print on UART0

[CrabbyPete]

I am using Thonny to program my Raspberry Pi Pico in python, and I have print statements to monitor the code. Once its complete I want to be able to connect a battery to the pico and monitor the output of those print statements on UART0. I have and FTDI cable on UART0, but I don't see any output. Is the USB port still active? How can I make the print statements go to the UART0 pins?

You can use os.dupterm() to replicate the standard output to a stream device, like UART. e.g.

import os
from machine import UART
uart=UART(0, 115200)
os.dupterm(uart, 0)

Maybe something like:

u = machine.UART(0,9600,8,None,1)
print('testing', file=u)
