I'm configuring a STM32F205RET for SPI: hspi1.Instance = SPI1; hspi1.Init.Mode = SPI_MODE_MASTER; hspi1.Init.Direction = SPI_DIRECTION_2LINES; hspi1.Init.DataSize = SPI_DATASIZE_8BIT; hspi1.Init.CLKPolarity = SPI_POLARITY_LOW; hspi1.Init....

I'm thinking that maybe the NOE pin (labeled USB_NOE and activated in Connectivity/USB-Device) may play a role to indicate USB data activity.The problem is that this NOE functionality is very poorly documented, there are no code samples anywhere.

I'm finding methods like EP0_TxSent and USBD_LL_DataInStage, but I'm not finding a simple interrupt or callback to indicate 'a USB data packet was sent or received.'I want to implement that interrupt and blink my GPIO connected LED inside it.

The problem was solved by correcting a delay_us(3) implementation. This delay was present in between some RESET (NSS) line toggles, and it seems to have appeared as a SPI serial problem (but it was not.)

How can I light a LED to indicate USB DFU data activity?

Using STM32CubeMX to make a DFU bootloader, I want to light a LED whenever USB packets are exchanged, to indicate that a DFU binary is being transferred. ...but I can't find the right callback to place my HAL_GPIO_WritePin. What is the callback to use?
