You bet :-)))

unsigned int getHexDigit( unsigned int hex, unsigned short
digitWanted )
{
     return ( hex >> ( ( digitWanted - 1 ) << 2 ) ) & 0xf;
}

This version is simpler... just ****fts the wanted digit to the 1's
place and masks out the rest.
Note x << 2 is the same as x * 4. I put extra braces to make clear on
the processing order.

best,

    Michael.
