2.9 inch E-Paper Display and wemos d1 mini don't work

[502...@gmail.com]

Hi all, 

Just got 2.9 inch E-Paper Display (https://aliexpress.ru/item/4001279382105.html?spm=a2g0s.9042311.0.0.264d33edC9DgvO&_ga=2.9916092.888654037.1606053452-528014183.1595542930)

and connect it to wemos d1 mini. 

WEMOS <-> DISPLAY
3,3 <-> VCC
GND <-> GND
D7 (13) <-> SDI
D5 (14)   <-> CLK
D2 (4) <-> CS  

D1 (5) <-> DC   

D6 (12) <-> reset

Compile 9.1 with USE_DISPLAY, USE_I2C, USE_DISPLAY_MODES1TO5 , USE_DISPLAY_EPAPER_29   

 

Set template: 

and 

DisplayMode 0
DisplayModel 5 (it's applied) 

And no any reaction on "DisplayText [s1l1c1]Hello how are you? " command. 

Any ideas what is wrong?

I ran

displaytext [zOa2f0s2l1c1]Test 1 2 3

on my display (not e-paper) and that worked. I put zO at the beginning to turn the display on. 

Also set displaydimmer 100

in case it is dimmed too low to display anything.

I have no issues with oled like this https://aliexpress.ru/item/32801063529.html?spm=a2g0s.9042311.0.0.264d33edZ9V4DX&_ga=2.77103516.888654037.1606053452-528014183.1595542930

But  E-Paper still doesn't work for me  (.

Hi 502,

I have a similar model of display from Ebay and I also failed to get it working with TASMOTA.

I figured out two things, this display  https://aliexpress.ru/item/4001279382105.html?spm=a2g0s.9042311.0.0.264d33edC9DgvO&_ga=2.9916092.888654037.1606053452-528014183.1595542930 

is may a three color one (mine has red, black and white)

So that is different from the waveshare 2.9 Inch b/w modul  https://tasmota.github.io/docs/Displays/ tells:

######

USE_DISPLAY_EPAPER_29
Enable Waveshare EPAPER_29 display.(black/white, partial update)
Also requires USE_SPI

#####

Also:

https://www.waveshare.com/wiki/2.9inch_e-Paper_Module

Tells that there is a new and an old module that look similar but behave different ....

So may sombody can check that on driver level.
