So, most of the examples use USB CDC driver and they bridge UART. I'm not embedded guy and learning the stuff one by one. So, I understand UART... But I'm a bit confused how this bridging works. Is uart a virtual driver kind of thing or physical component inside the MCU. How does this bridge of USB CDC driver work though USB and UART are components by themselves ?
I read this question, Does USB CDC always use a UART channel?
But I need more insight to understand this bridging. Please explain the bridging thing as well in details.
Because the confusion is UART itself needs pins configurations... so pins are physical and how the bridging works.
