Seems to work pretty well even for things that require rather short update intervals (10 ms), for PWM control of a motor with an encoder.  I'm not sure if it could run much faster (I haven't attempted to measure the time it takes to execute a cycle).

Is there any chance of an integer version of the library?  Integer math would certainly run faster on the ATMega168, since it's doing floating point emulation in software.  This might also cut down on footprint, but I would hope that the compiler isn't spitting out copies of all the instructions needed for fp emulation at each stage they are used.

Ubuntu 8.10, 32-bit, Arduino 0012, Duemilanove.

Same issues here. Weird...

I also tried 0011, and it seems to give me the same problem.

Has anyone found toolchain/arduino combination that gives reasonable behavior on linux?
