I would hope the compiler for an 8-bit microcontroller would be smart=20
enough to turn either shifts or multiplys into byte copies.

Interestingly C18 will sometimes turn a shift into a multiply. The PIC18=20
is actually better at multiplication than it is at shifting since it has=20
a multiplier but not a barrel shifter.

You mean

greentemp =3D (uint32_t)green << 16;
redtemp =3D (uint32_t)red << 8;
bluetemp =3D blue;
--=20
