Waveshare 3in7 errors

[ZubaZ21]

I think the Waveshare 3in7 drivers are non-standard . . . and it's causing the movie not to play. The display isn't being cleared at all.
Describe the problem

pi@GeneralPie:~/Projects/SlowMovie $ python3 slowmovie.py -o DEBUG
Picking which video to play...
...trying the --file argument...
...trying the video in the nowPlaying file...
...picked '/home/pi/Projects/SlowMovie/Videos/test.mp4'!
Update interval: 120
Frame increment: 4
Playing 'test.mp4'
Video info: 50 frames, 24.125fps, duration: 00:00:02
This video will take 25.0 minute(s) to play.
Traceback (most recent call last):
  File "slowmovie.py", line 322, in <module>
    epd.init()
TypeError: init() missing 1 required positional argument: 'mode'

I changed the line to match the waveshare demo script : epd.init(0)

Ran it again

pi@GeneralPie:~/Projects/SlowMovie $ python3 slowmovie.py -o DEBUG
Picking which video to play...
...trying the --file argument...
...trying the video in the nowPlaying file...

Traceback (most recent call last):
  File "slowmovie.py", line 342, in <module>
    epd.display(epd.getbuffer(pil_im))
AttributeError: 'EPD' object has no attribute 'display'

At this point I don't know what to tweak or where to look for what to tweak.

This is the second project that didn't run out of the box as expected.

You are correct - the 3in7 display has some different methods than the standard devices. It takes some additional parameters as part of init() and has some different display methods as well. We're currently working on a solution to handle non-standard displays - hopefully ready soon.

Rock on!

Thanks

Seems like they never do

@ZubaZ21 - you should be able to follow the instructions and use your 3.7 in display now. Lookup the display name to use in this table: https://github.com/robweber/omni-epd#displays-implemented

I love the idea of abstracting this. Very cool. Pulled it down and ran the test util. It threw an error. File "/usr/local/lib/python3.7/dist-packages/omni_epd/displays/waveshare_display.py", line 251, in prepare self._device.init() TypeError: init() missing 1 required positional argument: 'mode' I added a 0 so it became self._device.init(0) as that is what the waveshare driver requested. Fired it off again and got the following. pi@GeneralPie:~ $ omni-epd-test -e waveshare_epd.epd3in7 Loaded waveshare_epd.epd3in7 with width 280 and height 480 Drawing rectangle of width 210.0 and height 360.0 Drawing rectangle of width 105.0 and height 180.0 Drawing rectangle of width 26.25 and height 45.0 Traceback (most recent call last): File "/usr/local/bin/omni-epd-test", line 10, in <module> sys.exit(main()) File "/usr/local/lib/python3.7/dist-packages/omni_epd/test_utility.py", line 127, in main test.draw() File "/usr/local/lib/python3.7/dist-packages/omni_epd/test_utility.py", line 85, in draw self.__draw_on_display(im) File "/usr/local/lib/python3.7/dist-packages/omni_epd/test_utility.py", line 67, in __draw_on_display self.epd.display(image) File "/usr/local/lib/python3.7/dist-packages/omni_epd/virtualepd.py", line 202, in display self._display(self.__applyConfig(image)) File "/usr/local/lib/python3.7/dist-packages/omni_epd/displays/waveshare_display.py", line 263, in _display self._device.display(self._device.getbuffer(image)) AttributeError: 'EPD' object has no attribute 'display' Let me know if you need further testing.

Thanks for testing this - I'm going to move this over to the omni-epd repo since it's more of an issue with that.
