  • Hi! I guess it's this one? https://uk.banggood.com/1_8-Inch-LCD-Scr­een-SPI-Serial-Port-Module-TFT-Color-Dis­play-Touch-Screen-ST7735-p-1414465.html?­cur_warehouse=CN

    If so:

    Number	Name	1.8 inch TFT LCD
    1	GND	Power ground
    2	VCC	Power 3.3V+
    3	SCL	Serial clock line
    4	SDA	Serial data cable
    5	RES	Display reset pin, low lever reset
    6	DC	Register select pin (instruction/data register selection pin)
    DC = ' 0' : Displaydata. (DC = ' 0' : Select command register) 
    DC = ' 1 ' : Displaydata. (DC =, 1' : Select data register)
    7	BLK	LCD backlight control, low level off backlight
    8	MISO	Serial clock line
    9	CS1	Display SPI chip selection
    10	CS2	Touch screen SPI chip selection
    11	PEN	Touch trigger output
    12	NC	Hanging
    

    To get started I'd just use software SPI so you can use whatever pins you want. Connect GND and VCC up to GND and 3.3v, then connect each pin to the easiest available IO pin.

    In terms of the software, probably start out with the ST7735 and copy the code from https://www.espruino.com/ST7735

    It should be pretty straightforward to map the pins given the data above, but any questions just ask :)
