Hi everybody,

I've recently needed a fixed-point atan2() function for my day job.

I looked around and didn't find anything ready-to-go for a 16-bit
microcontroller.

So I wrote a script to generate this function using a CORDIC
algorithm.  I put it online at http://vivara.net/cgi-bin/cordic.cgi

The python source is available, but it requires a native C compiler to
run the tests against the generated code.  I tried to make the
generated code something that any C compiler could apply optimizations
on.  I think it would be straightforward to "hand compile" it to
assembler as well.

Suggestions and bug reports welcome.

Regards,
Mark
