Tried to start pydpiper manualy but:
Quote:A dependency job for pydpiper.service failed. See 'journalctl -xe' for details.
Something gone wrong with Docker, don't know can I just de-install it and install it again or mount a new image on SD card
You can uninstall and reinstall the docker. Post #53 in this thread for how to uninstall the docker.

After a few hours of uninstalling, reinstalling, rebooting...it is impossible to install Docker again. Will try to mount the image and do install Pydpiper from start for the 4th time

A combination between lcd i2c and winstar drivers maybe?
Hi. I want to help but I am not sure I understand your question. May be you can reformulate?
Small displays can use LCD or OLED technology.
OLED is a more modern technology. It has much better contrast and use less power.
LCD and OLED displays can connect to your RPi using parallel interface (16 wires), i2c interface (4 wires), SPI interface (6-7 wires).
On this forum you can find tutorials for using parallel, i2c and SPI interface.

I was not clear, my question is if it is possible to have a driver for oled with i2c.
Maybe I am wrong, but in pydPiper the driver for oled (winstar-ws0010) is for parallel interface.
The answer is in the first post of this thread and in the
pydpiper web site.

The 2.42-inch OLED in your picture above is the control chip of ssd1309, right? Can you also use the ssd1306 in the tutorial to drive it?
Hi. Yes mine is 1309. it will work with 1306 because in the pydpiper website dhrone says pydpiper is "Compatible with SSD1306 style displays (I2C only)". Not SPI.

Hi, I bought an OLED display 2.42 "SPI / I2C
128x64 can it be connected?

Hi,
It can be connected using SPI interface (default) or i2c if you can do some soldering as indicated on the board.
If you use it with SPI interface, you can follow
this tutorial by Rikardo. If you use the i2c interface, you can use
this tutorial instead.

And you can write which pins connect to the raspberry?
i2c

i2c
Display . RPi
SDA--------------- PIN 3
SCL---------------- PIN 5
VCC--------------- PIN 2 or 4
GND--------------- any ground PIN
