Extra Keyword Arguments Given using uart.init

[HopWorks]

Hello,

I am using Micropython on a PI Pico W. with Thonny 4.0.2 and I am trying to use uart.init to set parameters but I keep getting an error.
USING...

>>> sys.implementation
(name='micropython', version=(1, 20, 0), _machine='Raspberry Pi Pico W with RP2040', _mpy=4358)
>>> sys.platform
'rp2'

TypeError: extra keyword arguments given

uart = UART(0, tx=Pin(12), rx=Pin(13))
uart.init(115200, 8, None, 0, timeout=10, timeout_char=10, read_buf_len=512)

And I also tried...

uart = UART(0, tx=Pin(12), rx=Pin(13))
uart.init(baudrate=115200, bits=8, parity=None, stop=0, timeout=10, timeout_char=10, read_buf_len=512)

with the same results.

I hope I fully read https://docs.micropython.org/en/latest/library/pyb.UART.html correctly.
I googled this for an hour and cannot find where I went wrong.

Thank you for your time!!

uart.init(115200, 8, None, 0, timeout=10, timeout_char=10, read_buf_len=512)

There is no read_buf_len on machine.UART. You want rxbuf I think.

I hope I fully read https://docs.micropython.org/en/latest/library/pyb.UART.html correctly.

That's the docs for the (legacy) pyb.UART class that just exists on stm32/pyboard. You want the docs for machine.UART.

That is interesting. I thought they were all the same thing. Thank you for that clarification!!
It is too bad the error thrown could not have said there was an unknown named parameter instead of 'extra keyword arguments given'. That might have made a difference in my search criteria, but I probably would have ended up at the same dead-end.
This also helped me to figure out why readln() didn't work either.
Thank you sir for your reply!!
