Number convert to hex string and write to port

[shubhlaxmi22]

Hi,
       i want to convert decimal number to hex string.i am using global variable as decimal integer.i want single data from globle variable as a single bit,means 8 globle variable as a 1 byte.

Hi shubhlaxm…,

here is an example.

Hi,
     i dont understand can u explain it in brief.how to make that constant.

Hi shubhlaxm…,

i thought you have 8 numbers which you want to combine. If you only want to convert a number to a hex string, then only use the "Number to hexadecimal String" function.

Create a numeric constant. Right click and get properties. select "show index" in the appearance tab.

Then you can choose index like decimal, binary, octal or hexa....

We cannot help you because we don't know what you have and wat you want. Your question is not clear.

What is the datatype of the global variables? If each integer is one bit and you have 8 of those, we need to know how they map to the bits. (e.g. "0,1" for "bit set/not set", resp.).

Then we also need to know whay you mean by "hex string". Is it a hexadecimal formatted string consisting of the letters 0..F, each representing a nibble, or do you want a binary string where 1 byte represents your 8 bits.

One solution might be to make an array of your 8 globals, wire it to a "not equal zero", and then convert the result to a number using "boolean array to number". If you want a bunary string, you would then typecast it to a string. If you want a formatted string, you would use "number to hexadecimal string".

The following code converts 8 "0/1" values to a binary string. Modify as needed.

Hi,
     Thanks it works properly.

Hi,
     It works but when i connect more than 8 global variable means 9th variable to build array then what happens?

Hi shubhlaxm…,
if you need more inputs, then you can resize the build array function. I recommend to visit the free courses on the ni site.

hi,
    when i connect 8 global variable it gives me output in BCD count but if i want 9th variable as a first then what should i do when i resize that array.i am sending u attachment see my logic. consider 8 variable means 1 byte  then from 9th to 16th  2nd byte.is it right ?
