libgpiod 1.4.2 or older results in error: '<' not supported between instances of 'builtin_function_or_method' and 'int' #685

Closed how2flow closed 1 year ago

how2flow commented 1 year ago

If the Using libgpiod version is low, the following error might occur. (I am using libgpiod v1.4.2.)

...

'<' not supported between instances of 'builtin_function_or_method' and 'int'

Logs that appear after https://github.com/adafruit/Adafruit_Blinka/pull/678 is reflected, i.e. when you use pip package version 8.19.0 or later. Run command sed -i s/num_lines/num_lines\(\)/g {your_prefix}/microcontroller/amlogic/meson_g12_common/pin.py or Change the version to 8.18.1 or lower. Fixing a simple error line may have some side effects. I recommend that you lower the version.

I leave a message for those who meet the error log.

It appears an attempt was made to update this file to work with both older and newer versions of libgpiod as evidenced by snippets of code like:

if hasattr(gpiod, "Chip"):
    chip0 = gpiod.Chip("0")
    chip1 = gpiod.Chip("1")
else:
    chip0 = gpiod.chip("0")
    chip1 = gpiod.chip("1")

However, it appears that some of the logic may have been missed.
