Bare metal, and preferably Assembly as you need every byte in those 32KB/2KB.

Bare metal: Probably yes, if you don't need the services of an multithreading-OS.

Assembly: probably no. Have a look at what people are doing in C++ on the Arduino platform (the Mega328 has the same Flash/RAM).

Ok, I thought Arduino had more capacity.
