    I got an 1306 128x64 OLED (Waveshare).
    A line like
    diagonally covers the whole screen, so it appears that the y-axis in B4R is only 32 pixel wide.
    The Adafruit library supports 128x64 and 128x32 displays.
    Is there a choice in B4R for those display types?

    You need to edit Adafruit_SSD1306.h.
    // #define SSD1306_128_64
    #define SSD1306_128_32
    // #define SSD1306_96_16

    #define SSD1306_128_64
    // #define SSD1306_128_32
    // #define SSD1306_96_16

    Thank you, that worked.
    Yesterday night I had tried that with the Arduino IDE, but it did not work. The Nodemcu apparently got more and more petulant and I stopped working.
    This morning I had changed the USB cable to a "thicker" one. I hope the reliability becomes (and stays) better.
    Though finally not a big project, I will post it when finished (graphing BMP280 data on OLED).
