Hello,
InkyPHAT examples are not reporting any problem, yet the display is not updated. When I put in an old card with Debian Jessie, it works fine (so it’s definitely not hw-related). Can you please advise what else to check?
Pi Zero, updated Raspbian Buster image, SPI is enabled
OK so for some reason the newer inky library and examples (curl https://get.pimoroni.com/inky) is not working at all - tested it with 3B+ too. What fixed the problem for me was installing inkyphat (curl https://get.pimoroni.com/inkyphat | bash) thus I am very grateful it still exists.
