CCS C and Fuzzytech

I use CCS C and Fuzzytech.I create my project on Fuzzytech. Then I want to use file created by Fuzzytech in c language. But Fuzzytech using bit pointer CCS C do not support it. What can I do? If you want I can gives the sample code.

Sure. Post a small section of code that shows how they use the pointer
and also post the variable declarations.

in my created file
typedef unsigned short FUZZY;
FLAGS myproj(FUZZY lv0_In1, FUZZY lv1_In2, FUZZY *lv2_Out1);

in include file

typedef unsigned short FTCRTU16;
#ifdef FTLIBC16
typedef FTCRTU16 FUZZY;

How do you know that FuzzyTech is using bit pointers ?

Normally (in most compilers) a "short" is not a bit.
Defining a "short" as a bit is an invention of CCS.

So I doubt that FuzzyTech really intends to use bit pointers.

My suggestion is that wherever FuzzyTech uses a "short",
you should change it to "int8".

It's possible that it needs to be "int16", but I can't tell from
the code that you posted.

You are really correct. I looks code. It uses int16. Result is perfect with CCS C. Thank you very much...

can you post success code ~~pls~tks.

OK. No problem I changed some definition of variables in FuzzyTech. It gives perfect result with using of 2 tools(CCS C and FuzzyTech).

Hello everybody

Is anybody to help me :

I want to control temperature and humidity by Fuzzy logic. I wrote rule base in Fuzzytech and LabVIEW software and simulated. I got good results. Now I want to implement my fuzzy project by PIC18F452 and want to write the code by CCS. Is anybody that wrote the code by CCS in a project like my project by fuzzy before?

Please send me the code or guide me. How can I write fuzzy in CCS?

Many thanks in advance,

Alireza121

Man I thought Fuzzy 'logic' died years ago !!

It's real easy to port to C, just use a few 'case statement' as fuzzy is really just a bunch of if-then-else type code.

Hi dear

I know C language and also I know fuzzy logic is bunch of if-then rules,my problem is not this,my main problem is about how to define membership functions(rectangular,triangular,...) in CCS compiler?

Please guide me how to write code of membership functions in CCS compiler?

Looking forward to your kind reply,

Many thanks and merry Christmas,

There's tons of code on the Web (google...fuzzy code in C)
but I'm bored so ..
Ok, I'll take a stab at it
