Hello everyone,
could not find answer here nor on the web. Pretty strange ... the system returns an error but seams to work anyway. I want to eliminate the error.
Such is my code (lines 1-11)
Such is the error message:
such is the code (lines 701-706)
and about File "/usr/lib/python3/dist-packages/lgpio.py", line 903, in gpio_read
such are lines 887-903I also tried sending default values like this:but an other error shows up, something like « can not set value on PULLD when OUTPU »
Any idea ?
Thanks.
