?
