article

create project whit cubeMx

create base configure then open with keil

add dsp

then you need to remove this item

if you not delete this you will see like this

  • too many errors

then add the arm_math.h to which file you want to add . don't need to add Macro ARM_MATH_CMx can use is directly. this time reduced about 34% than matlab coder.

// arm 通过输入的参数类型将fft分为2大类[real,complex]分别对应的函数名为:
// arm_rfft_xxxx
// arm_cfft_xxxx

float32_t output[128];
float32_t input[128];

// 初始化FFT状态
arm_rfft_fast_instance_f32 fft_inst;
arm_rfft_fast_init_f32(&fft_inst, 128);

// 执行FFT
arm_rfft_fast_f32(&fft_inst, input, output,0);

Other

Wrong method, don’t see below this line

add macro

,ARM_MATH_CM4//H7是CM7，F4是CM4，F1是CM3

use dsp

#include "arm_math.h"
#include "arm_const_structs.h"

build

you need to rebuild not build

if you see like this means you succesfull

there are many warnings, don’t care this this means lack of an empty line
