LabVIEW
Decimal to hexadecimal number
Solved!
Hi Milan,
I need to convert decimal number to hexadecimal number (not a hexadecimal string).
This is just a problem of display presentation (aka formatting options). The value stays the same!
I need to send hexadecimal number to some microcontroller via LIN bus.
it demands to be a array of hexadecimal string.
So you need a string and not a number?
Please check VI in attachment.
Can you attach your VI for LV2017?
Total byte should have 8 bits. 0-5 bit are from red scale, and 6th bit is from toggle switch.
What is the 7th bit?
How to convert to hexadecimal number???
It is not possible to send hexadecimal string, because ASCII is defferent for string and number.
Why isn't that possible?

This is first byte from 8 Byte in Lin data frame. Another byts are hexadecimal numbers form start.

Can you attach your VI for LV2017? I saved in 2016. You should be able to open.
Total byte should have 8 bits. 0-5 bit are from red scale, and 6th bit is from toggle switch.
What is the 7th bit? No information should be sent with 7th bit. It is false.

Why isn't that possible? I am not shure, if number and string has same value in ASCII code.
Thanks
Hi Milan,

No, still the LV2018 version…
This is first byte from 8 Byte in Lin data frame. Another byts are hexadecimal numbers form start.
A LIN frame consists of (upto) 8 bytes. The bytes contain some values from 0 to 255.
Their representation (decimal, binary, octal, hexadecimal) is irrelevant: the value is important!
No information should be sent with 7th bit. It is false.
So there is some information: the 7th bit is FALSE!
I am not shure, if number and string has same value in ASCII code.
ASCII codes also are just bytes. The value stays the same, only the representation changes!
An "A" is the same as 65d, 41x, 1000001b, or 101o…
Hi Milan,
So you are saining that I can send 8byte array of strings to LIN slave...
My LIN driver expects an array of byte, but no string.
Which LIN driver do you use?
Ok, I can try that, but then all byts I need to convert to hexadecimal string.
No, you don't need any "hexadecimal strings"!
All you need is an array of (upto) 8 bytes - and maybe the U8ArrayToString function…
I prefer logical functions to handle bit fields:
Please take note of all those constants and indicators with a visible radix display!
Hi,
I use NI usb-8476 device and NI-CAN package for labview.
I find some example... Is this method OK?
Best regards.
Hi Milan,
I use NI usb-8476 device and NI-CAN package for labview.
NI-CAN doesn't use any strings for CAN/LIN messages. Why do you think so?
I find some example... Is this method OK?
It would be ok, when the author would have used the Auto-Cleanup function…
But it clearly shows: the message data consist of 8 bytes (aka U8 values). No need for any decimal/hexadecimal/whatever conversion!
