Convert a I8 binary chain to a U8 binary chain ?

[Acouphenix]

Hello.

I use LW 6.1 and an Lecroy oscilloscope (9450A).
I take datas in binary format. The oscilloscope sends binary data with 8 bit and 16 bit signed numbers (I8 and I16). For a fisrt time, i take the 8 bit signed format.

A software take this binary datas with 8 bit un-signed format.

The data is a block of strange characters.

I use "conversion of a chain to octet" but i have a I8 data.

How I convert I8 binary data to U8 binary data?

Thanks

The binary data remains the same, you just need to tell LabVIEW to either interpret it as U8 or I8 as desired. For this you would use typecast. Check the online help for more details.

Binary data always looks like garbage if you display it as string in normal display, because most octets are not displayable ASCII characters. Do you have a single I8 value or an I8 array?

I don't know what "Conversion of chain to octet" means. Are you using using "String to byte array"?

Attached is one example how to cast a string to an I8 array. You can use the same technique to go from an I8 array to an U8 array ot to a string.
