Pianohat

Support

Hi,
i have a question relating to piano hat. I 've just put a new rpi installation with the newest jessie. Put piano hat, enabled i2c, but every time I try to run simple-piano.py I get an error:
This script requires the pygame module
Install with: sudo pip install pygame

When I try to install pygame I got :
Looking in indexes: Simple index, piwheels - Simple index
Requirement already satisfied: pygame in /usr/lib/python3/dist-packages (1.9.6)

so I have pygame for python3… but still cannot run piano hat… can You help me ?

Regards,
mike

You could try running the example with python3 simple-piano.py to specify that you want to use Python 3? I suspect you might run into other problems using an OS as old as Jessie though.

Thanks,

should I change Jessie ? what’s your recommendations ?

Mike

You can download and flash the most recent Raspberry Pi OS image using Raspberry Pi Imager:

will do. Shouldd it help with missing mixer lib libSDL2_mixer-2.0.so.0?

Running an up to date OS may well sort your missing dependencies, but I found this post that contains some things you could also try: python - Pygame: ImportError: libSDL_ttf-2.0.so.0: cannot open shared object file: No such file or directory - Stack Overflow
