(excuse my ignorance )hi, i am working on a module that requires trigonometric functions (sin tan cos etc), im not sure how to implement this, i have looked into the cordic_math.h file, but it seems that is only something used for lua, because when i include it i get lots of errors. i understand that the camera doesnt have floating point hardware. help appreciated. i hope i havent said anything too stupid.

You can just copy the cordic functions into your own file. You might want to look at lib/lua/lfmathlib.c, which uses this approach with actual floating point numbers.

Note the weird switch statements (oneargfn, twoargfn etc) are a size optimization, I would *not* recommend following that example unless you are really concerned about memory, but it should be fairly easy to back out into standalone sin, cos etc functions.
