-Making a UART - USB pass through
-================================
-
-It's as simple as::
-
- import pyb
- import select
-
- def pass_through(usb, uart):
- usb.setinterrupt(-1)
- 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))
