PyGlow is a Python library to help drive the LEDs on an Pimoroni PyGlow hat for the Raspberry Pi
Python module for PiGlow board for RPi
You’ll need python-smbus and some other stuff. Please see
https://github.com/pimoroni/piglow#setting-up-your-raspberry-pi
Enable i2c drivers
sudo -e /etc/modules
Then ensure you have the following in there:
i2c-devi2c-bcm2708
You may also need to check these drivers aren’t blacklisted:
grep bcm2708 /etc/modprobe.d/raspi-blacklist.conf
If spi-bcm2708 or i2c-bcm2708 are there, comment them out.
Next up, install i2c libs and Python support:
sudo apt-get install python-smbus
Finally, reboot your RPi.
sudo shutdown -r now
