SUPER BASIC QUESTION on CMSIS FFT INSTALL

I have a very basic question. I have been trying to get the CMSIS FFT library installed without success. I have tried linking in the following libraries: Simon Fords Real FFT Library: https://developer.mbed.org/users/simon/code/dsp/ CMSIS_DSP_401 https://developer.mbed.org/users/emh203/code/CMSIS_DSP_401/ Then I included the following h file:

  1. include "arm_math.h"

When I try to compile I get an error: Identifier TableSize is Undefined.

What am I missing? Thank you for your help! Craig

I've tested this on mbed 2.0 and mbed OS 5.4 on a NUCLEO F411RE with the CMSIS_DSP_401 library and that compiles fine. mbed OS 5.5 will not work as it uses CMSIS5.

Don't add both libraries though.

Jan, Thank you for looking into this. The need for CMSIS5 and not CMSIS is what did me in. Thank you again. Craig
