I have a problem when trying to use arm_math.h. I ve just included the arm_math.h and the core_cm4.h in my main file. when I compiled, I got the error: " #error "Define according the used Cortex core ARM_MATH_CM7, ARM_MATH_CM4, ARM_MATH_CM3, ARM_MATH_CM0PLUS or ARM_MATH_CM0". what did I miss?
I used the mcu k64f and kinetis design studio with ksdk1.3
