hello,
trying your setup and code with last Ubuntu 22.04.1 LTS image, i first get an error executing that line : chip = gpiod.Chip('gpiochip0') with the error : “No such file or directory”.
That was strange, as the gpiodetect was listing gpiochip0 (and also gpiochip1, names shortened) as expected.
So checking the filesystems, i found a “real” path beeing ‘/dev/gpiochip0’, so i change the above line to chip = gpiod.Chip('/dev/gpiochip0') and from then i was able to control the pin 40 to light on/off the LED of the schematic.
Reading a stable input from pin 38 (connected to button) is still erratic but it s more my wires that are not well set i think (so out of line here ;-)).
