Thank you, @DJDevon3, for opening this issue! It was I (⚡️) who was having the issue!
It's true, that I was originally using adafruit_bitmapsaver.save_pixels()
, but upon further investigation, I can conclude that the root of the problem is likely the adafruit_displayio_sh1107
library (or displayio.Display
).
When using SH1107.fill_row()
(an extension of displayio.Display.fill_row()
) it triggers the following error:
ValueError: Display must have a 16 bit colorspace.
The display in question indeed has a 1 bit colorspace:
class SH1107(displayio.Display):
def __init__(...):
super().__init__(
#...
color_depth=1,
#...
I am not sure whether SH1107.fill_row() should override displayio.Display.fill_row() or if the Display method itself needs modification.
This looks like a core issue because it is a limitation of fill_row
: https://github.com/adafruit/circuitpython/blob/70ce576390c7b21007b1f75f16e6fc591c0f61d7/shared-bindings/displayio/Display.c#L479
I'll move the issue.
Someone was having an issue with taking a screenshot with a monochrome display due to bitmap colorspace. There doesn't seem to be support for monochrome displays?
They were using a 128x128 Monochrome display I do not have one to test with.
