HINK-E075A07-A0 7.5inch 880x528 e-ink display with esphome - blank display

ld9000 · December 29, 2025, 4:29am

Hi there

I just got one of these https://www.aliexpress.com/item/1005008096259306.html
( HINK-E075A07-A0 7.5inch 24Pin 880x528 e-Paper E-ink raw Display Red Black White )

Along with a https://www.aliexpress.com/item/1005009827197743.html ( Waveshare e-Paper ESP32 Driver Board Rev 3 )

Hooked it all up, and configured the GPIOs according to the image on the waveshare site

However I am getting zero reaction out of the e-ink display.

This e-ink display is 7.5" however the resolution is 880x528 pixels - the waveshare site for the driver board doesn’t list this res. With some google-fu I found I can use “generic SPI” to drive this display:

esphome:
  name: esp32-eink-1

esp32:
  board: esp32dev
  framework:
    type: esp-idf

logger: 
  level: VERBOSE

api:
  encryption:
    key: "redacted"

ota:
  - platform: esphome
    password: "redacted"

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

captive_portal:

font:
  - file: "fonts/menlo.ttf" 
    id: font_menlo
    size: 32

spi:
  clk_pin: GPIO13
  mosi_pin: GPIO14

display:
  - platform: epaper_spi
    model: SSD1677        # Via https://esphome.io/components/display/epaper_spi/
    cs_pin: GPIO15
    dc_pin: GPIO27
    reset_pin: GPIO26
    busy_pin: { number: GPIO25, inverted: False, mode: { input: True, pulldown: True } }
    dimensions:
      width: 880
      height: 528
    full_update_every: 1
    update_interval: 10s
    lambda: |-
      it.fill(Color::WHITE);
      it.print(0, 0, id(font_menlo), Color::BLACK, "HELLO WORLD!");

But I got no reaction from the display; so and get this in the logs:

I am assuming the esp32 is able to transmit the display data to the display (Or else I would expect there would be some errors?) But I have no reaction from the display at all (it’s totally “white”, i.e. how it looked when it was shipped to me).

I’ve searched for people using this specific display, but I’ve come up short - however, I assumed this is like many other things HomeAssistant - close enough that it’ll work but this time, that appears to not be the case.

Any guidance on how to get this going would be appreciated!

Did you try the Waveshare demo code to verify your devices are working?

ld9000 · December 29, 2025, 10:11am

I found the issue… I had a loose connection. Its working now. Here is the code I’m using:

font:
  - file: "fonts/menlo.ttf" 
    id: font_menlo
    size: 32
  - file: "gfonts://Open Sans@700"
    id: font_os_bold
    size: 32
  - file: "gfonts://Montserrat@800"
    id: font_montserrat
    size: 32
  - file: "gfonts://Bitter@900"     
    id: font_bitter
    size: 32

spi:
  clk_pin: GPIO13
  mosi_pin: GPIO14

display:
  - platform: waveshare_epaper
    update_interval: 600s
    cs_pin: GPIO15
    dc_pin: GPIO27
    busy_pin: GPIO25
    reset_pin: GPIO26
    model: 7.50in-hd-b
    lambda: |-
      it.print(10, 20, id(font_menlo), "The quick brown fox jumps over the lazy dog");
      it.print(10, 80, id(font_bitter), "The quick brown fox jumps over the lazy dog");
      it.print(10, 140, id(font_montserrat), "The quick brown fox jumps over the lazy dog");
      it.print(10, 200, id(font_os_bold), "The quick brown fox jumps over the lazy dog");

Only thing is I haven’t figured out how to draw in red colour

Karosm · December 29, 2025, 10:36am

Docs have example for that

lambda: |-
  const auto BLACK   = Color(0,   0,   0,   0);
  const auto RED     = Color(255, 0,   0,   0);

  it.print(100, 100, id(font1), RED, "Hello World in red!");

ld9000 · December 29, 2025, 10:57am

Yes I tried that:

font:
  - file: "fonts/menlo.ttf" 
    id: font_menlo
    size: 32

spi:
  clk_pin: GPIO13
  mosi_pin: GPIO14

display:
  - platform: waveshare_epaper
    update_interval: 600s
    cs_pin: GPIO15
    dc_pin: GPIO27
    busy_pin: GPIO25
    reset_pin: GPIO26
    model: 7.50in-hd-b
    lambda: |-
      const auto BLACK   = Color(0,   0,   0,   0);
      const auto RED     = Color(255, 0,   0,   0);
    
      it.print(10, 260, id(font_menlo), RED, "Hello World in red!");

Unfortunately it comes up in B/W:

Karosm · December 29, 2025, 11:05am

try to flip the dip switch a/b and repower the board.
