CMSIS-DSP with STM32F302

Dear all,

is it possible to use CMSIS-DSP with STM32F302XXX?

Actually I'm working with NUCLEO STM32F302R8Tx (but final board will have STM32F302RCT6) and I have two issues :

1) I am not able to find lib *.a in repository CMSIS_DSP 

2) Following this guide Guide I get this error ../Drivers/CMSIS/Include/core_cm4.h:105:8: error: #error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"

 

Is there some hardware limitation?

Or am I missing some step?

 

Thank you

Well, the STM32F302R8 does have an FPU - so there must be a problem in your configuration:

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Hello,

    As stated by @Andrew Neil  STM32F302 has a HW FPU.

    Check out the DSP demo provided in X-CUBE-DSPDEMO (STM32F429I-Discovery project) which you can inspire from.
