I am attempting to send data in bulk, 64 bytes at a time for every SOF interrupt, however I don't see how to enable the interrupt.I attempted defining USE_HAL_PCD_REGISTER_CALLBACKS as 1, but that doesn't seem to trigger the SOF interrupt.

Context: I'm porting code from an old STM32F4 to a ST32H7 for USB FS.In the old code, Handle_USBAsynchXfer is used to transfer large amounts of data 64 bytes at a time.Now that I am using STM32CubeIDE, I don't see HandleUSBAsynchXfer, but I do see CD...

I finally realized that you need to add HAL_PCDEx_SetTxFiFo in the USBD_LL_Init in usbd_conf.c file for the corresponding endpoint.

So, I tried using CDC_Transmit_FS in main and I'm not getting anything either. It goes through and says HAL_OK, but I'm using a USB sniffer and there's nothing on the line.I saw that the old firmware uses USBD_CDC_SOF, and so I added that function to...

Oh, that's what I saw, but for some reason it isn't working for me.I am calling it from an SPI complete callback. Not sure if interrupt priority has anything to do with this.

STM32H7 USB Full Speed SOF interrupt. I used the CDC class as a template to implement a cusom vendor class. It seems to me that the Start of Frame interrupt never fires. How do I enable it?
