In that script there is the step Unfortunately, the log does not state which pin you are using for the StallGuard. Maybe the pin is used otherwise by the RPi3. You should try a different pin. |

I connected the DIAG to the GPIO pin 17 and tried the mentioned pin 26 from your Readme too. But it does`t matter, I run into the same error every time. |

This problem has propably nothing to do with this library. The problem is either in your Operating System or in the RPi.GPIO library. This is the minimal code setup for testing your problem. (In the 60 secs the main thread sleeps, it should print "Event on Pin 17" if you pull Pin 17 from LOW to HIGH), but it will most likely also fail with the same error as before. import RPi.GPIO as GPIO
import time
PIN = 17
def callback(channel):
print(f"Event on pin {channel}")
GPIO.setmode(GPIO.BCM)
GPIO.setup(PIN, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)
GPIO.add_event_detect(PIN, GPIO.RISING, callback=callback, bouncetime=300)
time.sleep(60)You could also try using |

I tried to use the Stallguard so i tested the
demo_script_04_stallguard.py. The motor starts with moving but after ~2s it stops and the error RuntimeError: Failed to add edge detection is shown.I have set up my TMC/motor/RPi3 along your Readme and double checked all the GPIO wiring (and given pin-nr in the code). I also installed the newest version of the GPIO and your TMC lib directly from pip.
Do you have some ideas how i can fix this?
Here is, what i got from the log:
