I often require to interpret the file with hex numbers(may be called hex dump). Because I read the memory from the micro-controller and need to understand it, I thought, Neo-Hex Editor will help. But I found that Neo Hex Editor can open Intex-Hex Format, Motorola Hex format,Exe file, Image file etc.
But my file is series of hex numbers:
'0x0', '0x0', '0x6', '0x0', '0x78', '0x56', '0x34', '0x12', '0x5', '0x0', '0x1'........
I want to open such file in Neo Hex Editor, where I can see the address location of particular number. Its character equivalent on the right etc.
Please let me know, if I need to arrange my hex file in proper format.
Thanks.
You can try this:
Open the file in excel as a CSV file.
Transpose the row to a column
Remove all the apostrophes.
Remove all the 0x's.
Use this formula =char(A1)
It will look something like this (not all values are valid characters)
0 #VALUE!
0 #VALUE!
6
0 #VALUE!
78 N
56 8
34 "
12
5
0 #VALUE!

I'm using Hex Workshop and I needed to edit numerous data so I selected a range of HEX values and copied it to Notepad++.
I edited the values and now I need to copy it back to HEX Workshop but it seems to be a little problem. When I just CTR+C, I can't paste in HEX Workshop.
I tried using the Insert function but it will just convert everything from the TXT file to HEX. That's not what I want - the content on TXt file is already in HEX. I just want to simply paste and overwrite the values in HEX Workshop.
Same as I would if I edited it manually byte by byte in HEX editor but I just want to copy these values form TXT and paste it in HEX.
I know I can edit in HEX editor ofc, but I needed to do some other stuff around these HEX values.
I use the open source tool Be.HexEditor for pasting text hex values into a file as hex:
Copy hex code to the clipboard
Open target file to insert hex code
Move the cursor to the the desired position to insert hex
Click Edit > Paste Hex
Save
Nevermind. Hex Editor Neo did the trick.

I make a project for school : it's a boxing captor made with the Arduino nano 33 ble sense. I only use the accelerometer and gyroscope include on the card. I want to know the acceleration of the boxer's hit in order to deduce the hit power of the boxer. Also the inclinaison of the punching bag will be useful.
The captor will be put on the punching bag.
The simple programm of accelerometer works but when i try to edit it in order to transfer the data excel i have a error message "Error :DATA < ASCII 10 or >ACSII 200 with PLX-DAQ....". I can't fix it..
can you help me please ?
thanks you for your help !!
the code is here
The error says that PLX-DAQ won't accept ASCII characters < 10 or > 200.
\t, horizontal tab is decimal 9. Make sure you only send characters which are decimal 10-200 in the ASCII table.
https://en.wikipedia.org/wiki/ASCII
From the PLX-DAQ manual:
For simple error checking, PLX-DAQ will indicate an error anytime that
a string containing characters < ASCII 10 or > ASCII 200 is received.
Values of ASCII 10 (Line Feed) are replaced with ASCII 13 (Carriage
Return) prior to processing.
I suggest you use comma instead of horizontal tab to separate the values.
I have a 1.2 GB .csv file on my disk. I use R's filename = read.csv(path)-function and then I check the object size via object.size(filename) and it turns out, that it's 3721MB large. Why is this difference?
A CSV file is a plain text file and might look like this:
1,2,3,4
3,2,3,2
3,4,2,1
each character (ie digit and comma) is a byte. This file is 24 bytes big (there's an invisible "new line" character at the end of each row).
When read into R each number is stored as a floating point decimal number, which is 8 bytes. The file above would then be 8*24 (values) = 96 bytes big.
It can go the other way. If the above file was instead written:
1.0000000000, 2.0000000000, 3.00000000000, 4.000000000
[etc]
then in the CSV each number is taking about 12 bytes - each digit, decimal point, command and zero takes a byte - and when read in to R would still only take 8 bytes as floating point decimal values.
I am facing hard time in removing the special characters from the csv file.
I have done a head -1 so i am trying to compare only 1 row.
wc filename shows it has 1396 byte count
If i go to the end of the file the curson ends at 1394.
In vi I do set list (to check for control characters), i see a $ (nothing after that), so i now know its the 1395 byte count.
Can someone please tell me where is the 1396th byte?
I am trying to compare 2 files using diff and its giving me a lot of trouble.
Please help.
The last 2 bytes of your line are \r\n - this is a Windows line ending. dos2unix converts this into a Unix line ending, which is \n - hence the line is shortened by 1 byte following conversion.
When I am trying to paste the character » (right double angle quotes) in Unix from my Notepad, it's converting to /273. The corresponding Hex value is BB and the Decimal value is 187.
My actual requirement is to have this character as the file delimiter when I export a .dat file from a database table. So, this character was put in as the delimiter after each column name. But, while copy-pasting, it's getting converted to /273.
Any idea about how to fix this? I am on Solaris (SunOS 5.10).
Thanks,

ASCII only defines the character codes up to 127 (0x7F) - everything after that is another encoding, such as ISO-8859-1 or UTF-8. Make sure your locale is set to the encoding you are trying to use - the locale command will report your current locale settings, the locale(5) and environ(5) man pages cover how to set them. A much more in-depth introduction to the whole character encoding concept can be found in Joel Spolsky's The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)
The character code 0xBB is shown as » in the IS0-8859-1 character chart, so that's probably the character set you want, so the locale would be something like en_US.ISO8859-1 for that character set with US/English messages/date formats/currency settings/etc.
