Fixed point Q16.16 atan() function needed

[Johannes Lorenz]

Hi,

i need the atan() function in fixed point Q16.16. Does anybody know a good, small library or some C code for armgcc?

Yours Johannes

Hi,

I would recommend taking a look at the libfixmath library. The library offers developers a similar interface to the standard math.h functions for use on Q16.16 fixed point numbers. For the atan function, use the libfixmath function fix16_atan().

You can download the library from here or here.
