I managed to install the micropython-ssd1327-1.0.0 library,according to  
this:
  https://www.raspberrypi.org/forums/viewtopic.php?t19%1744
but after adding: import ssd1327
it returns

File "build/bdist.linux-armv6l/egg/ssd1327.py", line 5, in <module>
ImportError: No module named micropython

Have I missed something.

Oops, a bit vague above.
I am trying to install the ssd1327 driver for a oled display.
Adafruit's library file won't install because

This library is not available on PyPI yet. Install documentation is  
included as a standard element. Stay tuned for PyPI availability!

So then I found the same driver file for micropython, but I get the  
above error when I import the said ssd1327 in a python script.

    But did you also install /micropython/ itself?

... and if you did, are you invoking it? Micropython is not a module for
regular Python, it is a separate limited language interpreter optimized for
use on microcontrollers.

    A search for "ssd1327 raspberry pi" leads to
https://luma-oled.readthedocs.io/en/latest/intro.html


FYI: from what I can tell, if the Adafruit library
https://github.com/adafruit/Adafruit_CircuitPython_SSD1327/releases/tag/1.0.0
can be used, you'll have to install the Adafruit blinka library to provide
the CircuitPython interface API.

    As for the lack of PyPi availability...

Ok, my apologies, as I could NOT install the micropython-ssd1327-1.0.0  
library because after I DID install micropython from here:

https://www.raspberrypi.org/forums/viewtopic.php?t19%1744

I received the said error about no module called micropython

No I did not invoke as I didn't know that it had to be
Quoted text here. Click to load it

It looks like the Adafruit_CircuitPython_SS1327 library can't be  
installed then, and the micropython-ssd1327-1.0.0 library can't be used  
due to micropython not being invoked???

It now seems that the said oled display can't be used with a raspberry  
pi, as it needs the ssd1327 library.

Thanks

    Okay, if you built micropython, and the test (section 4) runs, I'd
think the next move would be to follow step 5 to install the micropython
package.

Quoted text here. Click to load it
    The Adafruit library requires /displayio/ but on Linux the
adafruit_blinka interface library only provides  

"""
This repository contains a selection of packages mirroring the
CircuitPython API on hosts running micropython. Working code exists to
emulate the CircuitPython packages;

    board - breakout-specific pin identities
    microcontroller - chip-specific pin identities
    digitalio - digital input/output pins, using pin identities from
board+microcontroller packages
    bitbangio - software-driven interfaces for I2C, SPI
    busio - hardware-driven interfaces for I2C, SPI, UART
    time * - substitute functions monkey-patched to time module
"""
... No displayio (nor many of the libraries shown
https://circuitpython.readthedocs.io/en/4.x/shared-bindings/index.html )

    Micropython requires you to invoke it explicitly:

    Looks to me like the display is feasible (the usage page didn't list
the 1327, but imported 1306, 1309, 1325, 13331, and sh1106 -- I took a
chance specifying 1327, and it took without error) {I've now uninstalled
since, as stated, I don't have the display, so why clutter SD card}

    Obviously, you'll need to follow the luma.oled API to use the display.

Thanks for that.
I already had some of the files installed from a previous attempt.
In the luma.examples/examples folder, I edited the clock.py script to  
include:

from luma.core.interface.serial import i2c, spi
from luma.core.render import canvas
from luma.oled.device import ssd1306, ssd1309, ssd1325, ssd1331, sh1106

but edited the last line to just
from luma.oled.device import ssd1327.

When I ran the script :
pi@raspberrypi:~/luma.examples/examples $ python clock.py
Version: luma.oled 3.3.0 (luma.core 1.12.0)
Display: ssd1306
Interface: i2c
Dimensions: 128 x 64

and there was no errors and nothing on the display.

    Sorry -- we are now beyond what I can investigate (no display here with
which to test).
