Hi, I have a serial LCD that has SPI communicatio. I search the internet for connecting it with arduino Leonardo and I dont understand at all. My serial LCD has 8 pins. That are, 5v, Gnd, Vo for contrast, E for enable signal, S/D for SPI, CLK for serial clock, and backlight pin (-) and (+). Where should I connect E, S/D, and CLK pins to arduino leonardo? This is my specification for my serial LCD.
