Hi Dirk,

If you only want the result to be a 1 or 0 (E.g for bit 4 ) then I would use the format:
Bit = Byte & 16 - (16-1)

Or of course you can use Bit = Byte & 16 - 15
Just so long as the last value is 1 less of first number

You could use other formats:
E.g Hex: Bit = Byte & 0x10 - (0x10 -1)

Or Binary:
Bit = Byte & 0b10000 - (0b10000-1)

Hope this helps.

Hi Matin,

cool, this works well!

Ok, how to: Combine a Byte 8 bit and a Byte 4 bit to a Byte with 12 bit word lenght.
8 bit word is lsb, 4 bit word is msb, and - later split them back to original word lenght.
Hope you understand my bad english

Thank you very much

Dirk
