I added some code to the while(1) loop in the example main so that it writes a message every couple of seconds. I built, downloaded and ran it on my target, and am able to see the messages using a terminal app on my PC. However, I would like to add a loopback feature to read characters typed in the terminal app and write them back. I'm using the CDC_Transmit_FS function to do the writes. But I'm not able to use the CDC_Receive_FS function for the reads because it's declared static in usbd_cdc_ifc.c and is not declared in usb_cdc_if.h. Is there a different public function that I should be using for the reads ? Thanks.
