[HELP]How to use the SPI interface of the TFT screen in arduino UNO?

TFT screen interface as shown in Fig.


I don't mean to be disrespectful and rude, as I was told that is bad :frowning: .

However, you cannot ask a question and give such scarce info. We need to know what LCD is it, and what driver it is using.

A good place to start is the UTFT library by Henning Karlsen, link provided below.

Once you have installed it, I recommend you open an example fit for the resolution of your LCD. You will need to change the line before void setup() to your particular LCD driver and connections.

However, I am not quite sure that this will work, since the library only has functions that support one wire serial.

You can also use the TFT library supplied with Arduino., however that only has one wire serial.
