<![CDATA[UART Equal function always returns false]]>For context, I am trying to adapt a Marlin 3D printer smart screen by connecting it to M5Station Port.C1 and the UART response I am expecting (and that is being sent) is "M105". However when I compare the UART variable (which is the decoded UART response) to the code being sent "M105" it always returns false regardless.
Here is the snippet of code if it helps to diagnose:
uart1 = machine.UART(1, tx=14, rx=13)
uart1.init(115200, bits=8, parity=None, stop=1)

while True:
if uart1.any():
UART = str((uart1.readline()).decode())
if UART == 'M105': #This erroneously returns false regardless
pass
wait_ms(2)

if I am not mistaken readline() returns the newline \n character at the end. This could be the reason for the comparison to return false.

Thanks
