loading literal constants, and floats.

Is there any way to load a float constant in the assembler as a literal? (without resorting to converting it to hex externally)

It doesn't seem to even recognise float numbers at that point.

I also noticed that anything greater than 16-bits is silently truncated in a mov.

Immediate moves can assign only 16-bit numbers to either the low half of the reg (zero extended) with `mov r1,#val` or to the high half of the reg using `movt r1,#val`. The macros HI() and LO() should help you select the required part of the immediate value.
