After generating the code I Middlewares folder was added. I adding ARM_MATH_CM4 in Symbols (I'm using stm32F446RE NUCLEO) everything looked good. I then type #include "arm_math.h". but when i build projet there are multiple errors in arm_math.h files. some errors are about float type definitions. any tips?
@@steppeschool3629 I'm sure. I did successfully included it in the end. turns out in the new versions of CubeIDE you can download DSP library from Pins & Configurations UI and then just write two lines in the includes: #define ARM_MATH_CM4 (because I'm using F4 series) and #include "arm_math.h"
@@steppeschool3629 okay. you mean fir_instance[12], fir_in_arm[12] and fir_out_arm[12] is only modification in program for 12 ADCs? or something more nedded? am I correct?
The filter was designed for a 1 kHz sampling rate. The details can be found in this video: ruclips.net/video/9J7NyZ6WKv8/видео.html I controlled the sampling rate using the TImer Update Interrupt's frequency: ruclips.net/video/KtVFYXtHvWc/видео.html
Hi, there are many reasons why the st-link is not detected. Usually, the boards have several USB connectors, one for the st-link. First, make sure that you connect the right USB socket. Also, the STM32 boards possess jumpers to connect STM32 MCU ST-LINK pins to the corresponding pins of the ST-LINK. Make sure that they are in place.
@@steppeschool3629 i plugged in the usb stlink, and on keilC detected and downloaded normally. But not with cubeIde. I also used stlink utinity connect and detect stlink normally
Hi, I shared the source code on the community page: www.steppeschool.com/products/communities/steppeschool-miscellaneous You can also find the source code and additional materials for other projects

I just want to inform you that the source of the projects, including this one can also be found on my Patreon page: patreon.com/user?u=80399744&Link&
Hello, Have you tutorial of RTOS? Thanks
My god after 2 hours of searching! Finally something useful! THANK YOU
Glad to hear that!

I have never had such an issue. Are you sure that you added the symbol in the proper place? (paths and symbols, GNU C)

Filter coefficients are initialized from double literals and casted to float32_t. Assuming float32_t is float this should give warning
IS IT POSSIBLE TO IMPLEMENT THIS ON MULIPLE ADC CHANNELS? I AM USING FOR SING CHANNED BUT FAIL TO IMPLEMENT ON MULTIPLE ADC CHANNEL..
of course you can. Just create multiple instances

Very clear explanation, good job!
thanks!
That filter for what sampling frequency is it designed? what did you put on your clock?
The filter was designed for a 1 kHz sampling rate. The details can be found in this video:

I controlled the sampling rate using the TImer Update Interrupt's frequency:

Hi, i have board f407discovery. But on stm32cubeIDE no detected st link. How to fix it?

Then, what do you mean by STM32CubeIde does not detect the st-link? Can you not flush your code to MCU?
Very useful. Thank you!
Glad it was helpful!
Where can i download the code?
