Hey,  
when I run the keyboard.py example the following error happens:

Traceback (most recent call last):  
File “keyboard.py”, line 32, in  
@buttonshim.on\_press([buttonshim.BUTTON\_A, buttonshim.BUTTON\_B, buttonshim.BUTTON\_C, buttonshim.BUTTON\_D, buttonshim.BUTTON\_E])  
File “/usr/lib/python2.7/dist-packages/buttonshim/ **init**.py”, line 294, in on\_press  
setup()  
File “/usr/lib/python2.7/dist-packages/buttonshim/ **init**.py”, line 186, in setup  
\_bus = smbus.SMBus(1)  
IOError: [Errno 2] No such file or directory

Does anybody have an idea what the failure is?

That’s usually a connection problem between the SHIM and your Pi. Could you post a photo of the soldering, please, and how you’ve connected it so that we can check it?

Hey everyone. I have finally found the solution of my problem. It was not a connection problem as supposed, however, the I2C option had to be activated in the raspi-config menu under the point “interfacing options”.
