I have an OLD display SSD1306 128x64 0.96 inch
and an ESP32 (DEVKIT V1 TyPEC)

I’ve already been able to do a lot with it.
But the OLED display shows nothing.
My YAML code is valid and can be installed.
The connections on the display and board all appear to be correct.
What could that be?

The YAML code sequence used is:

Example configuration entry

i2c:
sda: 21
scl: 22
font:

  • file: “Roboto-Regular.ttf”
    id: my_font
    size: 16

display:

  • platform: ssd1306_i2c
    #model: “SH1106 128x64”
    model: “SSD1306 128x64”
    #reset_pin: 23
    address: 0x3C
    lambda: |-
    it.print(0, 0, id(my_font), “Hello World!”);
