stm32h7b3i-dk : How to add arm_math / dsp to touchgfx application

[AmrithHN]

Hi,

I was able to successfully use arm_math.h in stm32cubeIDE and I did the same for the touchgfx application generated cubeIDE project.

But when I tried compiling the same with touchgfx , it was showing an error  "arm_math.h" not found however , building the stm32cubeIDE project generated by touchgfx builds fine.

I am totally lost how to integrate DSP library to touchgfx so it can flash along with UI

Hello,

Maybe this article can help you.

Thank you for responding.

I had followed the same while setting up stm32cubeide. problem is that touchgfx doesn't see those and uses a different make files to build project.

Basically touchgfx needs to see the config that stm32cubeide compiler settings/ include paths etc. I am so. confused why touchgfx uses a different makefile for building project.

Thank you!

Although my issue was not with FFT library.

I found the solution for my own problem

- Do not press flash on Touchgfx Designer

-After Generating code from Touchgfx Designer, just edit in stm32cubeide as usual and flash from stm32cubeide (not touchgfx Designer)
