WeAct Epaper & Pico2

[SoberMindedDenis]

Hello. This is my first time working with displays and I can't figure out the sources of relations.
I found an example of such a file from Waveshare Pico LCD 2", but there is another relation "from drivers.st7789.st7789_4bit import". On Git, Adafruit_ssd1680 only has examples, but no driver, so "from epaperdisplay import EPaperDisplay" also leads nowhere. The only thing I understand is that the driver is in the author's drivers/epaper/epd29_ssd1680.py , when launched the console returns "MPY: soft reboot", but nothing happens - is this correct?

In the code translated by the author, the code refers to color_setup.py - if I understand correctly, this is not a screen driver, but a manifest containing the pin ratio on the board?
Probably I need color_setup.py for pi pico 2 + WeAct Epaper, as a layer between driver and main image output code? Can you help me and other newbies?

The WeAct Stdio ePaper 2.9" is supported - see driver details. Please install nano-gui as per the docs. You will need to write a color_setup.py file to define your wiring and to specify the SSD1680 display driver (not st7789).

Thanks for the answer. I have nano-gui installed and have read all the documentation, but I still don't understand the contents of the color_setup.py file. This, for example, doesn't work:

from mashine import Pin, SPI
from epd import EPD
spi = SPI(0)
cs_pin = Pin (26)
dc_pin = Pin(27)
res_pin = Pin(28)
busy_pin = Pin(29)
display = EPD(spi, cs=cs_pin, dc=dc_pin, res=res_pin, busy=busy_pin)

You are missing the definition of EPD.

Please use this file as a template. Note that the code initialises output pins with a value, also that the reset pin is specified by a pin no., not a Pin instance.
