I am struggling to use the DSP library provided by ST for my STM32f3 discovery board. I am using Coide. I started by including arm_math.h since all the DSP library files refer to it.
I am getting these errors a lot(they are all in the arm_math.h file).
unknown type name 'INLINE' expected '=', ',', ';', 'asm' or '__attribute' before 'clip_q63_to_q31'
I have been searching for almost two days now and I can't find any useful solution. I am using currently yagarto as a compiler.
INLINE is an instruction to the compiler to "inline" a function, that is, wherever it sees a function call it copies the code for the function, instead of jumping to a single copy of the code as per a normal function.
This makes the overall code size larger, in exchange for substantially quicker execution of INLINE functions (because there is no call/return overhead).
I've never used the Yagarto compiler, but my guess would be that it either doesn't support INLINE (unlikely) or that it has a different syntax (very likely). Probably a similar story for the other errors that you're seeing.
Try using GCC instead (which does recognise INLINE, and which is probably the compiler that the ST libraries were written for); iirc there's a link to a "current build" that's easy to locate on the CooCox website.
Actually i solved that by adding this line in the beggining of ARM_math.h:
#define ARM_MATH_CM4
