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()/HAL_PCDEx_SetRxFiFo() functions. Could you tell me how to configure them correctly for Composite USB? And for what parameters are these functions responsible? Thanks in advance.
Hello @alfinikov ,
I advise you to refer the working USB application available under STM32CubeL4 MCU package.
Have a look at this UM1734 User manual STM32Cube™ USB device library
For more details on how to use the PCD driver, please refer to UM1725 that describes all PCD driver APIs (in HAL PCD Extension Drive section).
