Hi, Completely new to all this HAT stuff - bought a DrumHAT thinking “great, I’ll install it and in no time I’ll be tapping out rhythms on it!” Well, it’s fixed to our raspberry pi, and I followed the (brief!) instructions on the github page. When I try to run [drumhat.py](http://drumhat.py) (is this even how I should be going about it?) I get the following: pi@raspberrypi ~/drum-hat/library $ sudo python ./drumhat.py Traceback (most recent call last): File “./drumhat.py”, line 6, in alert\_pin=25) File “/usr/local/lib/python2.7/dist-packages/Cap1xxx-0.1.0-py2.7.egg/cap1xxx.py”, line 239, in **init** self.i2c = SMBus(i2c\_bus) IOError: [Errno 2] No such file or directory Exception AttributeError: “Cap1188 instance has no attribute ‘alert\_pin’” in \\> ignored …and nothing happens. Anyone out there got the DrumHat working? Or any advice as to how I might do so? Thanks! Paddy ---

Hello, in ~/drum-hat/examples try sudo python3 [drumhat.py](http://drumhat.py) ---

Thanks, Darkhammer. Unfortunately I get the message ‘no module named caplxxx’ And pip cannot find the module for me to install in python3 (it’s there in pyuthon 2.7…): pi@raspberrypi ~/drum-hat/examples $ pip install caplxxx Downloading/unpacking caplxxx Could not find any downloads that satisfy the requirement caplxxx No distributions at all found for caplxxx Storing complete log in /home/pi/.pip/pip.log ---

Have managed now to install cap1xxx - when I realised that it was the digit 1 rather than the letter l in the middle… Unfortunately running [drumhat.py](http://drumhat.py) results in the same error as before: pi@raspberrypi ~/drum-hat/examples $ sudo python3 [drumhat.py](http://drumhat.py) [‘drums2/000\_base.wav’, ‘drums2/001\_cowbell.wav’, ‘drums2/002\_clash.wav’, ‘drums2/003\_whistle.wav’, ‘drums2/004\_rim.wav’, ‘drums2/005\_hat.wav’, ‘drums2/006\_snare.wav’, ‘drums2/007\_clap.wav’] Traceback (most recent call last): File “[drumhat.py](http://drumhat.py)”, line 28, in alert\_pin=25) File “/usr/local/lib/python3.2/dist-packages/cap1xxx.py”, line 239, in **init** self.i2c = SMBus(i2c\_bus) IOError: [Errno 2] No such file or directory Exception AttributeError: “‘Cap1188’ object has no attribute ‘alert\_pin’” in \\> ignored ---

Did you enable i2c? ``` curl -sS get.pimoroni.com/i2c | bash ``` ---

I enabled it via raspi-config, but on running the script you suggested I get: I2C Already Enabled Adding i2c-dev to /etc/modules Adding i2c-bcm2708 to /etc/modules And, that does the trick! Thank you very much RogueM! Paddy ---

Great (though I’m not sure why you had trouble earlier)! ---

Hi, I’m doing something wrong, haven’t worked out what with Drumhat. Have enabled i2c and I know the speaker works as I’ve swapped over with my piano hat. When I try drum sounds I get lights on the Drumhat but no sound. I’ve tried it on Pi3 and Pi2. I’ve shutdown to add the hat before rebooting :) Any ideas appreciated. ---

what are you using to produce sounds?
