View 3 RepliesSend Data On Serial Port And Detecte It In Same Program?
Feb 24, 2011I 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.

Jul 8, 2011I 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

Send Data : String Through Serial Port?
Mar 11, 2010i 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.

Use A Textbox To Send Binary Data To Serial Port
Sep 1, 2009I 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()

Bridge Program The Time Between Appearance Of Cards Longer?
Apr 24, 2011I want in my bridge program the time between appearance of cards longer. Different suggestions can be found in the forum. I tried "System.Threading.Thread.Sleep(100)" resulting in the card appearing in half and after the delay the rest. Only the following code does as intended:
Dim Timer As DateTime = Now.AddMilliseconds(2000)
Do Until (Now > Timer)
Application.DoEvents()
Loop
I place this just for the code of the next card to be displayed. It is strange that the dim statement should be there. When I place it instead at the beginning of the program the code doesn't function anymore.I can live with that, however, in the forum some contributors write that this code is dangerous as it can slow down the machine considerably..Is that true or and/or only true for older versions of Visual Basic?
