Hi!
I’ve spent quite a lot of time doing research about how to use GPIO pins on my Raspberry Pi since it doesn’t work with RPi.GPIO as the older versions do.
I found two useful libraries: gpiod and gpiozero, but none of them work for me.
First, let’s dive into gpiod.
I copied and pasted the example code you can see in the PyPI website:
and I got this error message:
Then, I changed chip0 to chip4 and still got the same message.
I tried other codes that included the function “get_line” and I always got the error message:I also tried to use this ‘get_info’ function, but I didn’t get to any point.
I looked in the forums and everyone seems to get ‘get_line’ working. I think it’s due to the new update. It says in the lint documentation that the new version has reworked the way of using lines.
About the gpiozero library, I tried to blink a LED using this code from the documentation:and got the error message:I thought this has something to do with the wiring, but I triple checked it and I can say it’s alright.
Does anyone what could I try? I’m quite lost now (as you can tell) and it would be very helpful if someone could help me![:)]( "Smile")
Thank you in advance.
