I am trying to use the Pimoroni IO Expander with the Hyperpixel 4 Sq on a Raspberry Pi 3A+. I have ran this script:
sudo ln -s /dev/i2c-3 /dev/i2c-1. However I get this error:
No such file or directory: '/dev/i2c-1'. I think its because the symlink isn’t working correctly and I don’t know how to rectify it. Any help would be appreciated!
