Making a UART - USB pass through
================================
It's as simple as::
import pyb
import select
def pass_through(usb, uart):
while True:
select.select([usb, uart], [], [])
if usb.any():
uart.write(usb.read(256))
if uart.any():
usb.write(uart.read(256))
pass_through(pyb.USB_VCP(), pyb.UART(1, 9600))
