Add support for Inky pHAT and wHAT

[CapnBio]

Release version = 2.0.0 Expected behavior = e-ink display to update with modules Actual behavior = upon start up OS works fine, no update on display Steps to reproduce the behavior = before installation input all things needed for installation and inky wHAT is already connected

I am trying out this code today and it is not working out of the box after installation with the Inky wHAT with a 4.2 in e-ink display.

I have not tried out the pHAT since it is a smaller 2.13 in screen.

Hi there @CapnBio and welcome to Inkycal! Thanks for opening your first issue in this repo 💯 Please note that the epd-displays from pimoroni are not officially supported by Inkycal (see supported displays, hence they cannot be used with Inkycal (yet). Technically it uses the same drivers as the waveshare 4.2" black-white-red or black-white-yellow display, but it will require some testing at least. Fortunately, I do have a black-white-red Inky what so it shouldn't take more than a few days.

I'll leave this issue open until then. And yes, smaller displays don't serve good as full dashboards, hence bigger displays (4.2"<) are preferred for Inkycal. The largest supported display is the 12.48" available in black-white / black-white-colour :)

Thanks lots for your support @aceisace I super appreciate it!

@aceisace so how were your trials?

Will get back to it this weekend 😅

I have an inkyWhat (yellow) I can try it out if you can point to where I can look to get started? (Otherwise I'll browse around and see if I can figure it out)

I tried a few different drivers and nothing happens on the inkyWhat for any of them. A quick (naive) browse of the inky project looks like their drivers are doing I2C as well as SPI, but otherwise I can't really compare the two driver parts well atm.

I was considering just importing inky (https://github.com/pimoroni/inky.git ) project and wrapping it with the driver calls as a new display type.

I've created a branch for this issue as the support for this display is unfortunately not as straight-forward as the pinout is different. I'm pretty sure the drivers are pretty similar with the 4.2" one from waveshare. Next weekend I will have some time to test this display with my pi4. I'll post an update after running some tests :+1:
