I am trying to send and receive data through a USB port on my computer to an external microcontroller.

I built most of the code using the "serial class" but then i read that this would not work with a USB port.

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......

Send And Receive Data From A Serial Port?

Jul 8, 2011

I have created a program to send and receive data from a serial port, some of the data needs to be stored in certain strings for a export to excel. However the data takes while to to send be sent back. So in order to get the right information in the right strings I have to put pauses in my code. I have added a timer to my form:

On my timer's tick event I have the following code:

Public Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
iTick = iTick + 1
End Sub

Send Data : String Through Serial Port?

Mar 11, 2010

i knew Serial ports are a type of computer interface that complies with the RS-232 standard. They are 9-pin connectors that relay information, incoming or outgoing, one byte at a time. Each byte is broken up into a series of eight bits, hence the term serial port.And I want to write a program chatting through Serial Port.

Send Data On Serial Port And Detecte It In Same Program?

Feb 24, 2011

I am supposed to make a software for data logging via serial port but the hardware is expected to be delayed and iam required to continue with the programming of the software. What i need is that by some mechanism i want to send data on serial port (COM port) and after delay of some mili seconds i want to detect that data. I actually want to do this because i want to create environment like my software i intercepting COM port and on receiving data it captures the data values on port and record them to database. I have done most the work, the only thing left which i want is as above how i will send data on COM port (this was to actually to be done by hardware) and detect it in my program (same program from which data was sent). Please guide from where should i start.

Use A Textbox To Send Binary Data To Serial Port

Sep 1, 2009

I am currently sending data via a serial port to an AVR microcontroller. I've tried searching the forums here first but haven't found any posts that specifically deal with what I'm trying to do. Here's some additional information that might help before proceeding:

Sendbox = textbox
ReceiveBox = listbox
ReceiveChk = checkbox

I currently have it setup so I enter hex data in Sendbox, click the button, it sends the data to the AVR micro via the serial port, which gets repeated back through the serial port and receives the hex data in the ReceiveBox. I want to be able to setup something similar so I am able to input data into a textbox as binary and have it sent to the AVR that way.

I realize it will send the same data whether I enter it in hex or binary form. I just want the option of being able to send it in either form.

Below is my code.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SendButton.Click
SerialPort1.Open()

[Code]....

Send A Control String From .NET To A Serial Port?

Aug 5, 2010

I am trying to send a control string from VB.NET to a serial port. I am using a pololu trex jr. on the receiving end of the serial port. I have attached a copy of my current code which compiles without errors, but fails to send data. I can tell that it is not sending data because I have a light on the control board connected to the port and it normally blinks when data is received. The program that came with the board drives it perfectly but does not serve the purpose I need it to. I am open to any suggestions as I eventually plan to write a class to contain the control routines.

Send String Through Serial Port To Arudino?

Apr 18, 2012

im very new to visual basic. as in i just started 2 days ago. Currently i have a little program written up that has a couple of radio buttons and then a submit button. when you select a radio button and click the submit button, a little message box with pop up and say "you selected such and such"

Well now im trying to make something that will send a string to arduino through the usb cable. Basically it will use the same set up as stated above but instead of a pop up message it will just send the string through the port. for example Radiobutton1 - when selected and submit button pressed will send "1" (no quotes) through the serial port Radiobutton2 - when select and submitted will send "1" and then maybe "3"

and so on and so. Some radio buttons will only send 1 string through them and some may send multiple. Now, i dont need help with arduino, i have that already set up to wait for the strings to come through the com port. just need to figure out how to do it in VB.

Communications :: Send 8-10 Character Strings From The PC Serial Port?

Dec 1, 2011

I have quite a bit of VB6 experience but now am trying to create my first VB.Net project. The project is very simple - it just needs to send 8-10 character strings from the PC serial port. The problem I'm seeing is that VB.Net is always sending out a 0x0A character after each 'WriteLine' call. Using VB6 it was necessary to manually send out any End Of Line characters. My application requires that no extra EOL characters be sent after the string.

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?

Data Not Going To Serial Port As One Data String?

May 25, 2009

I have to send the user-input data to the serial port. From the serial port the Modbus controller reads the data in Modbus/RTU mode.Now consider the following:Private WithEvents sp as serialport Now when I send sp.Write "192" to the serial port, I was that the complete data go as one data packet. Instead what I find that when this data is sent to a hardware controller, I find that the serial port first transmits 1, then 9 and then 2. Because of this my modbus does not recognize this data and throws and error. I tried sending "12" and again i find that it goes as "1" and then "2". Is there any way to send the data as one data packet so that my modbus can read "192" as one data packet value and not as 3 data packets of 1, 9, and 2?
