Hello everyone, I am trying to use the function arm_rfft_q15() which is defined in line 2208 [here][1]. My code is as follows: #define ARM_MATH_CR3 #undef A0 #undef A1 #undef A2 #include "arm_math.h" const arm_rfft_instance_q15 *fft; void runFFT(const arm_rfft_instance_q15 *fft, int16_t *p, int16_t *q); int16_t random_array[1024], outputbuf[1024]; void loop() { runFFT(fft, random_array, outputbuf); delay(1000); } void runFFT(const arm_rfft_instance_q15 *fft, int16_t *p, int16…
