HSD 32 Bit Data Bus To Serial Converter Via A Microcontroller - Data Sniffer To Read The Data Bus (32Bit)
Sep 3, 2008Im 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)

Read XML File - Read The Data From ?
Feb 13, 2010I have a fairly simple XML file that I just want to read the data from.
It has 3 levels, root, main section and items. There are no attributes. I want to go to the first main section by name, then read in all the items. The items all are named the same. I've seen this done before, so it should be ok. No writing will be done. Basically this is a static data file
File looks similar to the following:

That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)

Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

View 5 RepliesRead Data From Form
Jan 12, 2011I have a repetitive process requiring that I copy and paste data from text boxes in one program into another program for further processing. I'd like to automate this process using VB .NET. The application from which the data is gathered isn't mine, so I don't have ActiveX-like access to its controls.How would you write an application to gain access to a form from another application, to be able to find the controls on the form, and gather the values from them? Just experimenting, I've used the following code. This resulted in only the name of the form to which this code belongs. It didn't find the names of any other forms I have open, and I have a lot open to choose from.[code]
View 1 RepliesRead Data From Rs232?
Dec 4, 2009My program connects via the rs232 port to a pump and it managed to start the communication and sending data. But the problem arises when i try to read the return signal from the pump to pc. This is the piece of code i've used:
Code: Dim returnbyte(0) As Byte Dim ByteIndex As Integer = 0
Do While ClassSerialPort.BytesToRead <> 0 ReDim Preserve returnbyte(ByteIndex) returnbyte(ByteIndex) = ClassSerialPort.ReadByte() ByteIndex = ByteIndex + 1 Loop
[code]....
I obtain the following results:
Code:... 6 12 0 0 0 92 ...
From the manual i understand which byte to read. For e.g 6 = ACK. The problem is how to interpret the 4 bytes together in a string for e.g 0 0 0 92 means 9.2ml ?Is there any way to read the decimal point?

Read/write Some Data ?
Feb 13, 2012My first question has to do with the opening lines needed in a VB program in order to connect to Excel 2007 and read/write some data from/to it. I know the process only slightly and reading and writing to the cells is not my real concern for the moment. What I need to become familliar with are the lines like this:
CODE:
This is just one of the examples I have read through and to be honest I only follow this slightly. The trouble was that with each new article I read, people did this differently, not the variables on the left mind you, just that some left out lines, which I can see could be done based on circumstances. Still others said the Imports line was not needed....etc...and other loaded up at least 3 or four more Imports lines insisting all were needed.
I'm looking for some straight-forward advice on what is the minimum needed to access an existing Excel spreadhseet and to just read some of it's cells to variables in the code and then writed some data back to certain cells within the spreadsheet and then save and close it.
Also, please note that I am using VB 2010 Express. Why, because I'm a broke developer who spent most of last year out of work. I have a new contract assignment which is so far going well but will go even better if I can master this technique with VB.NET, not VBA. And all the docs I've read said that even though VB 2010 Express is a watered down version of VS, I should be able to do medium level tasks such as this with it.
RS-232 Only Able To Read In Data That Changes Constantly?
May 5, 2011I am working on a project that reads in data from a device. I am able to read in the constantly changing data only, i need to be able to read in the saved data that is in the device as well.
My question is if the data that is saved in a certain type and i only read try to read it in as text for example, will the saved data I am looking for not be displayed?
ex: im trying to read in text but my device has the data saved in hex, do i see anything or nothing?
idk if this helps or matters but the rs-232 connection is a null modem and im working with VB 2010
