Hi there,

I just wondered if the code

return (dtt_read(sensor, DTT_READ_TEMP) / 256);

would be result in a "shift by 8" or and interger division?

Thanks,

Steven

Short answer: Yes.

Longer answer: It depends on the compiler, target processor, and optimization levels. Usually it will be a "shift by 8" (which may or may not actually be a shift -- see the PowerPC "Swiss Army Knife[tm]" instruction rlwimi).
