Did you find a solution ?
I made a new project in openstm32 and get sound to work perfect...
Now i want to add FFT from cmsis and i did ;
- include “stm32f7xx.h”
- include “stm32746g_discovery.h”
- include “main.h”
- include “math.h”
- include “arm_math.h”
but iit fails here
arm_fir_init_q15 (&SFIRleft, NUM_TAPS, firCoeff, pFIRStateLeft, NUM_SAMPLES);
and i did add ARM_MATH_CM7 to the SYMBOLS tab in project properties paths and symbols
What did i miss ?
