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:
- 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.
