I want to use libarm_cortexM3l_math.a with Arduino Due. Project includes:
#include <Arduino.h>
#define ARM_MATH_CM3
#include <arm_math.h>
arm_max_f32(&sig_src_arr[0],5,&_max,&_index);
Comiling fails with message:
.pioenvs\due\src\main.cpp.o: In function setup': main.cpp:(.text.setup+0x18): undefined reference to
arm_max_f32’
collect2.exe: error: ld returned 1 exit status
*** [.pioenvs\due\firmware.elf] Error 1
libarm_cortexM3l_math.a is part of sam/CMSIS
What configuration i’m missing here?
