• Please take a picture of your wiring and do a table like this:


    Display     NodeMCU     ESP-12   Colour
    LED         3V3         3V3       N/A
    SCLCK       D5          GPIO14    Green
    DN<MOSI>    D7          GPIO13    Yellow
    D/C         D2          GPIO04    Orange
    RST         D1          GPIO05    Brown
    SCE         D8          GPIO15    Red
    GND         GND         GND       Grey
    VCC         3V3         3V3       Blue
    BackLight   GND         GND       Purple

    As you can see here NodeMCU.D7 is gpio13

    I don't think your init it matching how you have wired up.
