Problems with 1.3" Oled

Other Hardware Displays
1

Hi everyone

Just starting out with the NodeMCU board, and trying to use the 1.3" OLED display, but I'm, having trouble with getting it to work.

I've downloaded the esp8266-oled-ssd1306 library (for Arduino) and try to use the examples with no luck. I use the following connections and initialize the display using the SSD1306Spi function:

// D5 -> CLK
// D7 -> MOSI (DOUT)
// D0 -> RES
// D2 -> DC
// D8 -> CS
SSD1306Spi display(D0, D2, D8)

.. but the display only outputs rubbish:

I'm kinda stuck here Any hints on how to proceed? :slight_smile:

(I have tried with more boards and displays with the same result)

Just tried the Adafruit SSD1306 library .. with similar results (see video).

Got it working .. switched to the u8g2 library and used the U8G2_SH1106_128X64_NONAME_1_4W_HW_SPI constructor. :slight_smile:

Did you drink what was in the glass before or after you got it working?

Before .. I wonder it that was the actual cause for my problems. :wink:
