Not very much, I use assembler. Library should be OK, as it's gcc. There are
other compilers apart from IAR. ImageCraft's is pretty good, and quite
but I'm not sure if it has fp yet. My beta test copy didn't, but that was
some months ago. Also, Imagecraft is very responsive and helpful.

Many of the packages for the low-end chips are quite easy to work with,
using home-made PCBs. I've done several PCB designs for them.
Olimex sells a low-cost FET for the MSP430 ($9) and some useful evaluation
