Can you please provide a wiring diagram for using on an Arduino or ESP32

[Corruptsector]

I have tried to connect, but the pins are labeled for i2c, but a lot of the other example are SPI.

Can i use SPI to interface with this board?

[WeActStudio]

Yes, it only support spi

[fourgood]

But WHY are the pins labeled for i2c, if the display only supports SPI ???

[tursoe]

Yes, a wiring diagram would be nice.
It's easy to find out yourself, but faster if a diagram was provided for both ESP32 and Arduino Uno.

I need it for ESP8266 (sry for hijacking this thread)

Did you get it working?

Im trying to get working with ESPHOME. I tried using SDA as MOSI and SCL as CLK, but no joy.

spi:
  clk_pin: GPIO016
  mosi_pin: GPIO017

display:
  - platform: waveshare_epaper
    cs_pin: GPIO018
    dc_pin: GPIO021
    busy_pin: GPIO034
    reset_pin: GPIO033
    model: 2.13in-ttgo-b73
    full_update_every: 2
    lambda: |-
      it.print(0, 0, id(roboto), "Hello World!");

[Corruptsector]

I think:
SDA = data = MOSI
SCL = clock = SCK

I doubt this will work... while the the display I think at base is the same (gooddisplay) things are different... did you get the display working with the esp32 example? I have a similar issue see #2

also I suggest to try as model 2.13in-ttgo-dke this seems to match the number that weact is using.

you can check the example folder and the lib for the exact numbers https://github.com/ZinggJM/GxEPD2

No Sorry i didnt. It showed my hello world, but then started flashing and showing heaps of noise. So i guess my pinout is correct, but this model didnt work in ESPHOME

Im tried all the models in ESPhome without any luck. But ill try again.

indeed that indicates the screen is working. a link to the example you tried and the pinout you used will be useful. also to double check you are using bw only model.
i am in the same boat as you but mine does not even turn out

[alinelena]

the pinout from the esp32 example is

|epd | esp32|
VCC VCC
GND GND
SDA(MOSI) 23
SCL(SCK) 18
CS 5
D/C 0
RES 2
BUSY 15

Does it work with raspberry pi? I could not make it work with waveshare 2.13 display python code. Can you please help?

[MarAlMe]

I made an wiring diagram for an esp8266 (wemos d1 mini v4) and an esp32-s2 (wemos d1 mini). The VBUS is 5V.

// ESP8266 CS=15,SCL(SCK)=14,SDA(MOSI)=13,BUSY=16,RST=5,DC=4

// ESP32-S2 CS=34,SCL(SCK)=36,SDA(MOSI)=35,BUSY=3,RST=9,DC=38

[OperatorB]

Thanks for the wiring diagram! By the way what tool do you @MarAlMe use to make this pretty diagram above, it looks amazing?

[MarAlMe]

Thank you @OperatorB, its just Gimp 😎
