Ishita:

You are confusing the *human-readable representation* of numeric data

with the actual value of the stored data. The method to convert to any

particular radix *for display* depends on the code or tool that you use

to print or display it. Perhaps if you tell us something about that,

someone can suggest an appropriate method.

If you are writing C code to display the data, for instance, you can

simply use one of the printf() family functions with the appropriate

format specifiers. In your case, wanting to display the data in

hexadecimal notation, you would likely use the '%X' specifier, or

perhaps modify it to provide more consistent formating: '%02X', for example.

Hie,
I have received data in waveform record which is as follows:

datavme 72 53 51 -2 -19 127 -1 50 50 50 50 50 50 50 50 50 50 50 50 50 50
65 50 80 -14 50 64 70 -48 50 50 50 50 50 50 50 50 -113 -113 -128 -128
-128 -128 -113 -113 -113 -113 -113 -113 -113 -113 -113 -113 -113 -113
-113 -113 -113 -113 -128 -128 -113 -113 -128 -128 -113 -113 -113 -113
-113 -113 -113 -113

Please tell me how to convert this data in Hexadecimal format i.e. how
can i get output as

datavme 72 0x35 0x33 0xFFFFFFFE 0xFFFFFFED 0x7F 0xFFFFFFFF 0x32 0x32
0x32 0x32 0x32 0x32 0x32 0x32 0x32 0x32 0x32 0x32 0x32 0x32 0x41 0x32
0x50 0xFFFFFFF2 0x32 0x40 0x46 0xFFFFFFD0 0x32 0x32 0x32 0x32 0x32 0x32
0x32 0x32 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF80 0xFFFFFF80 0xFFFFFF80
0xFFFFFF80 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F
0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F
0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF80
0xFFFFFF80 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF80 0xFFFFFF80 0xFFFFFF8F
0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F 0xFFFFFF8F
0xFFFFFF8F.

I have tried using scalcout record as :

record(scalcout, vmehex1) {
   field(SCAN, "Passive")
   field(DTYP, "Soft Channel")
   field(CALC, "'0x'+AA")
   field(INAA, "datavme")
}

but this gives hexadecimal output of just first array index.
