Hi All;
I can't find a listing of all the CFunctions.
I thought there was a library of uMITE code and CFunctions?

I've collected a few on my CG site. I'd be happy to collect more if I can get permission to repost the libraries. I'd like it if the authors would help with this by providing the most recent code and descriptions.

Did you mean CFunctions.h? It's included in the firmware update zip in one of the sub folders.

Hi Justplayin

I'm not sure. I really don't know what I'm doing yet.

I have uMite II 5.2
I can't find very many CFunctions in my firmware about 10 or so.
They are in PDF files. I thought there have been a lot more
I don't see "CFunctions.h"

I thought there was a library where most, if not all, uMITE codes
were held. I guess not.

What I'm looking for is a package that has double precision
Trigonometric functions, either floating point or integer.
I need ACOS, ASIN, ATAN2, SIN, COS specifically.
Astronomical program for solar tracking.

I'm not a real programmer, just a muddling user.

I see... CFunction.h is for writing your own Cfunctions/CSubs. Other than few samples in the firmware zip and some code posted by Peter Mather, there is very little available in pre-made CFunctions. I don't think you will see trig functions from C routines due the limitations of dealing with floats.

From the C Routines PDF:

Quote Floating point constants and variables can also be passed but they need to be handled carefully within the embedded C routine as the C compiler will generate invalid code for normal floating point operations.

There are no Cfunctions to do this and currently no way of writing them
