CDC receive data notification

hello

thanks for the response, but the problem is how can i know when
data is received because i am using CMSIS RTOS.

is there any event sent by USB_CDC TASK when data are availlable
in receive buffer.

thanks

Event is not set but function that you implement in your code with name USBD_CDC0_ACM_DataReceived will be called when new data was received

So you define function

void USBD_CDC0_ACM_DataReceived (uint32_t len) {
  // Something was received
}

hello Milorad

thanks for the information.

i have tested it and it works fine.

thanks again
