How to convert a bytearray(1) value to a 0-255 (uctypes.UINT8)....

[ADenislebel]

I just about feel ashamed to ask but my C programmer brain just can't comprehend why this seemingly trivial
task is so convoluted in MicroPython v1.24.1 on 2024-11-29; Raspberry Pi Pico with RP2040.
The context: I'm reading a port byte from a io_expander that gets load into Buf = bytearray(1).
Then I need to get the value (0/1) of each io_bit 0-7 using the following:
bit_val = (value >> io_bit) & 1
My problem is how to convert the bytearray() Buf variable converted to an int value that will work in that
line of code. If I put a fixed 0b00110011 as the value in line it works fine.
I've tried value = int(value), it reports a syntax error something about wrong base value.
Also tried value = bin(value) it works but fails to value created fails in the bit_val = (value >> io_bit) & 1
I might be able to use uctypes import to do the work but when I did that in the passed
I couldn't even print any of the uctypes structure elements as it immediately crashed the interpreter
and only a reset/power down/up got me back.

data = bytearray((0x55,))
value = int(data[0])

The int() is not needed. The value of data[0] is already an int.

data = bytearray((0x55,))
value = data[0]

You're right of course. What was I thinking… ;-)

Well I suspected it was a simple fix. Your suggestion worked on first try. The differences between MicroPython and CPython make it difficult to know the syntax of the builtin functions. The short and dry reference type of documentation from the Python.org site is tricky to interpret. Thanks again for contributing to my home automation "HomeStat" conversion from an older PIC18F4620
Mcu in C to a new PiPico in Python.
