My e-ink frame

Matuki

@MajorC
Hello,
The left panel is the default weather module with minors modifications that can be found on the repository: https://github.com/seb-ma/eInkFrame/blob/master/magicmirror_files/patches/MagicMirror.patch

And the chart on the right is the module I made and shown here: https://forum.magicmirror.builders/topic/17604/mmm-weatherchartd3

Both of them rely on modifications I made on weather provider to retrieve pollution (only openweather is currently supported). And I also did another modification on openweather provider to fetch all data once instead of having multiple calls to the API.

Finally, I also did a module that acts as a proxy to weather provider to avoid a call to weather API each time a module wants data (openweather and others are limiting the number of calls by day, thus this helps having more updates without reaching the limit): https://github.com/seb-ma/mmm-weatherproviderunique

Thank you. Then I will try the components next time.

@Matuki Thank you for sharing. I’m in the process of doing something similar: your code is a godsend!

nat.andrews

perfect github page, thank you a lot!

I’m following your instructions, but can’t see the step where we get Magic mirror to display on the e-ink panel.
setting resolution etc. am I missing a step?

@nat-andrews hello,

The display is done by the module I wrote: https://github.com/seb-ma/MMM-IT8951

The configuration is done like any module: https://github.com/seb-ma/eInkFrame/blob/4defe289e4ebbc873d0e68418e278ff21a976e08/magicmirror_files/config.js#L81

And the resolution is automatically found when initializing driver.
It can be forced in config file when using mock for tests: electronOptions: { fullscreen: true, width: 1872, height: 1404 }

Be sure to set the correct value of VCOM to not damage your eink.
Also, I never had success running my module without the root user. So, unless you find a way (this interest me) you must run MagicMirror as root.

I let you read the readme of the MMM-IT8951 module, but if you need more details or have some questions, let me know.

edited to correct behavior on resolution

@Matuki Thanks again for you help with this. I’m trying to get my eink working without the touch pads.

Can I confirm how you run the mirror as root? Just using sudo? Also the VCOM needs to be given to the MMM-IT8951 module as “driverParam: { VCOM: -1.25 },” in the config? I didn’t see anything about this in the instructions.

Thanks!

@Matuki Also just wondering what version of nodejs you need and why? Just checking whether I need a new version of nodejs or if RPi distribution has caught up?
