I'm not sure, but I don't think so. I put my code on github here so you can see what I'm doing.

I initially took the code from Adafruit, but since this library uses a different implementation for SPI (and I2C) I modified it to work on the pine64.

Nokia5110.py is my modified library.
nokia_test2.py draws some shapes and text on the display.
nokia_clock2.py draws a very simple analog clock.

Can you pastebin the debug output you see on your console?

sure here's a snippet of it:

Code:
tx[0]=00
tx[1]=00
tx[2]=00
tx[3]=00
tx[4]=00
tx[5]=00
tx[6]=00
tx[7]=00
tx[8]=00
tx[9]=00
tx[10]=00

It looks like whatever is being sent over SPI is also being dumped to the screen. I'd like to be able to turn this off, as it makes it difficult to find anything else that I try printing.

I endeavored to introduce it. Amid the establishment, it gived to me a blunder: 

"Python.h can't discovered record or catalog" 

I am certain to have Python introduced, in such a case that I express "python" in terminal, it returns me the adaptation

Has there been any change in this of late? I'm trying to resurrect some old python2 code on my pine64s (and port it to python3) but installing via library by cloning the repo and doing a `sudo python setup.py install` on a fresh build of Manjaro ARM is getting me the dreaded errror:
Code:
Traceback (most recent call last):
  File "./pine64-fan-control.py", line 9, in <module>
    from RPi import GPIO as GPIO
  File "/usr/lib/python3.8/site-packages/RPi/GPIO/__init__.py", line 23, in <module>
    from RPi._GPIO import *
RuntimeError: This module can only be run on a Raspberry Pi!

Idealy I'd install it in a venv, but I'm not that far yet, and I've not installed the 'official' RPI version, so basically no idea what's going on now!

I am also interested if anyone ever got event detection (interrupts) to work and if so what modificaitons were made to the dts to enable this?

I am looking for steps to download and install RPi.GPIO on my Pine64 A64. For some reason my original SD card and steps from 2016 are missing and my SD card is corrupt. This is possibly why it was moth-balled. BUt I am revisiting and have Armbian image installed and have HDMI and LCD, WIFI and BT working. Now I'd like to get this SBC to control a Robot. I could not get RPi.GPIO or Wiring to install

Hi all,
i've the following error when I try to install RPi.GPIO-PineA64 via command sudo python3 setup.py install:

Can anyone helps me to find out the solution?

Well, it seems to me that such manuals are already completely outdated.
