Is there USB Library for STM32C071 without Azure RTOS

[Bassem]

Dear community,

I'm not a big expert of USB and I have a solution based on STM32C0 and I would like to extend it to use USB, STM32C071 is the prefect candidate, but for my big surprise the USB stack is based on Azure RTOS, this is kind of killer for us, actually it will be a nightmare to include it, so my question is there any solution offered by ST which include USB library without the layer of RTOS.

Just another question out of curiosity why Azure RTOS was introduced in ST Package in first place.

Hi @Bassem 

Here you can find example firmware for USB standalone (withtout RTOS). Azure RTOS was introduced in ST package to provide an additional solution to developers. For existing products, support for FreeRTOS continues alongside Azure RTOS, called X Cube AZRTOS. While for H5 U5, C0 products and so on, Azure RTOS is the native solution.
