Forum: System Workbench for STM32

empty project using HAL and USB device middleware

Posted by benjamin.brammer on 2016-09-23 18:12

Hi guys!

I am new to the STM32 family and tried to start an empty example project. With your step through by clicking New- -> c-project, I thought this goes pretty well. But when I just want to compile the main I get the error, that “usbd_conf.h” is not found?

SW4STM32 is up to date and i am using an NUCLEO-64 with an STM32F446RE

best regards

Benni

Try to start with CubeMX.
As soon as you set USB interface available, it immediatly will open a set of USB devices available for your chip. You justl need to choose the one you want to use.

when I run CubeMX and select the Nucleo-64 STM32F446RE I get an unresolvable error in the clock configuration. Seems as if the chip expects an HSE input. but why that? I can also achieve the respective Clocks with the onboard HSI..
and isn’t it possible to create a project with HAL without using CubeMX? After all the Nucleo-64 board description doesn’t say something about USB restrictions..

ok, i ignored the fault and generated the code but it’s not really working.
What would anyone suggest for a good starting point to evaluate the module step by step. CubeMX looks really great, but its also so powerfull that I need to make small steps in the beginnig. Are there some working examples?

I checked CubeMX for your board. Seems like HSE is not possible to use. Probably some peripheral use XTAL pins on this board.

It is possible, but CubeMX makes life easy with building all initialization and creating a starting point project.

Download CubeF4 from the ST side. It provides a lot of good demos.
