VS 2008 Serial Data To A Text Box?

Aug 21, 2010

I have a PIC program written in PicBASIC pro that sends out variables in word (ie 260, 458 etc). I would like to write a simple one form application that displays these variables in a box like this (just a mocked up image)In my search for VB code examples on how to use the serial port I came across one basic but functional example

Imports System.IO
Imports System.IO.Ports
Imports System.Net
Imports System.Data

[code]....

This is correct as there is only one variable that contains data at the moment (Temperatures(2) ), so the values are 0,0,261,0 for the first line. the increase in temperature was reflected in subsequent readings as it went up to 26.6C and then 26.8C.However I am now stumped... I don't know how I can adapt the code to brake the data up into the 4 variable and place them in to 4 different text boxes.

VS 2008 Serial Data - Make Sure The Correct Data Is Received?

Jun 28, 2009

I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.

My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected

eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>

VS 2008 Serial GUI Data Manipulation

Apr 26, 2010

I have been using Dick Grier's example to attempt to attempt to read data coming from a project.I first have to read 16 bytes for an RFID tag. I have that working and am able to extract the unique ID code and display it (cut out for length).The project samples voltage on an ADC and transmits 120 samples ranging from 0 to 255.I am attempting to buffer in the 120 samples, convert the scaled voltages (195 Vp or so (115% of Vnom)), and calculate Vrms.When I attempt to calculate and display the information, nothing is displayed.[code]

VS 2008 - Program In Vb To Serial In Data From My Microcontroller

May 18, 2010

I have written a program in vb to serial in data from my microcontroller and it is working good except for one thing. When I try to send the number 26 to vb it just reads a blank I dont know what is going on? The data that I am reading is being converted to int16, and I am using Encoding 28591 and have also tried Encoding 1252. I have also tried a new microcontroller with no success. I dont know if this is a VB problem or a microcontroller program problem.

Dim ReceiveBuffer As String
Dim portname1 As String = "Com5" ' Serial in through this port
Dim portspeed1 As Integer = 19200
Dim WithEvents COMPort As New System.IO.Ports.SerialPort

VS 2008 Get Data From USB UART, But Not USB-to-Serial Adaptor?

May 27, 2011

I have written a sketch for Arduino that sends serial data to my VB.Net app. Works great using the included USB port on the board. I need more distance, so I installed a MAX232. This is interesting. I get proper data in TeraTerm for both com ports (the Arduino USB comes up as a com port). I get proper data in my VB app from the Arduino USB (com) port. I get nothing from the MAX232 circuit on the other com port in my VB app. Why would both work in TeraTerm, but only the USB cable on the Arduino, not my MAX232 circuit in my application?

HSD 32 Bit Data Bus To Serial Converter Via A Microcontroller - Data Sniffer To Read The Data Bus (32Bit)

Sep 3, 2008

Im working on a HSD 32 bit data bus to serial converter via a microcontroller. Now first I want to make a sort of data sniffer to read the data bus (32Bit) .All on the controller side is working and the stream of bytes are coming in via RS232 as 4 bytes in HEX like FD,A5,45,8B . I already converted the bytes in Dec and ASCII to determine what is passed true the bus and how fast and stuff.. Now that is all correct and working very well if the LSB (least significant bit) of the 32 data bus is Data line 0 and the MSB (most significant bit) is Data line 31 but if that is not the case I need to invert the 32Bits (like as I would invert the connector on the bus) . How do I best do this using the 4 bytes I send from the micro controller.

Example:

(MSB) 01001000 01100101 01101100 01110000 (LSB)
HEX= 48 65 6C 70
DEC= 72,101,108,112
ASCII= H E L P

I need to invert it with a button to:

(MSB) 00001110 00110110 10100110 00010010 (LSB)
HEX= 0E 36 A6 12
DEC= 14,54,166,18
ASCII= (SO) 6 : (DC2)

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?

Serial Data - Split And Show Data?

Jun 25, 2009

I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can type commands into a text box and have set up a button that sends that text to the serial port. This text is displayed in a big text box as well as the feed back from the serial port (multirom audio controller).

Here is an example of what I send and receive to and from the controller;

I send *Z01STATUS (query's the Zone 1 status of the controller)I then receive the data from the controller #Z01PWRON,SRC4,VOL99 (This tells me Zone 1 is on, Source 4 is selected and the volume is at level 99 I can easily create buttons to turn the zones on and off and control the unit. My problem is I want to make things change on my form coresponding to the data received. ie I want to display the current volume of each zone and whether thetay are on or off etc. How do I get the individual bits of data from the data received. IE how do I get the VOL99 to show 99 in a text box?

IDE :: Can't Display Text During Serial Transmission

I am using this routine to send one line of text to a serial port.The text file is made of many lines. This code works except for TextBox1 line.I like to print * signs for every line sent to indicate the system is working.[code]The routine waits and pumps out all of the * signs after the transmission is completed.

1- How can I place one * per line of transmission in TextBox1?

2- Is there an easy way to add 15milisec of delay at end of each line?
