J2 -> pos 2 for SPI serial interface
for this to work the modified U8g2 Library has to be used: https://github.com/morlac/U8g2_Arduino
NodeMCU:
#define DISPLAY_RST D4 // RST pin is connected to NodeMCU pin D4 (GPIO2)
#define DISPLAY_CS D3 // CS pin is connected to NodeMCU pin D4 (GPIO0)
#define DISPLAY_DC D2 // DC pin is connected to NodeMCU pin D4 (GPIO4)
// initialize U8g2 library with hardware SPI module
// SCK (CLK) ---> NodeMCU pin D5 (GPIO14)
// MOSI(DIN) ---> NodeMCU pin D7 (GPIO13)

checkout the above mentioned library in the Arduino libraries folder
#define DISPLAY_RST 8
