USB callback function for STM32-USB-FS-Device library

Hi all,

I'd like to define a callback function which can be invoked when USB receives something from the host.  Where should I implement this in the STM32-USB-FS-Deivce library?

I know that in Atmel ASL I can do something like this:

Code:

void uart_rx_notify(void) 

{ 

   while (udi_cdc_is_rx_ready() ) 

      pxMBFrameCBByteReceived(); 

} 

But not sure how to implement in the STM32-USB stack.

Hope someone could help, thanks!

Well we have

USB_To_USART_Send_Data() in

STM32_USB-FS-Device_Lib_V4.0.0\Projects\Virtual_COM_Port\src\hw_config.c

Called from

EP3_OUT_Callback() in

STM32_USB-FS-Device_Lib_V4.0.0\Projects\Virtual_COM_Port\src\usb_endp.c
