//! This example shows how to use the PIO module in the RP2040 chip to implement a duplex UART.
//! The PIO module is a very powerful peripheral that can be used to implement many different
//! protocols. It is a very flexible state machine that can be programmed to do almost anything.
//!
//! This example opens up a USB device that implements a CDC ACM serial port. It then uses the
//! PIO module to implement a UART that is connected to the USB serial port. This allows you to
//! communicate with a device connected to the RP2040 over USB serial.
