Re : Re: How to invert a byte ?

[xela75]

What i want to do sounds simply so far but i can't find out a solution which can be that simple...

I have an array of byte for example : 1101 1010 and I'd like to invert it like this : 0101 1011

I did not find the VI to do this. I think it's not a Big/Little -endian issue. I have an idea about converting the byte in string and use the string revert VI. Then get back to byte but it's not optimised.

Have you got ideas ? 

Thanks for the help !

It looks like you have an array of bits, however the easiest is to get a numeric representation of the byte (an U8) and use the boolean invert function.

You propably want to XOR it with a bit-mask.

xela75,

It sounds like you want to reverse the bit order of a U8?  If so, try this.

Wayne.C,

It's weird that there is not a VI which does it...But your solution is interesting.

[xela75]

Your solution is a good one !

Thank everybody for the help !

Just for fun: (the hex constants are U64)
