2º) How I active the C11 mode en PC Creator 3.3??

   


3º)How is the implementation for to the "pow" instruccion and "complex" number

Creator 3.3 uses GNU gcc 4.9 which is fairly recent. I just tried adding the command line switch '-std=gnu11' to the compiler, and it worked fine on a simple sample project. '-std=c11' doesn't work since Creator generates some code thats not really standard compliant.

   

Go to project / Build settings, ARM GCC / Compiler / command line and add it there. Maybe you need it for the linker too, I did not test this on real hardware 🙂

Hi hi, thanks for your comment. yes I had trying with -std=c99 but now i will put c11. do you know how implement math function or complex number with PSoC?.
Also, do you know where is the valid list of C command ?

Don't use 'c11', it won't work.

   

But you confuse me. You insist in using C11 but are asking about "valid C commands". Are you looking for a C reference (such as the one from GNU: http://www.gnu.org/software/gnu-c-manual/gnu-c-manual.html )? Or dou you look for a reference to the C standard libaries (see http://www.cplusplus.com/reference/clibrary/ - note that some of the libraries have no meaning on an embedded system)?

   

AFAIK there is no C standard library for complex math functions, and you cannot easily use C++ in PSoC Creator. For math, add 'math.h' as an include, and then add libm to your project libraries (see the knowledge base: http://www.cypress.com/knowledge-base-article/using-math-functions-psoc-creator-psoc-4-or-psoc-5lp-g... )
