Library does not work with Feather S2 and Circuit Python 6.x

[jdoscher]

Using the guide from Adafruit here:
https://learn.adafruit.com/adafruit-eink-display-breakouts/grayscale-29-overview

The code returns the following error:

code.py output:
Traceback (most recent call last):
  File "code.py", line 26, in <module>
  File "adafruit_il0373.py", line 184, in __init__
TypeError: extra keyword arguments given

The offending code is this section, with line 26 the first line here:

display = adafruit_il0373.IL0373(
    display_bus,

What version of CircuitPython are you using? Please try the absolute latest version. It adds a grayscale kwarg to EInkDisplay which this library uses.

[jdoscher]

Adafruit CircuitPython 6.0.0-rc.0-4-g3c05a8c68 on 2020-10-17; FeatherS2 with ESP32S2, the latest that I am aware of. The argument for grayscale is in the above code as well.

@jdoscher on circuipython.org downloads page under the "absolute newest" section you can click "Browse S3" to get to a listing of all of the built images. Even newer ones than the newest released version. Here is a link to the S3 page for FeatherS2: https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/unexpectedmaker_feathers2/en_US/

Using the same sample code and the latest CP 6.x from today (11/10) and the latest libs from today (11/10) I still get the same error:

Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.

Press any key to enter the REPL. Use CTRL-D to reload.

I think this is something with the Feather S2 build. I don't have any other boards to test on.

Edit:
I am using:
adafruit-circuitpython-unexpectedmaker_feathers2-en_US-20201110-61bf0e9.bin for the Feather S2
adafruit-circuitpython-bundle-6.x-mpy-20201110 for the libraries

[makermelissa]

I tested this with the FeatherS2 and GrayScale FeatherWing and got the same result:

Traceback (most recent call last):
  File "code.py", line 26, in <module>
  File "/lib/adafruit_il0373.py", line 184, in __init__
TypeError: extra keyword arguments given

The same code runs great on the MagTag.

[tannewt]

I'm going to move this to circuitpython because it appears to be a weird, board-specific issue.

[skieast]

I've been using a FeatherS2 with the Adafruit 2.9" Grayscale successfully using very similar code.
My setup looks like this

# these are for the FeatherS2
epd_dc = board.IO3
epd_cs = board.IO1

displayio.release_displays()
display_bus = displayio.FourWire(board.SPI(), command=epd_dc,
                                 chip_select=epd_cs,
                                baudrate=1000000)
time.sleep(1)
display = adafruit_il0373.IL0373(
    display_bus,
    width=296,
    height=128,
    rotation=270,
    black_bits_inverted=False,
    color_bits_inverted=False,
    grayscale=True,
    refresh_time=1,
    seconds_per_frame=5
)

The code is basically the same as the Magtag Countdown code except for the pin changes to accomodate the FeatherS2

[dhalbert]

I tested this with a FeatherS2, CircuitPython 6.2.0-beta.3, and the latest adafruit_il0373.mpy. There were no errors.

One thing that I have seen is that a stray copy of a library is left in / on CIRCUITPY instead of in lib/. sys.path is set so that / searched before lib/. Also, any .py version of a file takes precedence over a .mpy version, so if both were available, you might have gotten an older version of the library.

I will close this for now but please reopen if you can reproduce with the latest and with a clean filesystem.
