[saikek]

Have you looked for this feature in other issues and in the docs?
Yes, docs (displays section) and forum (1 similar entry).

Is your feature request related to a problem? Please describe.
It would be great to support Nokia 5110 displays (SPI, PCD8544 platform)

Describe the solution you'd like
Either update documentation with correct DisplayModel for his platform, or add another one.

Describe alternatives you've considered
Not using display.

Additional context
This is 4-pin SPI display with 84x48 screen resolution and blue backlight.

Connection seems to be very much similar to this particular comment or issue

I've used following connection:

TFT Pin	Pin Name	Node MCU (Wemos) Pin	Tasmota Config
RST	Reset	RST	----
CE	chip select	D8 (GPIO 15)	SPI CS (66)
DC	Data/Command	D0 (GPIO 16)	SPI DC (67)
Din	Serial Data In	D7 (GPIO 13)	----
Clk	Serial Clock	D5 (GPIO 14)	----
Vcc	3.3 voltage	3.3V	----
BL	Backlight, 3.3V	D2 (GPIO 04)	Backlight (68)
GND	Ground	Ground	----

And in code I have un-commented all directives related to SPI. Howevr none of selected DisplayModels does not show any test on screen.

(Please, remember to close the issue when the problem has been addressed)
