Hello everyone, I am making a USB Composite Device according to the article - https://sudonull.com/post/68144-CDC-MSC-USB-Composite-Device-on-STM32-HAL. I use stm32l4xx, instead of the HAL_PCDEx_PMAConfig() functions, I use the HAL_PCDEx_SetTxFiFo()/...

I use stm32l4xx, instead of the HAL_PCDEx_PMAConfig() functions, I use the HAL_PCDEx_SetTxFiFo()/HAL_PCDEx_SetRxFiFo() functions. Could you tell me how to configure them correctly for Composite USB? Thanks in advance.

Good afternoon, please tell me what role the USBD_HandleTypeDef type structure plays in the USB driver

STM32L4xx USB Composite Device

Hello everyone! I'm using an stm32CubeIDE to implement the usb audio class using the internal DAC by DMA. How can this be implemented, as I understand it, all the magic is in the AUDIO_AudioCmd_FS function. Thanks in advance.

How using the cubeMX program to implement the usb composite device?

Hello. Does anyone have a configuration example for stm32f103 uart in half-duplex mode(switch TX/RX modes) using Low Level Library. Thanks!
