I’m having an odd issue with my new Inky pHAT Yellow, ordered from Adafruit due to being a US tinkerer. Unfortunately it seems whenever I use the included code from Pimoroni and specify the display as yellow, I get this incredibly dark result that’s VERY low-contrast, like so:
But on a whim after testing and running the
clean.py script a few times, I decided to try using the ‘red’ setting, just in case. It’s not perfect, but at least better? It’s still only more of a contrasting grey than a real yellow without very bright lighting.
Now with both of these I was shining a bright LED light directly on them. The contrast is even worse in regular light, nowhere near the contrast shown in the photos of the product on the website. Is my Inky pHAT defective? This is using a Pi Zero W with 1A power. I’m concerned because I wanted to be able to use this with a LiPo SHIM for use in a convention, with timed rotation of the panel every say 30 minutes or with a button SHIM soldered to the bottom of the pi to allow swapping displays (assignable via a bottle app over wifi AP). Or am I better off switching to a red one instead?
