Help for use

Hello,
Sorry for the translation I use google translate.

I have a raspberry pi4 with the latest version of the Magic Mirror.
It works perfectly.

I bought a 7.5inch waveshare eink screen (monochrome, V2, 800 * 400).
I manage to run the waveshare demo code on the screen without worry (python epd_7in5_V2_test.py)

But impossible to have the magic mirror on the eink screen
i @ raspberrypi: ~ / rpi-magicmirror-eink $ pm2 start index.js --name "eink-update"
[PM2] Applying action restartProcessId on app [eink-update] (ids: 0)

The eink screen remains desperately white
Can you help me ?

Hello,

Solution provided by Silvio on the site of the author of this project:

Installation supplement for V2 display (resolution 800 × 480):

The following steps are still necessary for the instructions above.

Copy epd7in5_V2.py to "rpi-magicmirror-eink / ePaperPython" (source)
epdconfig.py after "rpi-magicmirror-eink / ePaperPython" - is also in the above-mentioned source
Change the following information in the epd7in5_V2.py file: “from. import epdconfig "to" import epdconfig "(line 32)
in main.py (rpi-magicmirror-eink / ePaperPython) replace line "epd.display_frame (epd.get_frame_buffer (image))" with "epd.display (epd.getbuffer (image))"
in the rpi-magicmirror-eink / ePaperPython / main.py
each "epd7in5" must be replaced with "epd7in5_V2"
Adjust the resolution to 800 × 480 in config.js (folder: rpi-magicmirror-eink)
