How to convert digital signal to hexadecimal string?

Hi!
My problem seemed to be very easy but I cannot find a simple solution. Namely, I have to make a simple project that acquires bits from a single digital line (not that it is important but I use one channel of a PXI 6552) and stores a certain number of bits (let’s say 1000 bits) from the channel in a txt file in hexadecimal format. I can convert it to a binary array of unsigned integers and make a loop that reads every 4 bits and calculate hexadecimal value but is it possible that there is no simpler way?!
Thank you!
Solved!
Go to Solution.

Thank you for your prompt reply! I understand that hexadecimal is just a format of presenting data but I have a problem to write digital data in that format to a txt file.
To make it easier for understanding and for testing purposes as well, I have made a test program that reads hexadecimal values from a txt file (the structure of this file is the structure I need to get at the end), transforms it in a digital stream as I get from the pxi 6552 (I had to change a bit the VI DTbl Binary U8 to Digital Stream.vi), and write it back to a txt file. This test program still needs some fixing to make input and output file exactly the same, but for the start output file is a txt file with hexadecimal values of my digital stream. I was wondering if there is a simpler solution for the while loop in this example.
I hope this example made it clearer a bit.

How to convert digital signal to analog

Hi..
I am using NI 9375 (DIO module) to read the output from flow sensor.
The output of the flow sensor is in the digital signal.(Boolean=True/False).
How can I convert the digital signal to the analog to get the reading of the flow sensor?
I had tried before to convert the digital signal to the frequency so that I can make the conversion from frequency to the flowsensor reading,
but it doesn't work.( I am referring to http://www.ni.com/white-paper/14549/en/ ).

FYI - If your flowmeter pulsing frequency is higher than 500Hz then you won't get reliable reading using your algorithm, and it will be very unreliable above 1kHz because fastest that loop runs is 1mS (1kHz). In that case you could tie the timed loop to a higher rate (hardware) clock source to go faster than 1mSec loop time. If no hardware then I think you can use high resolution timer (in LV2014, not sure if it was also available in previous version) and a regular while loop with algorithm modification for a faster timing.

How to convert digital array data into analog signal

i want help to convert digital data array into analog signal

We are implimenting real time audio trans-receiver. We have converted input audio data(analog form) into digital data. At the receiver side we received digital data which is in the form of digital data array.But we are unable to recover back our original input data. So please help us to sort out the problem.
Still no useful information. How was the data converted to digital in the first place? What conversion parameters did you use? As was said, you just need to do the math backwards to get it back into the analog.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to convert an array of Integers into String

So how can an array of integers be converted into a string?
As I do not have a javac with me now, I hope you guys could help.
Can it be done this way:
int [] value = new int[] {2,3,4,5,6,7}
String strValue = "";
for (i=0; i<value.length-1; i++)
strValue += value;

Instead of working with Strings, I would suggest you use a StringBuffer. It will improve memory utilization.
Like this:
int [] values = new int[] {2,3,4,5,6,7};
StringBuffer sbTmp = new StringBuffer();
final int size = values.length;
for (i = 0; i < size; i++) {
String intStr = Integer.toString(values);
sbTmp.append(intStr);
String strValues = sbTmp.toString();

How to convert a VISA Resource Name to String?

I would like to convert a VISA Resource Name (invalid reference) to string so I can open a session to a GPIB instrument.

You can typcast the VISA Resource Name, but I usually just treat it like a string. You can connect it directly to string indicators or to any VI that takes a string input. You can even search, concatenate and split it like a string. You can also feed strings into the VISA Resource Name inputs of the VISA functions.

How to convert hex into a string value

hei evryone!
can anyone please help me on how to convert a hex value into a string suppose.. Example i want to convert 4275646479 which is a hex value, into a string "BUDDY"? how will i do that???
Any suggestion, tutorial site would be appreciated?
Thx!

something like this will convert string to byte[]
e.g.
you want to convert following.
656667 => ABC
String toConvert = "656667";
byte[] returnVal = String2byteArr (toConvert );
String FinalStr = new String(returnVal);
public static byte[] String2byteArr(String Result)
byte[] byteRet = new byte[Result.length()/2];
int k=0;
for (int j=0; j<(Result.length()); j+=2)
try
Integer I = new Integer (0);
I = I.decode ("0x"+Result.substring(j, j+2));
int i = I.intValue ();
if (i > 127)
i = i - 256;
byteRet[k++] = new Integer(i).byteValue();
catch(Exception e)
System.err.println(e);
return byteRet;
}// String2byteArr
Hope this will help you, So that i can get 3$ (:-)

How do I convert analogue 5.1 surround sound into a digital signal? (Pioneer SE-DIR800C headphon

I understand that my SB Audigy 2 card will only output 5. sound from games through its 3 analogue connectors. How do I convert this analogue signal into a digital one? What hardware do I need to purchase?
I have read the thread on "Digital Connections, SPDIF and Dolby Digital Info", and also I've thoroughly read the "Creative Speaker Connectivity Guide".
The reason I ask is that I have just bought a pair of Pioneer SE-DIR800C Surround Sound headphones. This are supposedly fantastic for recreating surround sound on headphones because there is a clever little decoder box. They accept a DTS / Dolby Digital signal via the digital co-axial and optical inputs, and there is a single analogue input which only accepts stereo sound.
My XBox and PS2 will output true digital 5. sound via an optical cable and I am confident this will work perfectly with these headphones. I'm really looking forward to playing Halo in surround sound! But for gaming on my PC, I'll be limited to just an analogue stereo signal. Well, unless I can find some device that will convert my SoundBlaster's analogue 5. outputs into a digital signal, which I can then plug into the little decoder box for these headphones.
So, back to my question:
What hardware do I need to buy to convert an analogue 5. signal (via 6 x RCA or 3 x 3.5mm stereo ) into a true digital signal (via optical or co-axial SP/DIF)? Is it some type of headphone amplifier I need? If possible, please recommend makes & models of equipment.

Thanks stefan
OK, basically I have found 3 options for getting digital 5. out of a PC:
a) Creative DTS-60 (approx $90). This converts the SB's analogue into digital, but it's not available in the UK and it also introduces a noticeable 50ms sound delay. Also, who wants an extra box hanging out of their PC?
b) Buy a new sound card which has Dolby Digital Li've output. For example, ) BlueGears HDA X Mystique 7., or 2) Turtle Beach Montego DDL, or 3) Terratec Aureon 7. PCI (NOT the Space, FireWire or Uni'verse cards). I couldn't find the first two available in the UK so I have just ordered the Terratec card from Komplett.
c) Buy a new motherboard that has built-in Dolby Digital Li've output, for example the ABIT Fatalty AA8XE. Unfortunately my PC is only just over year old and I'm not quite ready to replace it.
I hope this info is useful for people. Maybe Creative will start making a card with DDL output too.Message Edited by NinjaHeretic on 2-22-2005 08:46 AM

How to convert a analog signal to digital signal

Hello,
How to convert an analog signal into digital signal such that every sample of analog signal corresponding to 1.2V will be represented as '1' in digital signal and other samples of analog signal(that are not 1.2v) will be represented(converted) as '0' in digital signal.
And how to display both wavefroms or signals in graph indicators.
Thanks.
Solved!
Go to Solution.

If you have 1000 samples, and you want to convert to digital, you are going to get 1000 digital values. Attached is what I mean.

How to convert an anlog signal having frequency range 40MHZ~800MHZ, to digital

I have an analog signal with frequency range 40MHZ~800MHZ. This is to be converted to Digital Signal and will be given to LPT port of the computer. From there this will be captured and compared with a pre-stored data. Please guide me to do this.

Hello;
To digitize an analog signal and have a good and accurate representation of the signal, the sampling frequency must be at least 8 times the highest frequency of the analog signal.That means, that you would need to digitize at 5 GHz frequency.
NI doesn't have a product that allows that high speed.
