Controlling flexible grayscale OLED from ESP-EYE?

Aside from it’s micro-USB port, the only electrical interface that the ESP-EYE provides is an SPI port with four pins: DOUT, DIN, CLK, CS

Shouldn’t that be sufficient to control the LCD-14606 Flexible Grayscale OLED Breakout?

Connections for testing:

  • - ESP-EYE **CS**: OLED **C̅S̅**
  • - ESP-EYE **CLK**: OLED **SCLK**
  • - ESP-EYE **DOUT**: OLED **S̅D̅I̅N̅**
  • - USB **5V** / **GND**: OLED **VIN** / **GND**

    • In addition, I tried connecting ESP-EYE DIN to OLED RES. Then I tried all combinations between connecting ESP-EYE DIN / DOUT and OLED S̅D̅I̅N̅ / RES.

    However, it just doesn’t work. There is no image on the display.

    Attached is the code that I uploaded to the ESP-EYE using the Arduino IDE. Note that I had to make a small tweak to the OLED library so that it finds pgmspace.h.

    After adjusting csPin and resPin, this code works perfectly well with an Arduino Uno and the OLED display. This means I get an image on the display with an Arduino Uno.
