Python3 Segmentation Fault with Rotary Encoder

[OliverMardle]

Hi, I just tried to run the example program for the rotary encoder provided and as soon as I turn the rotary encoder the program terminates and gives the "Segmentation Fault" error.

Cheers.

There are three samples for the rotary encoder. Which one gives you an error?

1. https://github.com/guyc/py-gaugette/blob/master/samples/rotary_test.py
2. https://github.com/guyc/py-gaugette/blob/master/samples/rotary_worker_test.py
3. https://github.com/guyc/py-gaugette/blob/master/samples/rotary_interrupt_test.py

My money is on (3). Do the others give the same result?

It would be good to know some more details.

• what board you are using
• what OS you are using
• output from python --version
• output from pip show wiringpi

Hi, Sorry for the complete lack of information I provided... Your absolutely right, the issue occurs only on rotary_interrupt_test.py. The switch works but as soon as I turn the dial I get the error. I'm using a Raspberry Pi 2 at the moment and the latest distribution of Raspbian Stretch. In terms of python I'm using Python 3 and the output of python3 --version is Python 3.5.3 The output of sudo pip3 show wiringpi is:

When I do run the other working programs the rotary encoder appears to be a bit jumpy, I think this must be the stage of the encoder however this can be resolved at a later stage.

Cheers.
