Hi all,

Plugging away at my LED project. I'm currently trying to combine 3
separate 8 bit values into one 24 bit value (stored in a 32 bit
variable), and I've come across some weirdness.

As part of my function, I've broken things down farther than I usually
would to help isolate the problem. I now have this code:

    greentemp =3D green * 0x10000;
    redtemp =3D red * 0x100;
    bluetemp =3D blue;

The temp variables are all uint32_t, and the input values are all
uint8_t. The goal is to shift the values over so I can then add them
together.

When I execute this code with all of the input values as 0xFF, things
are weird. Green (*0x10000) and Blue (*1) work fine, I end up with
0xFF0000 and 0xFF, respectively. However, redtemp ends up with
0xFFFFFF00, which I can't explain.

Changing the red multiplier to 0x10000 (just as a test) works.
Changing it to 0x1 works as well. But...0x100 doesn't.

I know I'm probably missing something simple here, but I can't seem to
figure it out.

Help!

A common mistake that people make when trying to design something
completely foolproof is to underestimate the ingenuity of complete
fools.
